I remember so many people doubted that Mercari, a Japanese company, would do well in the US. Well, they just announced their results: monthly GMV reached $100m, up 183%!

Congrats to @suadd and the folks at Mercari for such an impressive achievement!

Re Japan’s foreign resident re-entry ban, some have replied suggesting that if you’re not a citizen, shoganai.

To be clear, we are not citizens, so I don’t expect complete equality. But being able to return home seems like a reasonable baseline that should be respected.
