Background
GreenSnap has held the "Hanamiru Stamp Rally," guiding visitors around Yokohama's flower and greenery spots, each season, starting with the spring edition this past March and followed by the summer edition from July. The spring edition drew a cumulative 4,642 participants, and 88.3% of visitors photographed seasonal flowers, a strong response that led to the rally's continuation through summer and now autumn.
For this autumn edition, GreenSnap has kept the perennially popular Satoyama Garden and other nature spots on the route while adding "GreenSnap Marche YOKOHAMA 2026 AUTUMN," combining a walk around town with an event visit.
Highlights: A Spot Families Can Enjoy Together
Along with Yokohama's characteristic natural spots such as Yamashita Park and Satoyama Garden, the autumn edition adds "GreenSnap Marche YOKOHAMA 2026 AUTUMN" as a stamp spot. Pairing the rally with an event that families with children can enjoy lets participants create autumn memories not only while walking the city but also at the event venue itself.
Rewards
Participants who collect a set number of stamps receive Yokohama-inspired rewards, including an original eco bag from Kitamura Co., Ltd., a pin badge featuring past designs of "Garden Bear," the mascot of Garden Necklace Yokohama, and invitation tickets to Wonderia Yokohama, an immersive experience facility in front of JR Kannai Station.
Looking Ahead
GreenSnap has continued to run the "Hanamiru Stamp Rally" each season, spring, summer, and now autumn, as a way to discover the charm of Yokohama's neighborhoods throughout the year. The company plans to keep deepening its ties with the city's nature and events, including Satoyama Garden, through experience-based initiatives that combine plants with digital technology, contributing to both the floriculture industry and the appeal of the local area.
