You can wait until the economy improves, or you can study Japanese well during this time. If Japanese does not reach Level 2 or above, it will be difficult for Japan to find a job immediately even if the economic situation is good.
If you can get Japanese Level 2 and have three years of development experience, the first year is about 250,000-300,000 yen per month (depending on your level). Young people will probably share a house with others and share the rent of 40,000 to 50,000 yen per month. If you can save a little about 60 thousand to 70 thousand yen on water, electricity, gas and telephone bills every month, you can save the rest. In this way, you can save 1.5 million to 2.5 million yen in the first year, and you can earn more if you work overtime.
After the second year, if I work hard, improve my Japanese and technical level, become better at communicating with Japanese people and understand Japanese corporate culture, I can ask for a salary increase, and it is possible to increase my annual income by several hundred thousand to one or two million. Later, everyone was different, because everyone showed different abilities and adaptability, and maybe he could get an annual income of more than 5 million. A person's average annual income is almost 654.38+0.5 million, and the rest can be saved. The exchange rate is always changing, about150,000 to 200,000 RMB.
This is the answer to the first and second questions.
The third question, generally speaking, it is basically impossible to engage in part-time development without language ability, and there is absolutely no shortage of development talents in Japan. It is basically difficult to find a development job without a Japanese foundation. So I'd better learn some before I come back. Language depends on personal efforts. If you work hard, you should be able to do it for a year. The Japanese government also has free Japanese classes for foreigners. You can use them. But if you don't work hard, 10 is hard to say.
