hikikomori

The Japanese Ministry of Health, Labour and Welfare defines hikikomori as people who refuse to leave their house, and isolate themselves from society in their homes for a period exceeding six months. While the degree of the phenomenon varies on an individual basis, in the most extreme cases, some people remain in isolation for years or even decades. Often hikikomori start out as school refusals, or futōkō (不登校) in Japanese (an older term is tōkōkyohi (登校拒否)). The Ministry of Health estimates that approx. 50,000 hikikomori live in Japan, about one third of which are aged 30 and older (Larimer 2000)

apa itu NEET

NEET is a government initialism for people currently "Not in Education, Employment, or Training". It was first used in the United Kingdom but its use has spread to other countries, including Japan, China, and South Korea.

In the United Kingdom, the classification comprises people aged between 16 and 24 (some 16 year olds are still of compulsory school age). In Japan, the classification comprises people aged between 15 and 34 who are unemployed, not engaged in housework, not enrolled in school or work-related training, and not seeking work. The "NEET group" is not a uniform set of individuals.
