For the past 25 years, Japan has been in an ongoing struggle with the proliferation of illicit part-time jobs, often referred to as "Yami baito." These unauthorized work opportunities, often affecting underage workers, have been a persistent problem. In response, Japanese authorities have issued over 70,000 warnings in a bid to deal with the issue.

The issue of "Yami baito", or illegal part-time jobs, has attracted grave concern in Japan. Many of these positions are filled by underage workers, exploited for labor and exposed to dangerous working conditions. They're often promoted online, a fact which heightens their allure but also increases their potential harm. Japan's societal values emphasize the welfare and upbringing of its youth, which makes this issue particularly pressing.

In the US and EU, child labor is also illegal, though there are circumstances allowing for part-time work with restrictions on hours and types of work, with explicit regulations in place. Illicit labor is fought against and harsh penalties are imposed for any violations. However, in contrast to Japan, the digital promotion and recruitment for such jobs might not be as prevalent.
