Underrated Japanese Areas?

Hello!

I’m thinking of applying for the JET programme when it opens up – FYI I’m a 35 year old Singaporean with ~12 years of marketing work experience.

I did some research and apparently we’ll need to select 3 preferred areas to work at in Japan, am I right?

Does anyone have underrated areas to recommend and why? I don’t want to select the usual big cities like Osaka & Tokyo etc..

Thanks in advance 😊
