Tuition is very expensive. Tuition in Japan is more expensive. In addition to tuition and fees, there are many miscellaneous fees, which add up to a lot. Although some people say it will be much cheaper than Europe, America and Australia. That's true, but for most working families, there is still great pressure to fully bear the various expenses of living and studying abroad, so many international students who go to Japan will still choose to work to earn part of their living expenses to reduce the burden on their families.
2 the cost of living is high. The cost of living in Japan is very high, and the price is much higher than that in China. Suppose that the average college student in China lives on 2000 yuan a month, but 2000 yuan is impossible to live in Japan, and it is not enough to eat. Many universities in Japan don't provide dormitories, so they need to rent their own houses outside. The cost of renting a house is also very high, comparable to the level of first-tier cities in China, plus the cost of water, electricity, coal and communication. If you don't work, the cost of asking your parents for living expenses is higher.
3 the work salary is high. The hourly wage for working in Japan is very high, because only a high salary can meet the high price. In Japan, there are also many policies to support the work of international students. It is easy to find a job. Just working a few hours a day is enough to pay for their own living expenses. In fact, it will not be very tired, and reasonable arrangements will not affect your studies. Part-time job can also exercise your Japanese level, and you can better master Japanese through Japanese communication.
In short, you can't neglect your studies while working, but you can still concentrate on your studies. If you feel that you can't work and study at the same time, give up your job or find something easier.
