Want to succeed in Japan’s growing SaaS market? Start with mastering email etiquette.

Here’s what you need to know:

• Respect is key: Use formal titles, polite language, and indirect phrasing.
• Group-focused communication: Copy all stakeholders, provide detailed info, and allow time for decisions.
• Email structure matters: Begin with a seasonal greeting, clearly state your purpose, and close with formal expressions.
• Technical details: Use UTF-8 encoding, keep emails mobile-friendly, and comply with Japanese anti-spam laws.
• Marketing tips: Highlight team benefits, use local case studies, and craft clear subject lines.

Japanese Business Communication Basics

Effective Japanese business communication influences email outcomes and helps establish strong partnerships. Below, you’ll find key etiquette practices for professional email exchanges.

Respect and Politeness Standards

Japanese communication relies heavily on keigo (honorific language) and formality, which impacts every aspect of an email.

Here are some essential practices to show respect in your emails:

• Title Usage: Always include formal titles, such as "Department Manager Smith-sama", instead of simply "Mr. Smith."
• Company Before Name: Mention the company name before the recipient’s personal name to acknowledge their position.
• Polite Language: Stick to polite expressions and avoid casual wording, even in follow-ups.

Japanese communication often favors indirect phrasing. For example, instead of saying, "Please review this proposal by Friday", a more culturally appropriate version would be, "We kindly request a review of the proposal by week’s end."

Group Decision-Making Process

Japanese emails reflect a collective approach to decision-making, prioritizing group harmony and consensus.

When writing emails for Japanese stakeholders, consider these points:

1. Include All Stakeholders
   Copy all relevant parties to acknowledge the group-oriented decision process.
2. Provide Detailed Information
   Ensure proposals are thorough to facilitate internal discussions.
3. Be Patient with Timelines
   Japanese decision-making takes time, as it involves careful consensus building.

Japanese Email Writing Guidelines

Writing business emails in Japan requires attention to specific formatting and language norms. Here’s how to create professional emails that align with Japanese business etiquette.

Opening and Closing Lines

Japanese business emails follow a structured format, starting and ending with formal expressions. Key components include:

Maintain a formal tone throughout, especially when discussing technical details.

Professional Language Rules

In addition to formal greetings, your language should consistently reflect respect and precision.

• Using Titles Properly
  Always include the correct honorific when addressing someone. For example:
  "Tanaka-sama, Toyota Corporation Information Technology Division"
• Structuring the Message
  Begin with a brief context before making a request. For instance:
  "We understand your team is evaluating cloud solutions. We request a conference at your convenience."
• Choosing Formal Expressions
  Replace casual phrases with more formal alternatives:
  • Instead of: "Let’s set up a call"
  • Use: "We request a conference at your convenience"

Response Times and Follow-Ups

Timing is crucial in Japanese business communication. Acknowledge emails promptly, even if a detailed response requires time. For example:
"Thank you for your inquiry. We will provide a detailed response after internal review."

If no reply is received after a reasonable period, follow up respectfully:
"Please advise on the status of our previous correspondence."

Japanese companies often need extra time for internal discussions before responding. Adjusting your follow-up approach to respect this process will strengthen your professional relationship.

Email Technical Requirements for Japan

When emailing Japanese business contacts, following specific technical guidelines is essential for effective SaaS communication.

Japanese Text and Layout Standards

Use UTF-8 encoding for Japanese emails. However, legacy systems might require ISO-2022-JP instead.

Here’s how to format key elements in Japanese business emails:

Research from Nihonium indicates that using 1.5× line spacing improves mobile readability by 27%. This is especially important since 78% of Japanese professionals check emails on their smartphones.

To ensure clarity and readability:

• Keep paragraphs short (2–3 lines) and align text to the left for better kanji visibility.
• Use fixed-width tables (up to 600px) for multi-column layouts.
• Provide both HTML and plain text versions of your email and keep the total size under 50KB.

These guidelines set the foundation for text and layout. However, mobile email design requires further adjustments to meet the specific needs of Japanese professionals.

Mobile Email Design for Japan

Optimizing emails for mobile is crucial in Japan, where 78% of professionals rely on mobile devices for email communication.

• Image Optimization: Compress images to under 100KB each to account for varying network speeds. Avoid animated GIFs, as many Japanese mobile carriers block them.
• Touch-Friendly Design: Ensure interactive elements are at least 48×48 pixels for easy navigation on touchscreens.
• Carrier-Specific Requirements: A technical audit found that 38% of email layouts failed in Japanese email clients when fixed-width tables weren’t used.

To confirm your email setup is ready for Japanese audiences:

• Use tools like Litmus to test rendering in Japanese email clients.
• Check spam scores with local tools such as SpamAssassin-JP.
• Test load times on networks averaging 15 Mbps.
• Verify proper display across all major Japanese mobile carriers.

Additionally, Japanese anti-spam laws require strict compliance. Commercial emails must include sender verification through services like GMO Proofpoint and process unsubscribe requests within 24 hours. Failing to comply can result in fines of up to ¥1 million (approximately $6,700 USD) per violation.
