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

service
Japan Wireless

A pocket Wi-Fi device rental service targeting mainly inbound travelers to Japan. Strengths include multilingual customer support and digital marketing for foreign customers, but demand is structurally declining due to the trend shift toward eSIM.

service
Guro Moba

Sales and referral service for physical SIM cards and eSIMs. eSIM's appeal lies in its online-completion convenience, allowing application and activation entirely online, and eSIM usage expanded during the current interim period. On the other hand, rising procurement costs associated with increased eSIM transaction volume have become a challenge.

product
Mobile Accessory Sales

Sales service for mobile accessories accompanying Wi-Fi rental and SIM sales.

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
