Neo broker apps

Hi everyone,

I’m a German resident but also living in Japan, and I’m trying to figure out the best way to invest. In Germany I could just use apps like Trade Republic or Scalable Capital, but in Japan it looks like most of the major brokers (SBI, Rakuten, Monex) only offer apps and websites in Japanese, which I can’t really navigate.

So my questions are:
• As an expat in Japan, what app do you use for investing?
• Are there any Japan-based apps with an English interface, or do most people just go with international brokers like Interactive Brokers or Saxo Bank?
• Any advice on handling the tax side as an expat – whether it’s easier to keep a brokerage account in your home country or to open one in Japan?

I’d really love to hear what others in the same situation are doing. Thanks a lot for any tips!
