Rakuten Group, Inc. is a major Japanese technology and internet services company headquartered in Tokyo. Founded in 1997, it operates a broad ecosystem covering online shopping, travel, digital content, fintech, banking, securities, mobile communications, advertising, and professional sports. Its best-known service is Rakuten Ichiba, one of Japan’s largest e-commerce marketplaces. Rakuten serves customers and businesses in Japan and international markets, connecting many services through its membership and loyalty ecosystem. The company has a diverse, global workforce and places strong emphasis on software development, data, mobile technology, cloud infrastructure, and innovation. Employees typically work in multicultural teams, with English widely used in many technology departments, while Japanese remains important for some business communication and daily life.
Japan offers strong opportunities in software engineering, e-commerce, finance technology, cloud services, data, robotics, and network operations, especially in Tokyo, Osaka, Kyoto, and Fukuoka. Workplaces value punctuality, quality, teamwork, and attention to detail, although international technology companies often use English and encourage flexible working styles. Japan combines excellent public transport, reliable infrastructure, safe cities, rich food culture, and varied lifestyles from busy urban centers to quieter coastal and rural areas. Osaka is known for its friendly atmosphere, lower living costs than Tokyo, and convenient access to Kyoto, Kobe, and Nara. Most foreign professionals need an appropriate work visa, commonly an Engineer/Specialist in Humanities/International Services visa, usually supported by the employer. Applicants should prepare education and employment documents and arrange housing, banking, health insurance, and residence registration after arrival. Learning basic Japanese is strongly recommended for daily life.
