One of the oddest places in Japan, the surreal Geibikei Gorge is a slightly decrepit, definitely kitchy tourist attraction. You board a gondola at the local river, and your gondolier will sing in classic Japanese style as he manuevers further into the echoey gorge. Your destination is an upriver sandbar, where you disembark for a stroll, and for a nominal fee you can throw kiln-fired clay divots into a crack in a cliff across the river (each divot has a character on it,
and if you chuck it in the hole, that fate is in store for you). Bring bread to feed the river fish—they aggressively follow the boat and jump for joy at handouts. Those fish are also available roasted and fried where you disembark. The trip takes 90 minutes, and gondolas leave at the top of the hour every hour. To get here, take a JR train from Hiraizumi to Ichinoseki (20 minutes), then change to the Ofunato Line to Geibikei (30 minutes).
