Tenjō River天井川A river whose water flows higher than the surrounding land due to sediment deposited from the mountains. The director explained it during the Expedition Team event. It doesn't appear in the scenery, but Shinko may well have played in this river too. There are several such tenjo-gawa (elevated rivers) here, but their water volume was insufficient for rice paddies, so an irrigation channel from the Saba River was built in ancient times and is still in use today.
