Tokyo Metro Launches Japan's First Crowd-Sourced Subway Inspection Pilot: A Game Born on Utility Poles Moves to 180 Stations and Tens of Thousands of Assets

What happened: passengers photograph lights and signs at three stations

The three companies will launch the pilot, titled "Watching Over Stations Together: Photograph the Lights and Signs," on November 14, 2026, running until January 17, 2027 between 10 a.m. and 4 p.m. each day. Targets are general lighting such as fluorescent and LED fixtures and guidance signage; restrooms, stairs, elevators, escalators and platforms are excluded. Participants install the PicTrée app, go to locations shown on the map, and photograph a sign plus four directions around it. Valid submissions earn in-app PicTrée reward coins, convertible to various point programs, plus roughly 5 to 15 Metpo points per location, Metpo being Tokyo Metro's own loyalty program. Metpo points are scheduled to be credited on the 11th of the second month after the event ends.

The problem: 9 lines, 180 stations, tens of thousands of assets

Tokyo Metro inspects tens of thousands of pieces of equipment across 9 lines and 180 stations every day. The pilot aims to detect minor issues such as unlit lamps or damaged signs earlier and speed up repairs. The release states explicitly that the program does not replace statutory or specialist inspections; it tests whether crowd-sourced images can support on-site checks, help prioritize targets and eventually allow partial labor savings for externally visible items. Images are transmitted through the app without being stored on participants' devices, encrypted, screened by GRG and DEA for bystanders, and then acquired and retained by Tokyo Metro under its privacy policy.

What PicTrée is: from utility poles to railways

PicTrée is a team-based game in which players photograph everyday assets such as utility poles and manholes and compete on volume and distance. TEPCO Power Grid began piloting it in Maebashi, Gunma in April 2024 and later extended it to central Tokyo, Numazu in Shizuoka, Hokkaido and the Tohoku region, with reported cases of early detection of tree encroachment and crow nesting on poles. GRG, the operator, was jointly established by DEA and Greenway Grid Global, a Singapore company in which TEPCO Power Grid is involved. DEA was founded in Singapore in 2018, built an economy around its DEP crypto asset, and has operated through a Japanese entity since January 2026. In 2026 PicTrée also ran a nationwide disaster-preparedness championship covering all 1,741 municipalities to map evacuation sites and equipment. In rail, a pilot at eight Oga Line stations in Akita, the first inside JR stations, runs from November 1 to 29, and Tokyo Metro follows as the first subway operator.

Reading the structure: distributing inspection cost and funding the rewards

The essence of the scheme is to take the "discovery" step of inspection, previously performed by patrolling staff, and distribute it to the public as a rewarded game. For the rail operator the appeal is that it gains a new data input, images, without changing its existing inspection regime. The reward budget, however, is borne by the operator, so the 5 to 15 Metpo points per location is also a test of whether labor savings justify reward costs. That DEA, a company that designed game economies on blockchain, now handles reward design and image quality control for a public-infrastructure task illustrates how Web3 firms can enter social infrastructure without putting a token in front of the customer.

1. Separating "discovery" of anomalies from "judgment" of anomalies allows part of a specialist process to be externalized. Tokyo Metro states it is not replacing statutory inspections, yet opens only the discovery step to the public. Proposals to infrastructure companies are more readily accepted when they identify which step can safely admit outside eyes and carve out only that step.
2. Linking rewards to an existing points ecosystem makes gamification work without exposing a token. Participants earn Metpo and PicTrée coins and never touch crypto. Given Japan's regulatory environment and corporate risk appetite, blockchain operators should treat placing their token behind the client's loyalty program as the default design.
3. The move from electricity to rail reuses the same template of visual inspection by photograph across industries. It took about two and a half years from the Maebashi pole pilot to the Oga Line and Tokyo Metro. Planning from the outset to roll a proven template across industries with similar inspection targets, such as roads, water, telecom and commercial facilities, lowers the sales cost per deal.
