South Korean venture Roadsystem completed a proof of concept for a blockchain-based decentralised identity (DID) mobile passport fast check-in service at hotels in Japan, laying the groundwork for entry into Japan’s tourism infrastructure market.

The trial was conducted in collaboration with DNP, the world’s largest comprehensive printing company, and USEN-ALMEX, which ranks No. 1 in market share in Japan for automated hotel settlement machines and kiosks. The service was operated at Japanese hotels for actual foreign customers.

The model was first discovered and validated in South Korea with support from the Seoul city government in 2025. It underwent a proof of concept at the MD Hotel in Seoul’s Doksan-dong, and was later expanded to Japan through the "2025 tourism companies overseas verification support programme" promoted by the Korea Tourism Organization and KTSC (Tokyo Tourism Support Center). It is also significant as a case in which technology verified under a regulatory sandbox pilot exemption by the Ministry of Trade, Industry and Energy was 이어진 to an overseas service.

The trial showed that mobile passport fast check-in integrates check-in waiting, lodging register preparation and passport scanning into a single mobile authentication process. It created a user experience in which foreign tourists can complete self check-in within 30 seconds. The hotel side also confirmed an effect in easing staffing shortages by reducing reliance on front desk staff.

Roadsystem plans to expand the service to more than 1,000 hotels across Japan in 2026 based on the proof of concept. The mobile passport is expected to be used as an authentication infrastructure that can be linked from check-in to the full tourism process, including payments, duty-free shopping and transportation.
