AIR-U

What AIR-U does

AIR-U Co., Ltd. (株式会社AIR-U) is a Tokyo-based mobile connectivity provider founded January 12, 2017 and listed on the Tokyo Stock Exchange TOKYO PRO Market (ticker 525) since November 2022. The company's core technology is a proprietary cloud-SIM platform paired with its CLOUD AiR-WiFi application, which enables mobile data connectivity without a physical SIM card across domestic Japan and 134+ countries/regions. Product portfolio comprises six mobile Wi-Fi routers — AIR-1 (3,000mAh, ~17h operation), AIR-2 (5G, 5,400mAh, ~40h, up to 16 simultaneous connections), AIR-3 (touchscreen, automatic 4-carrier selection, Wi-Fi relay), AIR-tra1 (IP54-rated, with 54+ language translation), and AIR-Stick WiFi (battery-free, USB Type-C, Wi-Fi 6) — plus ATab-1, Japan's first cloud SIM-equipped 10.1-inch GMS-certified Android tablet (launched July 2021), and the Pocket SIM for JAPAN prepaid SIM line including IoT SIM variants.

The business model blends five revenue streams: subscription mobile data plans for domestic Japan use; subscription international data plans (134+ countries); hardware sales of the AIR-series routers, ATab-1, and prepaid SIMs; channel/agency commissions from a recruited sales-agent network (代理店); and B2B2C distribution via Examobile for individual ATab-1 subscriptions and Bebot (BeSpoke) for inbound tourist support. Go-to-market is predominantly field-sales-led direct B2B into Japanese enterprises, municipalities, and boards of education — most visibly through the GIGA School digital-education initiative — with agent and partner channels extending reach. Distribution is single-country (Japan-domiciled) with global service reach achieved through the cloud-SIM architecture rather than physical infrastructure. Two telecom-relevant registrations anchor compliance posture: a Telecommunications Business Act registration (number A-29-15742) and ISO/IEC 27001:2022 certification (registration IA240044, initial certification April 11, 2024).

Government and institutional customers (municipalities, boards of education) are prominent customers, supplemented by enterprise buyers, inbound international travelers, and short-term visitors. The company holds no subsidiaries, has no disclosed parent, and has not reported revenue or headcount in the provided source material. Operationally the company is small-scale and Japan-domiciled: a single Tokyo head office (relocated December 18, 2023 to Minato-ku, Kita-Aoyama) staffed by a lean leadership team headed by President and Representative Director Kensuke Tanaka (田中 康之助), with three additional inside/outside directors and three outside auditors.
