**Cold outreach is allowed in Japan, but cold email is generally subject to prior consent, with important exceptions for business contacts.** There is no blanket exemption simply because your message is business-to-business (B2B). Japan’s main email law is the **Act on Regulation of Transmission of Specified Electronic Mail (特定電子メール法)**. [e-Gov 法令検索](https://laws.e-gov.go.jp/law/414AC0100000026?occasion_date=20190131\&utm_source=chatgpt.com)

The practical distinction is **how you obtained the contact details and which channel you use**.

| Outreach situation | Position in Japan | Practical implication |
|---|---|---|
| **Email to a company address published on its website** | An exception generally permits advertising emails to addresses published by organizations or individuals conducting business, **unless a refusal notice accompanies the address**. | A published `info@company.jp` can be usable. Check for wording such as 「営業メールお断り」 before sending. |
| **Email after receiving a business card** | Providing an address directly can fall within an exception to prior consent. The privacy regulator also recognizes that company advertising may be an apparent purpose of business-card exchange. | Follow-up after a genuine exchange is generally possible, but stop if the recipient refuses. |
| **Email to an existing business contact** | A transaction relationship is another statutory exception. | An existing relationship can support outreach, but does not override a subsequent refusal. |
| **Guessed, enriched or purchased email address** | Finding an address does **not itself establish consent or an exception**. | Do not assume a verified address from a database is legally sendable. Establish its source and your sending basis. |
| **Advertising SMS** | SMS is also covered by the anti-spam framework. | It is not a workaround for email consent rules. |

Sources: the statutory exceptions, the Japan Data Communications Association’s explanation, the Personal Information Protection Commission’s business-card guidance, and its SMS reporting guidance. [e-Gov 法令検索](https://laws.e-gov.go.jp/law/414AC0100000026?occasion_date=20190131\&utm_source=chatgpt.com)

**Even when an exception permits the email, other requirements still apply.** Commercial emails must identify the sender, provide a clear refusal mechanism, include the sender’s address and a complaints/contact channel, and use truthful sender information. Once someone refuses advertising emails, further advertising sends are generally prohibited. Consent-based sending also requires retaining evidence of consent. An unsubscribe option alone does not make an otherwise unauthorized first email lawful. [迷惑メール相談センター](https://www.dekyo.or.jp/soudan/contents/taisaku/1-2.html?utm_source=chatgpt.com)

Other channels have different rules:

| Channel | What matters |
|---|---|
| **Cold telephone calls** | Genuine business-purpose transactions are generally outside the consumer telephone-sales provisions of the Act on Specified Commercial Transactions. Consumer calls face requirements including identifying the caller and sales purpose, and prohibitions on continuing or repeating solicitation after refusal. Merely calling someone a “business customer” does not automatically establish the exemption. |
| **LinkedIn messages** | Treat platform rules as an additional constraint. LinkedIn prohibits spam and can restrict accounts for policy violations. A connection acceptance should not be treated as permission to add someone to an external email campaign. |
| **Website contact forms** | Follow the recipient’s stated purpose and restrictions. Some companies provide a separate supplier-proposal form. The existence of a form does not establish that sales submissions are welcome. | :chatgpt-content-reference{index="3"}


**Personal-data rules are a separate layer.** A named employee’s details can remain protected personal information even when publicly available. If you collect them into a prospect database, you must address the applicable requirements, including specifying and notifying or publishing the purpose of use. Public availability is not a general exemption from Japan’s Act on the Protection of Personal Information. [ppc.go.jp](https://www.ppc.go.jp/personalinfo/legal/guidelines_tsusoku/?utm_source=chatgpt.com)

**How domestic companies deal with it**

The evidence supports several approaches, but does not establish what percentage of Japanese companies use each:

| Documented approach | Concrete example | Advantage and limitation |
|---|---|---|
| **Create a contact through exhibitions, then follow up** | Writeup’s August 2026 exhibition-follow-up service combines business-card capture, same-day email and next-day telephone follow-up. It explicitly limits emails to people who provided contact details and includes unsubscribe instructions. | Provides a clearer contact basis and conversation context; requires event participation and follow-up resources. |
| **Use dedicated channels for incoming sales proposals** | SALES ROBOTICS instructs sellers to use its separate proposal form. | Gives suppliers an accepted route; the seller must respect the recipient’s routing rules. |
| **Reject unsolicited email explicitly** | The Japan Data Communications Association recommends displaying a refusal notice alongside a public address. | Removes the public-address exception for unsolicited advertising to that address. | :chatgpt-content-reference{index="5"}


For your B2B outreach, my practical recommendation is to record **where each address came from, the consent or exception supporting contact, and any refusal** in your customer relationship management (CRM) system. Published business addresses without refusal notices and genuine business-card contacts offer clearer grounds than guessed employee addresses. Keep messages relevant, identify your company fully, provide an easy opt-out, and suppress refusals across future campaigns. This recommendation follows the rules above; it is not evidence that every domestic company operates this way.

**Japan permits cold business-to-business (B2B) outreach, but email has specific restrictions.** The default is prior consent, with exceptions including publicly disclosed business email addresses, business cards, and qualifying existing business relationships. Being a business recipient does **not** itself exempt an email from the law. [caa.go.jp](https://www.caa.go.jp/policies/policy/consumer_transaction/specifed_email/pdf/090901email_1.pdf?utm_source=chatgpt.com)

The key distinction is **how you obtained the contact details and which channel you use.**

For email, the main law is the **Act on Regulation of Transmission of Specified Electronic Mail**, commonly called 特定電子メール法.

| Situation | Can you send an unsolicited sales email? |
|---|---|
| A company publishes its contact email on its website, without an accompanying refusal of advertising emails | **Generally yes**, under the public-address exception. |
| The published address has “営業メールお断り” or equivalent wording alongside it | **You cannot rely on the public-address exception.** |
| Someone directly gives you their business card containing their email | **Generally yes**, under the written-address-notification exception, subject to subsequent refusals. |
| You have a qualifying existing business relationship | **Generally yes.** |
| You guess an employee’s address or obtain an unpublished address from a prospecting database | **Not automatically permitted.** You need consent or another applicable exception; possession of the address is insufficient. |

These exceptions come from Article 3 and the government’s guidance. A publicly listed company address does not authorize sending to every employee at that domain. [caa.go.jp](https://www.caa.go.jp/policies/policy/consumer_transaction/specifed_email/pdf/090901email_1.pdf?utm_source=chatgpt.com)

**Even when an exception permits the email, you still need:**

- The responsible sender’s name or company name.
- A clearly explained way to refuse future emails, using an email address or unsubscribe URL.
- Sender address and a contact channel for complaints or inquiries.
- Accurate sender information, and cessation of promotional emails after a refusal. [迷惑メール相談センター](https://www.dekyo.or.jp/soudan/contents/taisaku/1-2.html?utm_source=chatgpt.com)

A personalized, manually sent pitch does not gain an exemption simply because it is one-to-one. Also, **“May I send you information about our service?” is not a universal workaround**: government guidance treats emails seeking advertising-email consent as covered messages themselves. [caa.go.jp](https://www.caa.go.jp/policies/policy/consumer_transaction/specifed_email/pdf/090901email_1.pdf?utm_source=chatgpt.com)

Other channels work differently:

| Channel | Regulatory position |
|---|---|
| **Cold telephone calls** | Genuine business-purpose transactions are generally excluded from the consumer telephone-sales provisions of the Specified Commercial Transactions Act. Consumer calls have identification requirements and a prohibition on continuing or repeating solicitation after refusal. [no-trouble.caa.go.jp](https://www.no-trouble.caa.go.jp/what/telemarketing/?utm_source=chatgpt.com) |
| **Website contact forms** | Japanese providers actively offer *フォーム営業*. However, a publicly accessible form is not blanket permission: its purpose, terms, and “no sales” wording matter. Providers themselves instruct users to exclude prohibited targets. [株式会社エンカレッジ](https://www.encourage-sol.jp/column/form_sales/20260724_column?utm_source=chatgpt.com) |
| **LinkedIn and other ordinary in-app messages** | These are generally outside the email/SMS regime, but platform restrictions apply. LinkedIn prohibits unauthorized automated messaging and scraping. [salt.iajapan.org](https://salt.iajapan.org/wpmu/anti_spam/admin/2008_qanda/qa_basic/?utm_source=chatgpt.com) |
| **Short Message Service (SMS)** | Advertising SMS is covered by the email law. It is not an alternative route around consent requirements. [caa.go.jp](https://www.caa.go.jp/policies/policy/consumer_transaction/specifed_email/pdf/specifed_email_180709_0001.pdf?utm_source=chatgpt.com) |

There is also a separate privacy layer. Under the **Act on the Protection of Personal Information (APPI)**, identifiable employee information remains personal information even when publicly available. Public availability does not remove obligations concerning use purposes and handling. The Personal Information Protection Commission explicitly recognizes ordinary business-card follow-up for the collecting company’s advertising, while requiring compliance with the email law too. [ppc.go.jp](https://www.ppc.go.jp/personalinfo/legal/guidelines_tsusoku/?utm_source=chatgpt.com)

**How Japanese companies handle it in practice**

These are documented examples, rather than evidence that every domestic company follows the same approach:

| Approach | Concrete Japanese example |
|---|---|
| **Email publicly listed business addresses, with opt-out controls** | **B.O.N’s Reachill**, launched September 2026, says it restricts recipients to legally eligible addresses, includes sender and opt-out information, and stops after refusal. [株式会社B.O.Nのプレスリリース](https://prtimes.jp/main/html/rd/p/000000002.000188229.html?utm_source=chatgpt.com) |
| **Build email lists from business cards and existing contacts** | **Rakus’s 配配メール** support documentation says many customers use business cards, customer lists, and internal databases, while explaining the consent exceptions. [配配メールサポートサイト](https://support.haihaimail.jp/utilization-lecture/destination/?utm_source=chatgpt.com) |
| **Use contact-form outreach with exclusions** | **Encourage** instructs users to remove companies prohibiting sales approaches, previous stop requests, and duplicate targets. [株式会社エンカレッジ](https://www.encourage-sol.jp/column/form_sales/20260724_column?utm_source=chatgpt.com) |
| **Explicitly refuse unsolicited email as a recipient** | **Dai-Ichi Tsushinsha**, a Kodansha Group company, publishes its contact email alongside a request not to send sales or other specified advertising emails. [講談社グループ](https://www.ittsu.ne.jp/contact/?utm_source=chatgpt.com) |

**For your outreach, my practical recommendation:** record the source and permission basis for each email address, check refusal wording before sending, include a clear opt-out, and maintain a shared suppression list. Public company inboxes provide a clearer basis for cold email than guessed employee addresses. They may, however, require another step to reach the decision-maker. That last trade-off is a practical assessment, not a statutory rule.

**Cold outreach is possible in Japan, including business-to-business (B2B) sales. But there is no blanket B2B exemption from the email rules.** The key is whether you have consent or qualify for a specific exception. [e-Gov 法令検索](https://laws.e-gov.go.jp/law/414AC0100000026?occasion_date=20180418\&utm_source=chatgpt.com)

Even when an exception applies, promotional emails need the responsible sender’s identity, an accessible opt-out email address or URL, clear opt-out wording, and required address/contact information. **An unsubscribe link does not, by itself, authorize the first email.** Consent-based sending also requires retaining evidence of consent.

Other channels differ:

- **B2B cold calls:** Genuine business-purpose contracts are generally excluded from the Specified Commercial Transactions Act’s consumer telemarketing provisions. Calling someone at work does not automatically make a consumer sale B2B.
- **Consumer telemarketing:** Disclose the company, caller, product/service type and sales purpose before solicitation. Continuing or repeating solicitation after refusal is prohibited. [no-trouble.caa.go.jp](https://www.no-trouble.caa.go.jp/what/telemarketing/?utm_source=chatgpt.com)
- **LinkedIn messages:** In-platform messaging is generally distinct from conventional email, but platform restrictions apply. LinkedIn expressly treats excessive, irrelevant or repetitive messages as spam. [内閣府](https://www.cao.go.jp/consumer/iinkaikouhyou/2023/0810_iken.html?utm_source=chatgpt.com)

There is also a separate privacy layer: **named contacts and identifiable work email addresses can be personal information under the Act on the Protection of Personal Information (APPI), even when publicly available.** Public availability does not remove privacy obligations.

| **Obtain permission before mailing existing contacts** | **Chiba Television** consulted counsel about reusing business-card data.

| **Nurture business-card and customer lists** | **JoB-up** describes weekly emails followed by individualized outreach based on website activity. The case documents its workflow; it does not establish every recipient’s legal basis. [bow-now.jp](https://bow-now.jp/media/cases/job-up/?utm_source=chatgpt.com) |
| **Combine phone prospecting and contact-form sales** | **GC Story** used Sales Marker’s form submissions and outsourced appointment-setting calls for customer development. [株式会社Sales Marker(セールスマーカー)](https://corp.sales-marker.jp/gc-story-20240523/?utm_source=chatgpt.com) |
| **Build refusal controls into form outreach** | **Smart Kaitaku** says it excludes forms marked “営業お断り,” includes suppression links, and avoids resending to the same company for one month. That interval is its operating policy, rather than a statutory permission to resend. [smartkaitaku.com](https://smartkaitaku.com/form/faq.html?utm_source=chatgpt.com) |

**Contact-form sales exists commercially, but I found no official blanket ruling that every form submission is lawful.** A vendor offering it is not sufficient legal assurance.

For your HubSpot setup, there is an additional constraint: its **February 2026 anti-spam policy requires express, verifiable consent through a documented opt-in process**, with limited exceptions. An email may qualify under Japan’s public-address exception yet still breach HubSpot’s sending policy. [legal.hubspot.com](https://legal.hubspot.com/anti-spam-policy?utm_source=chatgpt.com)

# Cold Outreach Regulations in Japan

Japan’s cold outreach regulations are primarily governed by three legal frameworks: the Act on Regulation of Transmission of Specified Electronic Mail (Anti-Spam Law), the Act on Specified Commercial Transactions (ASCT), and the Act on the Protection of Personal Information (APPI). Under the Anti-Spam Law, Japan mandates a strict opt-in consent model for commercial emails, meaning prior permission is generally required before sending a cold pitch (MailTester, 2026-08-29). However, the law includes a narrow B2B exception (Article 3) that permits unsolicited emails to corporate addresses that a business has publicly published (Imisofts, n.d.). Sending emails to fictitious or randomly generated addresses to evade spam filters is strictly prohibited (Japanese Law Translation, n.d.). Furthermore, under the APPI, explicit opt-in consent is required to use personal data for marketing, and failing to prove consent can lead to significant fines (MailTester, 2026-09-27).

For cold calling (telemarketing), regulations fall under the ASCT, which requires sales representatives to immediately disclose their company name, their own name, and the exact purpose of the call upon connecting (DataGuidance, 2025-10-08). The law also enforces a "cooling-off" period for consumers who sign contracts during unsolicited calls, allowing them to cancel without penalty (Consumer Affairs Agency, n.d.). If a prospect explicitly requests not to be contacted, the company must cease outreach and honor their refusal.

Because of the strict regulatory environment and a deeply trust-based business culture, mass cold outreach strategies generally perform poorly in Japan compared to Western markets (YKBridge, 2026-09-21). Domestic companies deal with these regulations and cultural norms in the following ways:

1. **Relying on Warm Introductions (Nemawashi):** Instead of mass blasting lists, domestic companies rely heavily on *Nemawashi*—the process of laying the groundwork and building trust behind the scenes before making a direct pitch (LinkedIn, n.d.). Trust precedes the deal, so warm referrals from mutual connections are the most effective outbound strategy.
2. **Social Selling and Relationship Building:** Sales teams often engage with prospects on social media first—such as commenting on or resharing a prospect's posts—to make the eventual outreach feel less like a "cold knock" (LinkedIn, n.d.).
3. **Strict List Hygiene and B2B Carve-outs:** When companies do send cold B2B emails, they meticulously curate their lists to ensure they only target corporate domains and publicly listed contact forms to remain compliant with the Specified Email Act's B2B exceptions (Span Global Services, 2026-09-15).
4. **Inbound Consent via Events and Content:** To legally capture leads, Japanese companies heavily invest in gated content, webinars, and industry trade shows where the physical exchange of business cards (*meishi*) serves as an implicit or explicit opt-in for future communications. Cold outreach to Japanese enterprises is often viewed as close to useless without this foundational relationship building (Techro, n.d.).

## K3 · High (Moonshot)

Here's a breakdown of Japan's cold outreach rules and how Japanese companies actually work around them.

## The regulatory landscape

**Cold email — the strictest channel**

Japan is one of the most restrictive jurisdictions in the world for cold email. The Act on Regulation of Transmission of Specified Electronic Mail （特定電子メール法， amended 2008) requires **prior opt-in consent** before sending commercial email — you cannot legally blast unsolicited pitches the way you can in the US under CAN-SPAM's opt-out model. The law also applies to foreign senders targeting recipients located in Japan.

Key requirements:
- **Consent records** must be kept — under the ASCT, proof of consent is retained for three years after the last email.
- Every email must include sender identification (company name, address, contact info) and a working opt-out mechanism.
- Auto-generated or "dictionary attack" addresses are explicitly banned.
- Penalties: up to ¥30 million for corporations, plus public naming by regulators.

**The critical B2B carve-out**: consent isn't required for email sent to an address the recipient has *voluntarily disclosed for business purposes* — e.g., a contact address published on a corporate website, or a business card exchanged at an event. Personal Gmail/Yahoo addresses don't qualify, even if used for work.

**Cold calling — less regulated than email**

Telephone solicitation rules under the Act on Specified Commercial Transactions （特定商取引法） mainly target **consumer** sales: callers must identify themselves and their purpose upfront, and once a consumer says no, re-solicitation is prohibited. Pure B2B cold calling is largely outside these consumer-protection provisions, though it runs into APPI issues around how you obtained the contact data, and it carries a strong cultural stigma (more on that below).

**APPI — the data layer**

The Act on the Protection of Personal Information governs how you acquire and use contact data. Buying scraped lists or improperly sharing personal data can trigger PPC enforcement — corrective orders, and for serious violations, entity fines up to ¥100 million. An amendment passed in July 2026 will give the regulator power to impose administrative fines for improper data acquisition or unlawful third-party provision, expected to take effect by 2028.

## How domestic companies actually deal with it

Japanese sales culture and regulation reinforce each other — the result looks very different from US-style outbound:

1. **Business cards and events as the consent mechanism.** The meishi (business card) exchange isn't just etiquette — it's the classic legal basis for the "voluntarily disclosed for business purposes" exemption. Trade shows, seminars （セミナー), and industry association events are structured lead-generation machines precisely because exchanging cards there legitimizes follow-up.

2. **Database platforms with built-in provenance.** Services like Sansan digitize business cards so the consent trail is automatic, and B2B data providers (Baseconnect, SalesNow, etc.) sell lists of *publicly disclosed corporate addresses* — which map to the B2B carve-out — rather than personal addresses. Companies log the source URL and date for each address to defend the exemption.

3. **Referral-first selling （紹介営業）.** Warm introductions through banks, trading companies, existing customers, and industry associations are the dominant enterprise sales channel. Cold outreach to a stranger without any connection is culturally suspect regardless of legality — it signals you lack a network.

4. **Inbound marketing as the substitute.** Content marketing, whitepaper downloads, and webinar registrations generate *opted-in* leads that can be legally emailed and called. Many Japanese B2B companies (especially SaaS) have shifted budget from outbound to inbound/SEO for exactly this reason.

5. **"Forms sales" （フォーム営業） as a gray zone.** A distinctly Japanese workaround: instead of emailing individuals, reps submit pitches through the inquiry form on a company's official website. It's legal because that address/form is published for business inquiries — though mass-automated form spam has drawn criticism and some companies now block it.

6. **Cold calls survive, but softened.** B2B "teleapo" (telephone appointment) agencies are a real industry, but scripts are heavily formalized: identify company and caller immediately, ask for the relevant department rather than a named person (avoiding personal-data issues), and accept refusal instantly. Aggressive US-style cadences are rare.

**Bottom line**: Japan's regime is opt-in for email with narrow B2B exemptions, consumer-focused but culturally constraining for calls, and increasingly strict on data sourcing. Domestic companies respond not by fighting the rules but by engineering consent capture into everything — cards, forms, events, referrals — so that by the time they reach out, it rarely counts as truly "cold."

If you're planning outreach into Japan specifically (e.g., as a foreign company), I can go deeper on compliant sequence design or the deliverability side (Docomo/KDDI filtering, Japanese mailbox providers).
