Selling to Japanese companies? They will send their own security checksheets and vendor forms in Japanese, separate from SIG or CAIQ. Moshiru drafts the answers from the documents you already have, by email only.

How it works
Three steps, all by email
- Email us what you received (the questionnaire or form) and the documents you can share.
- We send a fixed quote by email. Work starts after payment.
- You get the drafts in Japanese, with English notes on anything we could not confirm from your documents.
What we don't do
Clear lines, so you can trust the drafts
- We don't log in to your systems or submit anything on your behalf.
- We only write what your documents support. Anything we can't confirm is marked for you to check.
- We don't give legal or tax advice, and we don't certify compliance.
Who we are
A small security practice in Tokyo
Moshiru is a security practice in Tokyo, run by Yuta Okazaki. Yuta previously led security incident response at a major Japanese automaker, and before that worked in B2B sales for a corporate data platform.
We use AI (Claude) to draft, and every deliverable is reviewed by Yuta before it goes out. Your documents are used only for your project.

Got our 3-question email?
We're asking SaaS companies how often Japanese-language questionnaires show up and whether they slow deals down. One-line answers by reply are perfect. Everyone who replies gets the anonymized summary.
