The solution
The year 2022 was the 150th anniversary of the opening of Japan's first railway, but it collided with the COVID-19 pandemic: mass events and live stamp rallies were impossible, and contact-averse riders had lost the habit and the emotional pull of train travel. The six JR companies (Hokkaido, East, Central, West, Shikoku, Kyushu) share the network but had only a one-year anniversary budget — no new line, no new fare, nothing to hand a rider that made a train ride worth taking again.
A conventional anniversary comms push could say 'the railway is 150' and show beautiful trains, but that is a message about the past, and it asks nothing of the rider that a fare already asks. JR needed a reason to ride at all, and across six rival companies on a shared network, that reason had to be open to every station on every line or it would tear the coalition apart.
Dentsu built 'MY JAPAN RAILWAY', a web app that mints a digital station stamp when your phone's GPS enters any of 1,063 eligible JR stations. A novelty wears off unless it feels owned, so the stamps were engineered like analog rubber stamps: color intensity wobbles faint-to-dark by how you press, and each records the date, time and press count of your visit. Riders are given a spanning collection to complete, so a trip to the city and a detour to a rural station now both bank a piece of a personal, all-of-Japan set that 50 work stamps and 18 seasonal stamps only enlarge.
What it achieved
Minted GPS-based digital station stamps at 1,063 stations, with analog-like press variation and date records, so riders collect a personal set that rewards riding more.
Why it worked
Stamps create a second ledger of completeness that encourages more rides.
The spanning set of 1,063 stations means no single trip completes it.
Faint-to-dark press detail makes digital stamps feel physically owned.
Shared platform lets six rival companies benefit without ceding lines.
What can be applied
When a network is underused and you have no new product, re-denominate routine use into a collectible that users complete.
Aftermath
Per the case's own figures: 1.8 million users and about 11 million stamps; the one-year campaign ran into its third year. JR Group kept the platform running past its anniversary into a third year, moving it from a web app toward a permanent layer across the network, and Dentsu has cited it as a proof that a railway's value can be carried by a digital collection rather than by the farebox alone.
