This shows how land readjustment was promoted before the War, that is, the process from the organization to the dissolution of the association. Moreover, it shows that the private developers exsited in Suminoe District and how the housing management was. They persuaded the landowners and organized the association. They obtained a great deal of land in advance for the purpose of housing management. It was Mr. Gensuke TAKENAKA, the second president of Takenaka Shoten Co. Ltd., that organized the association. He established Takenaka Suminoe Tochi-bu and started the housing management. He sold and rented the houses and land. But he didn't succeed in selling the houses, so he engaged in renting the houses. Tujiei Jyutaku Keiei-bu participated in the association as well as Takenaka Shoten Co. Ltd. Tujiei Jyutaku Keiei-bu managed mainly the houses and land for rent. Both Takenaka and Tujiei managed over 100 houses with architects. The homes introduced the new idea of a residential housing.
