We build focused tools for travelers, collectors, and enthusiasts who care about the details. This is where every Kodama app, update, and announcement lives.
Launching SoonNavigate Tokyo's stations like a local.
Ground-truth navigation for Tokyo's busiest train stations, built for English-speaking travelers. Every route is verified on foot — real step counts, exact elevator and escalator locations, and the right gates and exits — so you spend less time lost underground.
In DevelopmentYour graded collection, tracked and valued.
A portfolio tracker for PSA and CGC graded cards and comics. Log your slabs by cert number, follow real eBay price history, and see your collection's total value at a glance.
Coming SoonThe archive for Japanese Domestic Market classics.
A true reference database for JDM legends — specs, production history, and rarity for the cars US enthusiasts actually care about. Built as an archive, not an auction feed.
Our tools are made for travelers, collectors, and hobbyists who care about the details others overlook.
Focused features, fast load, no bloat. Software that respects your time and attention.
Every release is logged on the announcements page. No surprises, no breaking changes.
