Working in Japan

Japan offers strong opportunities in pharmaceuticals, biotechnology, healthcare, engineering, information technology, manufacturing and research, especially around Tokyo, Osaka, Yokohama, Kobe and Tsukuba. Workplace culture values punctuality, preparation, teamwork, respect for hierarchy and careful attention to quality, although international companies are often more flexible. Lifestyle varies from energetic metropolitan living to quieter regional communities, with excellent public transport, safety, healthcare and convenience services. Housing and commuting costs are highest in Tokyo. Foreign professionals normally need an employer-sponsored work visa, such as the Engineer/Specialist in Humanities/International Services or a highly skilled professional status, with qualifications and a formal job offer required. Employers commonly assist with immigration paperwork and relocation, but applicants should confirm tax, insurance and dependent arrangements. Learning everyday Japanese is highly recommended, even when English is used at work. Japan’s four main islands are Honshu, Hokkaido, Kyushu and Shikoku, alongside many smaller islands.
