Working in Japan

Japan offers strong opportunities in software engineering, cloud infrastructure, cybersecurity, data, finance technology, robotics, and digital services, particularly in Tokyo, Osaka, and Fukuoka. Workplaces often value punctuality, teamwork, careful planning, and respect for hierarchy, while international technology companies may have more flexible and English-friendly cultures. Daily life is generally safe, efficient, and convenient, with excellent public transport, healthcare, and varied food. Tokyo is highly connected but expensive; regional cities offer lower housing costs and a quieter lifestyle. Foreign professionals usually need an appropriate work visa, commonly sponsored by their employer, such as an Engineer/Specialist in Humanities/International Services visa. Relocation normally involves securing housing, registering residency, arranging health insurance, and obtaining a residence card. Learning basic Japanese is helpful for administration and everyday life.
