Small firm. Deep water.
Pier Head Japan is small on purpose: one accountable operator, a consultant's discipline, an AI operation behind it. Here's exactly who you're dealing with, and how work from overseas gets handled.
& THE HOUSE
Tsubasa Arai荒井 飛翔, bilingual consultant
One operator, a fleet's worth of output. Tsubasa pairs a management-consulting background with an AI operation that compresses the busywork. The result: a foreign company gets someone who can size a market, reach a Japanese executive, write the deck, and localize the site, at the speed of a team.
Fluent in written English and Japanese; outreach and calls run in native Japanese. Overseas work isn't new territory. A bilingual freelance practice, begun at university, served clients across the US and Europe in translation and business development — including one engagement retained for 24 consecutive weeks.
- One accountable operator. The principal owns every engagement end to end; you're never handed off to an anonymous team.
- AI as leverage, not the product. Automation and parallel research compress the hours; judgment and reporting stay human.
- External specialists only when named. If one is brought in, you're told, and the principal reviews every deliverable before it reaches you.
- Source-backed review. Nothing goes out as fact without the evidence attached.
We aim to be the pilot a foreign business can trust for the crossing, so no company has to enter Japan alone.
Built on a simple conviction: deep experience in a narrow niche, a strong point of view, and playbooks built from zero — put to work for companies that would otherwise face Japan without them.
Working with overseas clients
The questions a foreign company asks before sending work to Japan, answered up front.
NDA available
We'll sign yours, or provide one, before anything sensitive is shared.
English communication
All correspondence and reporting in clear written English by default.
Japan-time response
Replies within one Japan business day, with time-zone handoffs flagged clearly.
Invoice & currency
Invoiced in your preferred currency where possible; terms agreed before work starts.
Confidential handling
Research data and client materials are kept confidential, full stop.
Source-backed reporting
Findings carry their sources, so you can verify them instead of taking them on faith.
Email-first outreach
Outreach leads with email and web form, in Japanese — unsolicited phone calls are not our default channel. Respectful, and it works.
Text-first working
Async and written by default; calls only when they actually move things forward.
Deal with one name.
No account layers, no hand-offs. Send a brief and you'll be talking to the person who does the work.
