Business Development

Belong operates smartphone resale, purchasing and rental businesses as an internal startup of Itochu Corporation. This role is part of the Partner Business Division, which works with major companies in telecommunications, distribution, retail and manufacturing using reused devices as a business asset.

The position develops business beyond conventional device supply. It proposes medium- and long-term business models to major domestic telecom carriers and primary agents, identifies their management challenges, and combines Belong's assets with partner resources to design and build schemes that maximize mutual benefits. The role also covers practical design of recovery and sales systems for distribution networks handling tens of thousands of devices. Responsibilities include interpreting market practices, resolving uncertain operational issues, and establishing and advancing effective processes.

The role pursues business growth with awareness of profit and loss responsibility, rather than focusing only on sales volume. Partner needs and market trends gathered on the front line are fed back to product development teams and other internal functions to improve the value of the services. The position also involves coordinating internal and external stakeholders, moving projects forward, and building and maintaining relationships with partner contacts from operational teams through management.

Examples of partnerships described in the posting include connecting Amazon.co.jp product and sales pages with Belong's consumer smartphone purchasing service, providing an online smartphone and tablet purchasing platform through BOOKOFF's service site, and expanding the purchasing service to hundreds of K's Denki mobile-related stores.

During the first six months, onboarding includes on-the-job training, accompanying existing partner visits, learning telecommunications business practices and Belong's business model, and handling part of a project’s distribution operations and issue identification. From six months through the second year, the role leads strategy for deeper partnerships, designs new distribution schemes, and coordinates product development and logistics teams on service improvements and new features. From the third year onward, possible responsibilities include proposing new businesses from the ground up, leading a unit and developing team members, and driving global expansion or larger alliances using the trading company's network.

The stated work location is Belong's Tokyo headquarters in Akasaka, Minato-ku. The office is scheduled to move to a new location near Aoyama-itchome Station around autumn 2026, with work continuing at the current location until the move. The selection process consists of document screening, two or three interviews with a reference check, and an offer meeting.
