Hey all,

I'm got my visa issued and I'm prepping for my first trip back to Japan since 2019. I feel up to date on everything that I need to do with the exception of one thing, this MYSOS app.

My understanding was originally it was for quarantining and to give the government a way to track you/be in contact with you during quarantine. But I'm wondering now with the lifting of many restrictions how the app works now. I haven't really seen any updated info about the app on the government's site.

For reference purposes, I'm a vaccinated and boosted US citizen travelling on a US passport. Per the latest that I read, I don't need to either test or quarantine. So what am I using the app for and what should I expect to happen?

Thanks for any experience/advice you can give.
