I will be visiting Tokyo as often as allowed by a 90 day tourist visa. I plan to withdraw/convert cash from an American/International bank with offices in Tokyo and really good access to ATMs. No foreign tx feed.
But after reading your articles about banking and brokerage in Japan, I realized I should ask if this ATM system will work. I realize ATMs are not 24 hours in Japan and you need to plan for your cash needs well in advance. I do not plan to use a credit card unless absolutely necessary such as plane tickets.
I will be traveling around nearby countries also with a 90-day visa, such as Taiwan and South Korea. And I want to keep up this rotation indefinitely. Sometimes going to other Asian countries. Sometimes skipping the second allowable 90-day visit to Tokyo. I read that eventually customs will accuse a person of trying to live in Japan without a residence visa. That’s exactly what I’m trying to do! Tokyo is the place I love most. I’m retiring soon. Any medical and financial needs that can be met in Tokyo, will be. My unofficial home base. I’ve read your post office article and it looks possible to set up a place for having mail forwarded from the US.
