I'm building AltStack.jp to help people discover Japanese alternatives to popular international tech services (cloud hosting, VPS, email providers, etc.), with an eye on compliance with Japan's privacy laws (APPI).
It's inspired by european-alternatives.eu, but focused entirely on Japan.
There are still only four categories, no search, so it's still very much a work in progress!
I'd love feedback, suggestions, or feature ideas! Thanks.
