Docs needed for family visiting Japan?

Hello! I need advice from anyone who’s been in a situation like mine. I’m a student here, and my mom’s coming to visit me for a few days (our country doesn’t need a visa for short stays).

Is it enough to just put my address under “Address in Japan (Accommodation)” on the Visit Japan site, or does she also need stuff like a Letter of Invitation, a family register copy, Letter of Guarantee, etc.?
