Participate in Forest Creation through the 'ODEN Stool'! Starbucks x Kirishima Shuzo x Miyakonojo City x more trees Complete New Scheme for 'Miyakonjo Resource Circulation Forest Project (ODEN)'

Starbucks Coffee Japan, Ltd., together with Kirishima Shuzo Co., Ltd., Miyakonojo City (Miyazaki Prefecture), and the general incorporated association more trees, announced the completion of a new scheme that allows people to participate in forest creation through the 'ODEN Stool,' part of the 'Miyakonjo Resource Circulation Forest Project (ODEN)' that has been underway since 2025.

New Initiatives for the 'Miyakonjo Resource Circulation Forest Project (ODEN)'

Prior to the opening of 'KIRISHIMA GREENSHIP icoia,' Starbucks and Kirishima Shuzo have been conducting experiments to create compost using coffee grounds and shochu lees as materials, with the cooperation of professors and students from the Department of Environmental Horticulture at Minami-Kyushu University, aiming for regional natural circulation. Since December 2025, they have collaborated with local forest creation efforts promoted by Miyakonojo City and more trees. As part of the 'Miyakonjo Resource Circulation Forest Project (ODEN),' they have been using the completed compost to cultivate seedlings of Japanese evergreen oak (acorns) collected within Miyakonojo City on the grounds of 'KIRISHIMA GREENSHIP icoia.'

Now, a new scheme has been completed that allows people from afar to participate in this project. Those who sympathize with local forest creation can participate by purchasing a stool with the same specifications as those used in the 'KIRISHIMA GREENSHIP icoia' seating area. This stool is made from Japanese evergreen oak from Miyakonojo, just like the ones in the store, and crafted one by one by artisans. Named the 'ODEN Stool,' it symbolizes this activity and is available on the official more trees website. Users can feel the warmth and gentle texture of the local wood, and a portion of the sales will be used for forest creation in Miyakonojo City. Through purchasing the 'ODEN Stool,' people can participate in Miyakonojo's forest creation from their daily lives, helping to nurture future forests while using wood in their own homes.

Acorn Cultivation and Forest Creation at 'KIRISHIMA GREENSHIP icoia'

Last December, members from Starbucks, Kirishima Shuzo, Miyakonojo City, more trees, and Minami-Kyushu University's Department of Environmental Horticulture began experiments to germinate and grow seeds (acorns) such as Japanese evergreen oak collected in Miyakonojo using compost made from coffee and shochu grounds. This spring, on April 26, 2026, about 30 participants, including customers, local companies, and students, joined a compost club workshop to transplant the sprouted acorn seedlings. About 150 seedlings have sprouted, ranging from those that have already grown to about 10cm to those that have just sprouted, and they are being nurtured on the grounds of 'KIRISHIMA GREENSHIP icoia' and at Minami-Kyushu University. They are being carefully raised with the goal of planting them in the forests of Miyakonojo next spring. Regarding the cultivation of these acorns, they plan to collect seeds such as Japanese evergreen oak in Miyakonojo this autumn and cultivate a second batch of seedlings using compost made from coffee and shochu grounds with the participation of local residents.

The 'Miyakonjo Resource Circulation Forest Project (ODEN)' will continue to work on building rich regional forests in collaboration with Starbucks, Kirishima Shuzo, Miyakonojo City, and more trees, while involving local residents.
