Is 188,000/m after taxes enough in Osaka, Japan?

Hi all, I recently received an offer from a Japanese company for a Software Engineer role with an in-hand salary of around 188,000 ¥ per month (after taxes). Additionally, they’ll provide 20,000 ¥ per month as a house rent allowance. I’m a new grad, graduating this year, and I wanted to know how much new grads typically earn as Software Engineers in Osaka, Japan, and what my expenses might look like (e.g., electricity, Wi-Fi, food, etc.). Will I be able to save anything with this salary?

Edit: The company also has a 26-month bond (planning to extend to 36-month...), and if I leave before completing this period, I’ll have to pay 420,000 ¥ (equivalent to two months salary).

Also, the company mentioned that they won’t cover flight charges but will provide a loan for it, which will be deducted from my monthly salary.

Edit: Original offer was fo 250k/m for N3 but they reduced it to 210k/m for N4 and with all deductions it comes down to 188k/m. They are some sort of IT dispatch company.

Additional things offered:
750,000 ¥ per year performance bonus
15,000 ¥ per month commuting allowance
