How do I invest my extra income as a student?

I’m a 20-year-old first-year college student and a permanent resident in Japan. My goal is to pay off half of my tuition, which is about 250万円, by the time I graduate.

Right now, I earn around 8万~11万円 per month from work, and I also borrow 10万円 per month through student loans. Combined, that gives me about 20万円 per month in income. My only real expenses are school-related, mainly transportation and food.

My tuition costs 50万円 every 6 months, so about 100万円 per year. After paying tuition, I still have around 20万円 per year left over to invest.

I’ve already opened a 楽天銀行 (Rakuten Bank) and 楽天証券 (Rakuten Securities) account for my NISA. My plan is to invest between 5万~8万円 per month, plus the extra 20万円 per year from my student loans. I don’t want my money to just sit in my bank account without growing.

Is this too risky of a move? Or is there a better way I should be investing my money?
