Can international students in Japan invest via NISA or Japanese/US stocks?

Hi everyone,

I’m an international student studying in Japan and currently working a part-time job. Instead of just saving my income, I’d like to start investing small amounts regularly and learn how to manage my money better.

I’ve heard about NISA, investing in US stocks from Japan, and also investing in companies listed on the Tokyo Stock Exchange through brokers like Rakuten or SBI. However, I’m a bit confused about what’s actually possible for international students and how the process works in practice.

I’d really appreciate advice on:

• Whether international students are eligible for NISA, and which type makes sense
• How investing in Japanese stocks (TSE) and US stocks from Japan works
• What kind of accounts and documents are usually required
• Any beginner-friendly advice on investing while studying (risk level, amounts, things to avoid)

I’m not looking to take big risks — mainly trying to learn and make better use of my part-time income instead of leaving it idle.

Thanks in advance to anyone willing to share their experience or advice.
