Living in Japan. Any opinions on amplifiers?

Living here I figured I would be in audio heaven but it seems like Japan falls in love with certain brands and ignores others. Since I need to buy something here 100V I’m wondering if any of you have an idea of underrated/overlooked value products currently in production. I know this sounds like a lame question and that I should do research but my Japanese still sucks and I thought there might be a few of you who are familiar with what is available here now. I have looked at vintage Luxman and there are a lot available but I thought a current production amp would be more practical and utilized modern technology Ie streaming etc.
