Safe makers in Japan
Standard in force: JIS and maker-specific. Certifying bodies: —.
Where the grades come from
Every grade below is read from a certifying body's own public register: the ECB·S product locator,
which lists each certified model with its grade, and the VdS register, which also publishes the
certificate number. The figure is the company's highest grade for a free-standing safe —
most of a range sits lower, so the plate inside the door of the safe in front of you is what counts.
“Unverified” means we have not found the company in a register we can read — a statement about our
search, not about the product. Registers checked 14 Oct 2026.
| Maker | Founded | Highest safe grade | On the register | Status |
|---|---|---|---|---|
| Kumahira www.kumahira-safe.com | 1898 | — | not found in the ECB·S or VdS registers; national register not searched yet | unverified |
Grades are EN 1143-1. CD — also tested against core drilling; EX — against explosives; T2 — with the extended tool set introduced in 2019, explained here. VdS writes grade 0 as “N”; it is shown here as 0. Sites were reachable on the date recorded in our register. “Not confirmed” under Founded means exactly that: the year is repeated all over the trade press, and we have not yet seen a source worth citing.
