Founded in 1997, it operates a broad ecosystem covering e-commerce, fintech, mobile communications, digital content, travel, advertising, and professional sports. Rakuten Ichiba is its flagship online marketplace, connecting consumers with merchants across Japan and internationally. The company is known for integrating different services through its membership and Rakuten Points programs. Rakuten employs a diverse, multinational workforce and commonly uses English alongside Japanese in many corporate and engineering teams.

Employees typically work in collaborative, fast-moving teams, with opportunities to contribute to products used by millions of people.
Japan offers strong opportunities in software engineering, cloud computing, data, finance, manufacturing, tourism, and international business, particularly in Tokyo, Osaka, Nagoya, and Fukuoka. The workplace culture values reliability, teamwork, preparation, respect, and continuous improvement, although communication styles can be formal and hierarchical. Daily life is generally safe, convenient, and supported by excellent public transport, healthcare, and infrastructure. Tokyo has high housing and living costs, while regional cities may offer a more relaxed and affordable lifestyle. Foreign professionals usually need an appropriate work visa, commonly sponsored by their employer, and should prepare educational records, a passport, and employment documentation. Japanese ability is helpful for administration and everyday life, though some international technology teams work primarily in English. New arrivals should arrange housing, resident registration, health insurance, banking, and tax procedures after arrival.
