Is it bad to quit a job in Japan after only 1–2 weeks?

Hi everyone,

I started a new office job in Japan about a week ago, but I’m already feeling extremely overwhelmed and mentally exhausted. The workload and working environments are much heavier than I expected, and I’m really struggling.

I honestly don’t even have time to go to the restroom or drink water most days or even breathe. Everyone around me is always busy, and I feel pressured to just endure it.

I’m not trying to be irresponsible, but I’m honestly worried about my mental health. I’m considering quitting, but I feel guilty and scared because I just joined.

For anyone who has experience working in Japan:
Is it okay to quit this early?
Will it seriously affect my future job search?

I would really appreciate honest advice.

Thank you.
