A collaboration campaign bringing together Tenryu Hamanako Railway, virtual singer Otomachi Una, and the location-based game series Station Memories! is set to get underway on April 21, 2026. Titled "10th Anniversary! Ride the Tenryu Hamanako Line with Otomachi Una and the New Unapippi Go!♪ Tenhamansen Travel," this marks the second installment in the ongoing Tenryu Hamanako Railway × Otomachi Una × Station Memories! series collaboration.
Campaign Overview
The campaign centers on a digital stamp rally that takes players to stations and tourist spots along the Tenryu Hamanako Railway. Completing all missions rewards participants with an exclusive in-game collaboration film featuring Otomachi Una.
