Shirahama Submarine Observation Tower (白浜海中展望塔(コーラルプリンス))


Observatory / Outlook

This all-weather observatory is about 100 meters off the coast from Hotel Seamore and about 20 minutes by car from Shirahama Station. About 18 meters high and stretching 8 meters under water, you can observe about 30 kinds of fish including black porgies and largescale blackfish from its 12 windows. The air bubbles rising from the sea bed are said to be where a hot spring comes to the surface. A picture panel of the fish you'll see will help you identify them. The observation tower has a pleasant breeze and a great view that looks out to the vast stretch of the horizon.

Im being generous with 4 stars here, but hear me out. This tower is an outdated oldschool remnant of the better days of this seaside resort, but it still holds some value.

Its 800 yen to get in and you
Go down stairs underwater perhaps 4-5m down. The portholes are a bit dirty and its interesting for perhaps 10 mins at most.
However the upper deck is air conditioned...

          Wakayama prefecture unites pilgrims, food lovers, and culture buffs in a tranquil corner of Japan at the base of the Kii Peninsula. The setting for many a Kumano Kodo pilgrimage trail, Wakayama invites those in search of spirituality from one side of the prefecture to the other, from the 100-plus Buddhist temples of the sacred Mount Koya in the west to the inspiring temples of the Kumano Sanzan set among breathtaking nature in the east. Once the grueling hike is complete, make a beeline for Wakayama city to savor some of the country’s most delicious ramen noodles.
