Rakuten Ichiba is its flagship online marketplace, connecting consumers with merchants across Japan and internationally. The company is known for integrating services through its membership and loyalty ecosystem, including Rakuten Points. Rakuten employs a diverse, international workforce and promotes English as an important business language in many departments.

The Osaka branch provides opportunities to work on major products while living outside Tokyo and collaborating with colleagues across Japan and overseas.
Japan is an island nation with strong opportunities in software engineering, cloud computing, data, robotics, finance, manufacturing, tourism, and international business. Tokyo has the broadest job market, while Osaka offers a lower-cost lifestyle, a major technology and commerce community, and convenient access to Kyoto, Kobe, and Nara. Japanese workplaces value punctuality, teamwork, respect, and attention to detail; international companies may use English, although Japanese improves daily life and career options. Residents enjoy excellent public transport, safety, varied food, seasonal festivals, and efficient healthcare. Housing and commuting costs are generally higher in Tokyo than in regional cities. Foreign professionals typically need an appropriate work visa, commonly the Engineer/Specialist in Humanities/International Services visa, supported by their employer. Candidates should prepare employment documents, verify qualifications, arrange housing, and register their address after arrival. Japan also offers highly skilled professional pathways for eligible applicants.
