Using an Interpreter for Investor Calls with Japan

By the Hanabuddies team · · 3 min read

If you are raising money from Japanese investors, talking to a Japanese corporate venture team, or answering due diligence questions from a Japanese partner, a live English–Japanese interpreter on the call lets both sides speak precisely in their own language. Many Japanese investors read English well but prefer to ask detailed questions in Japanese, and an interpreter makes sure nuance around numbers, risks and terms isn’t lost. Book the interpreter early, send your deck and financial terms in advance, plan for the call to take longer, and agree how you will handle confidential material.

When an interpreter helps

  • Pitch and follow-up meetings with Japanese venture capital firms, corporate venture arms or angel investors.
  • Due diligence calls, where detailed questions about finances, contracts, technology and team need exact answers.
  • Partnership and strategic investment talks with Japanese companies, where several departments may join.
  • Board or shareholder updates when some participants are more comfortable in Japanese.

Even when the main contact speaks English, senior decision-makers may join later meetings and speak only Japanese. Having an interpreter ready shows respect and keeps the process moving.

Preparing the interpreter

  • Your deck and one-pager, ideally in both languages. See preparing a pitch deck for Japanese investors.
  • Key numbers and terms: revenue metrics, valuation, round size, instrument (for example, equity or convertible notes) and any acronyms you use.
  • A glossary of product names and technical words, and how you want them said in Japanese.
  • The agenda and attendees, with names, titles and companies, so the interpreter can use the right forms of address.
  • A confidentiality agreement, if you need one, before any material is shared.

Running the call

  • Allow extra time. Consecutive interpreting roughly doubles speaking time, so plan a 30-minute pitch as a 60-minute call.
  • Speak in short sections and pause, especially when giving numbers. Say figures clearly: Japanese counts in units of ten thousand (万), so large numbers need care.
  • Share your screen and point to the slide you are discussing.
  • Look at the investor, not the interpreter, and speak to them directly.
  • Expect careful questions. Japanese investors often ask about risk, long-term plans and how you will support the relationship. Short answers can be followed by a request for a written follow-up.

After the call

Send a short written summary of what was agreed and what you will provide next. A Japanese version of the summary, or of key documents, helps the investor share it inside their organisation, where approval often involves several people.
