All in all there are four holes on the big rock.
Originally to collapse what was limestone cave, it is the layer where it remained at the top became a natural bridge.

Fourth Iwaana is so back area is also 300m, but only entrance looks.

Walk the mountain road from the parking lot about 5 minutes, it is located in the place where it was down the stairs.

When I went to ten years ago there was no such observatory, it seems now been developed.

The parking lot has pretty even managed rest areas and toilets.

Since a 10-minute drive from Maki-do Cave, if there is a chance to go to Maki-do Cave, I think that it is good to try by all means stop by.

In addition, since the taishaku valley in the eastern part of Hiroshima Prefecture, there is a splendid natural bridge, also there who are interested here by all means.
