初めまして。Hey @momoka, welcome to Steemit! A few things:

1. Use 5 tags. Since you are new one of them should be #jp-newbie. We use this tag to vote on new Japanese users. Also the #introduceyourself tag.
2. Our Japanese community discord server here: https://discord.gg/FKQ2eV
3. Post in Japanese as well as English. Many Japanese users don't read English so it will help you make friends easier.

I'm @rt395, part of the @steemit-jp community. Hope this helps! Sorry I wrote in English!
よろしくお願いします！
