Island Birthday Party is held once a month on the terrace of the Shima Kitchen, Teshima. Local people and visitors celebrate the people of the birthday month together. The party is open to all kinds of people, including the elderly who rarely have a chance to go out, children who live on Teshima, tourists who visited the island, and the Koebi-tai, a volunteer group who came to the island for this event. Since 2014, the Teshima Birthday Party has welcomed a variety of fun guests every year and has celebrated more than 300 people so far. In addition to the Shima Kitchen, we plan to hold a party at a different place each month.
