Suruga Bay (駿河湾, Suruga-wan) is a bay on the Pacific coast of
Honshū in Shizuoka Prefecture, Japan. It is situated north of an
imaginary line joining
Omaezaki Point and Irōzaki Point at the tip of
Izu Peninsula and surrounded by
Honshū to the southwest and west
Izu Peninsula to the east.

Suruga Bay is a place of contrasts. Japan's loftiest peak, Mount Fuji
at 3,776 metres (12,388 ft), rises from the 2,500 metres
(8,200 ft) depth of the
Suruga Trough running up the middle of
the bay, which makes it Japan's deepest. Numerous rivers—especially
the major Fuji, the Ōi, and Abe rivers—empty into its western
portion, giving that area of the bay a seabed rich in submarine
canyons and other geographical features, whereas at the bay's
easternmost end, only the
Kano River empties into a pocket called
Uchiura-wan at Numazu, Shizuoka, where the
Izu Peninsula connects to
Honshu, giving the water greater transparency and leaving the seabed
largely flat except for a number of small rocky islands, some joined
to the mainland by tombolos. This seabed variety coincides with
coastline differences as well: The western and central sections of the
Suruga Bay coastline, roughly from
Shizuoka, Shizuoka to Numazu, are
characterized by sandy beaches such as those at Yuigahama and
Tagonoura, whereas the eastern and northeastern stretches from Numazu
down the southwestern coast of the
Izu Peninsula to Irōzaki, are
The bay is open to the Philippine Sea/
Pacific Ocean to the south, but
is mostly protected from oceanic waves by Izu Peninsula. This, coupled
with the seabed and water characteristics mentioned above, results in
conditions favorable to fishing, sailing, windsurfing, swimming and
research on deep-sea organisms. An undersea plateau at the bay's
southwest end, known as Senoumi, is especially well known as a rich
Suruga Bay was formed by tectonic subduction of the Philippine Sea
Plate and the
Eurasian Plate at the Suruga Trough, making it a source
of considerable seismic activity, and giving the bay its extreme
Ever since the post-war industrial boom of
Japan the bay has suffered
from severe industrial pollution. By 1970 local paper mills produced
so much that the small city of Fuji (1970 pop. 180,000) produced 2.4
million tonnes of waste water every day - equivalent to the daily
Tokyo at the time (1970 pop. 9 million). The sulphur-laden
sludge was so thick that it threatened to block the harbour, requiring
dredging that severely damaged the marine life. Protests from local
citizens and fishermen in the area put pressure on the government to
take action. Despite subsequent regulations, surveys of local sea
life in the mid-2010s continue to show intense PCB and PBDE
The pollution of
Suruga Bay became so infamous that it featured in the
1971 film Godzilla vs. Hedorah. The name of the titular monster is
derived from hedoro, the Japanese word for 'mud', and the creature fed
off heavy pollution in the bay.
Suruga Bay can be reached by car from
Tokyo via Numazu in two to five
hours depending on traffic conditions on the
Tōmei Expressway or in
