Yes. TSE kessan tanshin (quarterly disclosure), yuho (annual securities report), and SEC 20-F foreign-filer translations are routine work. We translate from Japanese into English, Mandarin, and Korean for the regional investor base, with terminology calibrated against the JICPA accounting glossary and the issuer's prior filings; project managers map files against the TSE disclosure window and the SEC 20-F deadline so language production never sits on the critical path.

Why Day Translations
Calibrated to Tokyo's disclosure-bound working day.
Since 2007 we’ve been the linguistic operations layer for Marunouchi finance houses and Tokyo Stock Exchange filers, Roppongi BigLaw cross-border M&A teams, Toyota, Nissan, and Honda supplier networks running IATF 16949 audits, and the Nintendo, Sony, and Capcom gaming HQs running global launch calendars from Akihabara to Shibuya. Keigo-fluent Japanese linguists trained for legal and medical formal register; FIGS+CJK localization teams for gaming and anime; ISO 17100 technical translators paired with automotive supplier glossaries.
That same Tokyo operations layer runs on ISO 17100 quality and ISO 27001 security, with HIPAA-aligned protocols and a SOC-2 readiness program for US-listed clients — calibrated to the city’s actual working day. A TSE quarterly disclosure on Monday morning, a Toyota Tier-1 supplier IATF 16949 audit pack Tuesday afternoon, and a Capcom global launch FIGS+CJK package that Friday all route through the same audit-ready vendor without you switching providers mid-week.

Why Tokyo
Built for Tokyo's deadline-bound disclosure workflows.
When timelines collapse and a single document can shift a TSE disclosure, a Toyota PPAP submission, or a Capcom global launch — these are the operational realities the city demands, and what we set up our Tokyo work around.
