The Second Division continued east, capturing the fortresses of Jongseong, Onsong County, Kyongwon County, and Kyonghung County, and finally arrived at Sosupo on the estuary of the Tumen River. There the Japanese rested on the beach, and watched a nearby volcanic island on the horizon that they mistook as Mount Fuji. After the tour, the Japanese continued their previous efforts to bureaucratize and administrate the province, and allowed several garrisons to be handled by the Koreans themselves.
