Three Cretaceous sea stacks — the tallest 50 meters — standing where the 2011 wave passed. About 2 km (25–30 minutes) on foot, or 5 minutes by car, from Taro station.
- 5 hr door to door needs a 7-hour call: a 2–3 hour stop cannot hold it. Pick something closer instead.
- No single published ride covers this one. Budget for a taxi both ways, or fold it into a guided day.
Why Sanoiwa rocks is famous
Three sea stacks in a row, the largest about fifty metres, standing off a beach north of the town. The other two are about 23 and 17 metres. They are a prefectural Natural Monument (designated 1992) and, unlike Jodogahama, you usually have them to yourself. The shore path was damaged in 2011 and the city has posted no-entry notices on it, so check on the day which paths are open.
Sanoiwa rocks and your ship
Both pins on one map, so the distance is a fact rather than a feeling.

Each one is a finished day timed from the official timetables, with this stop in it. Read the route rather than assembling it yourself.
What to put beside it
Each of these still lands you back aboard with the hour to spare.
