Using input-output analysis, we estimated the economic effects of utilizing Tama lumber in the renovation project of Tokyu Togoshi-Ginza station. Final demand of the project was estimated to be 12.970 million yen on the basis of an interview with Tokyu corporate employees and a field survey at the station. The production value of the economic effect was 30.267 million yen (10.130 million yen in Tokyo; 12.618 million yen in Fukushima Prefecture; and 7.519 million yen in other prefectures). The added value was 14.675 million yen (5.964 million yen in Tokyo; 5.136 million yen in Fukushima Prefecture; and 3.575 million yen in other prefectures). The new employment created in the Fukushima Prefecture wood industry was 0.75 and that in the Tokyo forest industry was 0.66. We concluded that the utilization of local wood in Tokyo had a greater influence outside Tokyo than it did in Tokyo. We recommended that the Tokyo government recognize the results positively to contribute to the national economy instead of regarding them as opportunity loss for Tokyo. It is important to evaluate the economic effects of local wood utilization by adopting a supply-chain-based approach.
