Following the battle of Sekigahara, the city of Obama was no longer only a port town, but also a prosperous castle town. This came with the suffering of the people of Kumagawa due to raised land taxes and the untimely death of Shozaemon Matsunoki, but it also brought a cultural boom due to the coming and going of cargo ships. You can see the results of this cultural exchange here at Furukawa-ya Goshōen.
