Our Japanese practice

What we have been doing for twenty years

The English desk is not a new business. It is the same practice, pointed outward. Our Japanese clients hire us for these six areas, and the skills transfer directly.

Research

Market and business research

Reading public records, statistics, trade press and competitor material, then turning it into something a decision rests on.

Expansion

Overseas expansion support

Helping Japanese companies assess foreign markets — which is the same problem you have, viewed from the other side.

Operations

Remote assistant teams

We recruit, train and run remote administrative staff. That team is what staffs the Japan Desk.

Marketing

Digital marketing support

Acquisition, content and measurement for Japanese companies — useful when your product needs a Japanese-language presence.

Internal

Operations, DX and AI adoption

Working out how a company actually gets things done, and removing the steps that no longer earn their place.

Public support

Subsidy and grant advisory

Navigating Japanese public support schemes, which requires reading government documentation closely and accurately.

Scope

What we do, and what we will not do.

Several activities in Japan are reserved by law for licensed professions. We stay firmly on our side of that line, and we would rather tell you now than after you have paid.

We do

  • Research, verify and translate public and commercial information
  • Identify, screen, approach and correspond with Japanese companies
  • Attend places, meetings and events on your behalf
  • Interpret and translate in both directions
  • Map which permits, agencies and timelines apply to your situation
  • Handle scheduling, documents, forms and follow-up as your assistant
  • Introduce you to licensed lawyers, judicial scriveners, administrative scriveners and tax accountants

Introductions are made at no charge, to you or to them. We are paid only for the research, translation, interpretation and coordination work we actually perform.

We do not

  • Register or incorporate a company for you, or prepare its registration filings
  • Prepare or file visa, residence or licence applications with any government office
  • Give legal advice, or review or draft your contracts
  • Act as a real-estate broker or sign a lease on your behalf
  • Represent you in any dispute or negotiation as your legal agent
  • Take a commission or success fee on deals you close
  • Investigate private individuals

Under Japanese law these activities are reserved for licensed professionals, and the restriction applies regardless of what a fee is called. Anyone who offers to do them for you as “consulting support” is taking a risk on your behalf.

Why this desk

A Japanese company, priced like a freelancer.

Onmitsu Inc. has operated in Tokyo since 2006, doing research, market analysis and business support for Japanese companies. This desk is new. The company behind it is not.
