In some departments, taking leave or compensatory time off is met with all kinds of difficulties and refusals; in others, even the most arbitrary reasons are approved.
For compensatory time off for holiday support activities, if you are maliciously obstructed until the deadline passes, HR will automatically swallow it up.
They nitpick over all kinds of attendance and tardiness issues; being one minute late is included in performance evaluations, while all kinds of overtime are not.
Labor and health insurance are provided, but during the first week of the probationary period, they will not enroll you in either.
This year's year-end bonus was one month's salary, but only half was paid. HR announced, "The other half will be paid in March if the company doesn't go under."
The reason is:
Most employees have been here for less than a year, so they cannot receive a full month's bonus anyway. Calculated proportionally, some people received only a few thousand dollars. So they might as well pay the salary first.
It's just like a pyramid-selling company: they talk about dreams all day, claim you can live on dreams, and say salary isn't important. You might as well not get paid at all.
The promotion system is indeed quite good, but it is limited to those who know how to flatter, take credit for achievements and hard work, speak loudly enough, and be extremely obedient. If you quietly complete your own work, you will not be promoted, and may not even have a chance to receive a raise.
(Just like certain male managers/colleagues.)
For some positions, language requirements are indeed flexible, but the boss is Japanese. Although he speaks a little Chinese, he is actually still very poor at it, and often fails to express himself clearly, so you have to guess what he is trying to say or needs. If you make a mistake or say something wrong, he will accuse you of having poor communication skills.
Overall, knowing Japanese is still preferable, and many Japanese colleagues internally cannot speak Chinese.
If the position you are applying for requires contact with Japanese colleagues, think twice if you do not know Japanese. (Colleagues who can communicate in Japanese will not always be available to translate for you; most of them are being exploited terribly.) In some departments, if your Japanese is not good, you may even be mocked in Japanese.
On the surface, it is a Japanese company, but inside it is full of deputy blackness—an extremely exploitative, two-faced fake Japanese company.
