What is life like on 300-350k monthly salary?

I‘m a student in Tokyo (21) and currently considering future career options. If things continue on their current trajectory, I will be looking at 300-350k monthly salary. What kind of life does that afford in Tokyo and other cities?

My current expenses are about 200k a month, so by my reasoning I should be fine. But I don’t know how this adds up long term and how financially stable that life really is. Reason I ask is, I‘m from a high income family and my parents are getting more and more pushy about my career choice, asking me to do sth better with more pay. I told them this is a normal salary in Japan and that my life won’t be so bad. Can someone please share their experience?
