Business Details
Provides Wi-Fi device rental services (Japan Wireless), SIM card/eSIM sales and referral services (Guro Moba), and Mobile Accessory Sales primarily to inbound travelers to Japan (mainly from Western countries) and domestic corporate customers. Strengths include a multilingual customer support system and digital marketing know-how for foreign customers, achieving UI/UX localized for each country. The cost structure has a high proportion of fixed costs, including communication expenses and depreciation, such that improvements in utilization directly impact profitability.
Recent Overview
While eSIM expanded, Wi-Fi rental declined, and segment profit remained low at ¥5 million
In the interim period of FY2026 (ending September 2026) (October 2025 to March 2026), eSIM usage expanded while Wi-Fi device rental declined. As a result, net sales were secured at ¥726 million, but segment profit was limited to ¥5 million. As the service trend shift toward eSIM continues, rising procurement costs and the burden of fixed costs continue to weigh on profitability.
Key Products
Growth Drivers
- Expansion of Wi-Fi rental and eSIM demand driven by the increase in the number of foreign visitors to Japan (21.71 million over the six months from October 2025 to March 2026)
- Expansion of eSIM service usage: the online-completion convenience without the need for a physical device is appealing, with marketing efforts focused accordingly
- Brand strength based on appeal to customers from various countries through multilingual support and localization, and high customer satisfaction
- Fixed cost leverage effect from improved mobile network utilization (a cost structure with a high proportion of fixed costs such as communication expenses and depreciation)
- Further revitalization of the inbound market driven by global events such as Expo 2025 Osaka, Kansai, Japan
Risks
- Structural decline in demand for Wi-Fi device rental due to the service trend shift toward eSIM
- Pressure on segment profit due to rising procurement costs associated with increased eSIM transaction volume
- Increase in advertising expenses and sales commissions due to new entrants and intensifying competition
- Foreign exchange risk (foreign exchange losses recorded as non-operating expenses)
- Risk of profit pressure when utilization declines, due to the high proportion of fixed costs related to Wi-Fi device and communication procurement
