the average monthly income earned by international students enrolled in Japanese language schools from part-time work
was ¥157,000.
Meanwhile, the average monthly tuition fees at Japanese language institutions in Tokyo ranged from ¥60,000 to ¥90,000.
Combining living expenses and tuition fees totals between ¥161,000 and ¥191,000.
Therefore, it is evident that wages from part-time work alone after arriving in Japan are insufficient to cover these costs.
