On Saturday, October 25th and Sunday, October 26th, 2025, the seminar of Lisa Nagai, Senior Assistant Professor the Department of Faculty of Economics, Department of Economics, Teikyo University, served the TFT*2 menu "Izu Oshima Island Sushi-style Chirashi Sushi" at the university festival "Seisha Festival" on Hachioji Campus as part of a"joint project between the Tokyo Metropolitan Government and the university" *1.
The joint project in which Nagai's seminar is participating, "Local Industry Creation Project Utilizing Idle Greenhouses - Passing on Oshima's Resources to the Next Generation," has been selected as a "Joint Project between Tokyo Metropolitan Government and Universities" for fiscal year 2025. The University of Electro-Communications is the representative of this joint project, with participation from Tokyo University of Agriculture and Technology, Tokyo University of Foreign Studies, and Nagai's seminar at our university. By utilizing idle greenhouses and combining advanced cultivation and digital technologies, the project aims to achieve stable production of fresh pepper, a high-value-added food ingredient. Furthermore, the project will promote the creation and branding of local industries by verifying farming models at shared farms and developing menus using Oshima's agricultural products.
Nagai's seminar has been working on developing menus using agricultural products from Oshima, and this time they offered chirashi sushi made with Oshima's island nori seaweed and bekko soy sauce, combined with TFT, a core initiative of the seminar, and sold 208 servings over the two days of the Seisha Festival. Nanae Hosogai (3rd year, Faculty of Economics) commented, "For this year's Seisha Festival, we wanted to use ingredients from Oshima and provide many people with a colorful menu, so we proposed chirashi sushi. We had a hard time adjusting the cost rate of the ingredients, but the support of my seminar members gave me the push I needed. I was happy to see people of all ages, from young children to the elderly, looking at the chirashi sushi posters on the day. As a result, many people purchased it and we were able to achieve our sales target."
Nagai's seminar will continue to work on promoting joint projects.
