High schools generally offer a three-year program, which Evening high schools and correspondence courses offer programs for more them three years. There are several types of high schools.
- General academic high school
- Specialized high school that targets future employment in a specific job area (such as agricultural high school, industrial high school, commercial high school, etc.)
- Technological colleges (kosen)
Combined with college-level education, technological colleges in Japan offer a five-year program to students who wish to gain greater technology-related skills. The specialized areas of technological colleges include industry, merchant marine-related studies, electronic/information engineering and aviation (At present, there are no technological colleges in Tokyo for merchant marine-related studies or electronic/information engineering). Graduates of technological colleges go directly into employment or continue their education at university.
- Evening classes/correspondence courses
Some high schools offer evening classes or home correspondence courses for those who work during the daytime and vice versa, and wish to receive a high school diploma. The classes and courses allow once-truant students and dropouts to learn at his/her own pace.

- Those who do not hold a high school diploma need to take and pass a qualification test (commonly known as daiken) to be eligible for universities' admission exams.
- Junior colleges offer a two-year program, while universities offer a four-year program. Junior college/technology college graduates may transfer to a four-year university course as a junior student. University graduates who wish to further study in their specialized area may choose to continue their education to graduate school. Master's programs offered at graduate schools are usually a two-year course.
