Are these working hours normal or should I continue looking for Jobs?

Hi all,

I applied to a job using jobs in Japan and have had my first interview with a company to work in HR. They explained to me that most employees work 1-2 hours of overtime a day. Is this considered okay? or would this be considered a black company? Should I continue applying for other jobs?

I am sorry in advance, I just want to make sure before I continue talking with them. The salary would be in the 4 million range and with bonuses.

Any advice would be greatly appreciated.
