SCSK Deploys "Personal-Data-Free" NFT Tourism DX at Shurijo Castle — Sumitomo-Group SIer Attacks Overtourism and Dispersal in a Single Architecture

#### Core of the Announcement — Using NFTs to Solve Overtourism SCSK (headquartered in Koto-ku, Tokyo; President Takaaki Toma) announced Connexia on April 22, 2026 — a cloud service combining a smart-device web app with a one-to-one marketing system that requires no personal registration. At Shurijo Castle Park, neither app download nor personal data registration is needed: digital medal-style NFTs are distributed in response to visits, exploration of surrounding areas, and event participation. NFTs serve as a "proof of visit" held permanently on-chain and can carry utilities such as discounts at surrounding facilities and exclusive event access. Without collecting names or contact information, visit frequency, tour areas, and preferences are made visible purely through NFT holding history, feeding targeted engagement programs. #### Context — Seiden Completion Autumn 2026 and the Overtourism Alarm The Shurijo Seiden main hall, destroyed by fire on October 31, 2019, is scheduled for completion in autumn 2026 — the protective scaffolding was removed in October 2025, revealing the exterior publicly for the first time in about six years. Okinawa Prefecture is projected to set a record with over 10.87 million visitors in 2025, exceeding even pre-pandemic 2019 levels. Seiden's internal capacity is limited to roughly 200 people, and the prefecture has already announced time-slot reservation tickets as a physical control measure. SCSK's Connexia complements this with an economic-incentive-driven dispersal mechanism. SCSK signed a "Partnership Agreement on DX for Shurijo Reconstruction" with Okinawa Prefecture in June 2021, building this initiative over nearly five years. #### Japan's NFT Tourism Landscape and Connexia's Differentiation Japan has already seen multiple NFT-tourism implementations: the Osaka-Kansai Expo's "EXPO 2025 Digital Wallet" using SBTs, JNTO's "Japonism Moment" ink-painting NFT series launched April 2025 across ten regions, "ECHIZEN Quest" from JTB, Fujitsu, and Toda Corporation in Echizen City (field trial Nov 2025 – Jan 2026), and per BEINCRYPTO, over 17 local governments issued NFTs by August 2025. Yet as *Unseen Japan* noted, international tourist awareness of and demand for NFTs remains in question. Connexia differentiates on three axes: (a) an architectural stance of "NFT holding = anonymous ID," achieving full compliance with Japanese privacy law and GDPR; (b) zero-friction UX requiring no app download or wallet setup; (c) operational delivery by a Sumitomo-group, TSE Prime-listed major SIer — not a Web3 startup. #### Expansion Strategy SCSK envisions rolling out from Shurijo to other Okinawa tourism facilities, municipalities, and tourism associations, and ultimately to other regions nationwide. Longer-term, the company intends to port its "personal-data-free crowd orchestration" capabilities to social-problem domains beyond tourism. ## [Business Development Insights] 1.
