Journal
Our journal is published in Japanese
We write about self-custody, wallet security and the practical side of running a hardware wallet. Those articles are currently available in Japanese only, so we have kept them out of the English site rather than show you machine-translated text.
If there is something you would like to know, ask us directly — we answer in English.
About this site
クリプトパーツ Akihabara
We sell hardware wallets for holding crypto and stablecoins yourself rather than with a custodian. What we write comes out of what we verify in the course of stocking and supporting these devices.
