SUCRECUBE Japon

What SUCRECUBE Japon does

SUCRECUBE Japon Inc. is a Tokyo-headquartered social-infrastructure company that designs, assembles, and deploys off-grid solar power, communications, and cold-chain systems in West Africa under the TUMIQUI brand. The company's core hardware is the TUMIQUI Smart Kit — a portable, plug-and-play solar generator pairing an 864Wh NCM-lithium battery with a 180W monocrystalline solar panel and multiple AC/USB/DC outputs that runs TVs, printers, medical devices, and Wi-Fi routers without technical training. Around this it has built two scaled-up lines: TUMIQUI Power Digital Solutions (a fixed solar-plus-long-range-communications off-grid data center, with Senegal's first installed in 2022) and TUMIQUI Module (a modular container integrating solar generation, refrigeration, telecommunications, and a digital KIOSK into a single village-level value-creation hub). A fourth product, TUMIQUI Délices, processes Senegalese mangoes into purée for export to Japan and France in partnership with Okinawa-based Okipota. Underlying technology emphasizes tropical-environment resilience, CE certification, and integration of photovoltaics with lithium storage, long-range comms, and energy-efficient refrigeration co-developed with corporate partners including Daikin, Dai Nippon Printing, and Seiko Epson.

The company serves four primary use-cases: rural healthcare clinics (10 sites in Senegal serving over 80,000 residents for nighttime births, vaccine refrigeration, and digital reporting), schools (20 elementary schools in Senegal and 122 in Gambia via UNICEF, with documented exam pass-rate improvement from 31% to 77%), agricultural value chains (cold storage, post-harvest loss reduction, mango purée processing for smallholder farmers), and international organizations / border security (IOM's 45-unit adoption for The Gambia border management). Customers are governments (Senegal ministries of Health, National Education, and Industry & Commerce; Sandiara city), UN agencies (UNICEF Gambia, IOM), and Japanese conglomerates co-investing under METI's Global South co-creation program. The revenue model blends upfront hardware sales with a B2B rental layer, managed-services revenue from digital infrastructure, and emerging transaction-based income from processed agricultural exports — with FY2026 earmarked as full-scale commercial launch year for the Module and Délices lines.

SUCRECUBE Japon was incorporated on April 13, 2018 by CEO Koichi Sato, who previously founded and operated SUCRECUBE Technologies in France for over a decade. The group operates via Japanese parent (Tokyo, Chiyoda-ku), wholly-owned Senegalese subsidiary TUMIQUI JAPON SASU (Sandiara economic special zone, manufacturing/assembly/data center operations), and French subsidiary SUCRECUBE Technologies. Funding to date consists of a JPY 36M seed round (February 2021, Hinoki Co. lead) and a 2022 third-party allocation led by K4 Ventures (Kansai Electric Power Group corporate venture capital), supplemented by METI subsidy grants. The company holds multi-ministry MOUs in Senegal, partnerships with Kansai Electric Power Co. (2021-2022) and four major Japanese corporates (2025), and recognition including the 5th Japan SDGs Award Special Prize (2021) and 3rd Nikkei Social Business Contest Excellence Award (2019/2020).

Core offering

SUCRECUBE Japon Inc. designs, manufactures, and deploys off-grid solar power systems and integrated ICT infrastructure for unelectrified areas in West Africa, primarily Senegal. Its TUMIQUI portfolio includes portable solar kits, modular containers combining solar power with cold storage and digital KIOSK, and off-grid data centers. The company sells and rents these solutions to government ministries, international organizations (UNICEF, IOM, JICA), and Japanese corporate co-creation partners to power rural healthcare clinics, schools, and agricultural value chain infrastructure.

Product overview

SUCRECUBE Japon operates the TUMIQUI Project, a co-creative social infrastructure platform providing electricity and communication solutions across Africa. The portfolio consists of three core product lines: TUMIQUI Smart Kit (portable solar power units for healthcare and education), TUMIQUI Module (modular container combining solar power, refrigeration, telecommunications, and KIOSK functionality for agricultural cold chain), and TUMIQUI Délice (mango processing into purée for export). These products work together as an integrated ecosystem: Smart Kit provides foundational power access, Module enables cold storage and processing infrastructure, and Délice monetizes agricultural output through value-added processing. The company also offers TUMIQUI Power Digital Solutions as an umbrella service for fixed solar-plus-communication deployments.
