GREEN x EXPO 2027 is set to run from Friday, March 19, 2027 to Sunday, September 26, 2027 in Saitama. Two commercial partnerships are confirmed: Water Stand as a Bronze Partner of the heat-countermeasures project, and a Moomin x Tunktunk merchandise line rolling out from January 2027.
GREEN x EXPO 2027 is the 2027 International Horticultural Exposition, scheduled to run from Friday, March 19, 2027 to Sunday, September 26, 2027. Its official mascot is Tunktunk. Coverage so far consists of two commercial partnerships rather than programming or site details.
The first partnership announced was a collaboration between Moomin and Tunktunk. Official licensed merchandise goes on sale beginning in January 2027, drawing on Moomin's stated value of respect for nature and the expo's theme. The lineup includes a mug, a plate, two handkerchiefs, and an eco bag, priced from 1,980 to 4,400 yen. The mug and plate arrive around January 2027; the remaining items follow in late February to early March 2027, with more items planned.
The second is Water Stand Co., Ltd., a Saitama City company that has signed on as a Bronze Partner of the expo's heat-countermeasures project. Water Stand will provide water supply spots at the event, aiming to refill reusable bottles rather than sell disposable ones. That tie-in connects the vendor's business to the expo's heat-countermeasures work.
Both deals are licensing or sponsorship arrangements. No details about exhibitors, programming, or ticketing appear in the coverage so far, and the two announcements do not reference each other.
