Japan’s watches.
Understood from the inside.
Model-code references, JDM-only releases and the Japanese-language sources most English coverage never reads — written for people deciding what to buy, and where. We sell nothing ourselves: when a page points you to a shop, it is someone else’s, and the price carries the date we checked it.

Specs come from official documentation and Japanese-language sources, listed at the foot of the page so you can check us. If we can't source it, we don't state it.
We never tell you a watch will appreciate, and we never authenticate one. Both are jobs for someone else — we say who.
TOKI carries no inventory and ships nothing. We link out to several retailers and earn no commission on any of them — we hold no affiliate accounts.
We don't publish a price without the date we checked it. If we can't date it, we don't print a number — and we never claim a shop has stock right now.

What we do, and what we don’t
Official specs, manuals and Japanese-language releases — not forum hearsay repeated as fact.
Every reference, product and guide says which it is, at the top. Today all 17 read spec-based: we run no worn-review programme, and we do not invent wrist time.
No price goes up without the date we checked it, and we don't build a page around a single shop's link.
No investment calls, no authenticity verdicts, no vendor influence over what we conclude.
The full standard — sourcing, affiliate disclosure, and the lines we never cross — is on how we review.
