Lake Hamanako Guide

Hamanako (Lake Hamana), Shizuoka Prefecture 浜名湖

Lake Hamana (Hamanako) is just west of Hamamatsu, in Shizuoka prefecture, close to the eastern border of Aichi. Hamanako is Japan's 10th largest lake, with a surface area of almost 65 sq km.

Lake Hamana was once a fresh water lake but earthquakes and a tsunami in 1498 have made the water brackish.

Hamanako is a very popular resort area in summer for boat excursions on the lake and other water sports such as water skiing, kayaking, wind surfing, parasailing and, of course, fishing.

Hamanako is famous for its eel and oysters. Also, blowfish (fugu) and pike conger (hamo) are both caught off the Enshu Nada coast. The Hamanako region is also known for its delicious strawberries and mikan oranges, and visitors can pick and buy their own in a number of places near Mikkabi on the north-west edge of the lake.

Besides the local delicacies, Lake Hamana has a number of onsen hot springs, in the nearby towns of BentenjimaKanzanji and Mikkabi.

Kanzanji is home to a number of hotels and ryokan with hot spring baths, a fun fair - Hamanako Pal Pal - a ropeway up to Okusayama Sightseeing Platform, Kanzanji Temple, Hamamatsu City Zoo, Hamamatsu Flower Park and lots of places to pick your own fruit in season: mainly strawberries and mandarin oranges.

Kanzanji also draws wind surfers, sea kayakers and parasailing enthusiasts, especially in summer.

Hamanako Attractions


Due to its location adjacent to the historic Tokaido highway between what is now modern-day Tokyo and Kyoto, the Hamanako area has a number of sites dating from the Edo Period of Japanese history.

Near the coast, the original Arai Checkpoint (sekisho) is the only such extant barrier checkpoint station on the Tokaido. The historic Kinokuniya Inn is also close by and both places are short walk west from Araimachi Station.

From Bentenjima, one stop east on the JR Tokaido Line, visitors can see the beautiful Maisaka Shukuwaki-honjin, an inn for samurai and commoners traveling on the Tokaido, but used for more important people if the honjin - inns for daimyo, court nobles and Shogunate officials - were full. The honjin have rarely survived as they catered to such rarified clientele, whereas there are a number of waki-honjin still in existence in Japan, though the Maisaka Shukuwaki-honjin is the only such place left on the old Tokaido highway.

The Nakamura Residence is north of Bentenjima over the Ufumi Bridge and is the preserved household of a samurai family.

A short walk or shorter taxi ride from Mikkabi Station on the Tenryu Hamanako Line is the delightful Kamakura period (1192-1333) Makayaji Temple with its impressive Heian-style garden and trio of historic Buddhist wooden statues, two of which are classified as National Treasures.

Kanzanji Temple predates the onsen and some say it was founded by the famous priest Kobo Daishi (Kukai) in the 9th century.

Kanzanji Temple is a Soto Zen temple located on a small hill (Tateyama) behind the Sago Royal Hotel, and the temple grounds contain a large statue of Kannon - the Buddhist Goddess of Mercy - viewing spots over Lake Hamana and a cave, Ana-Daishi, where prayers can be said for healing of diseases of the eyes.

There are also some small shrines in the complex where supplicants can write ema - votive plaques - in the hope of finding a spouse or for happy marriage. The temple holds an annual fire festival on December 15.

To the west near Kosai city is the Sakichi Toyoda Memorial House, located at the birthplace of the founder of the Toyota company. The museum celebrates Toyoda's life as an inventor of power looms and the setting up of a company that was to become famous for automobile production. Toyoda's former home and shed, where he worked on his inventions, still remain.

Kanzanji Onsen on the eastern side of the lake dates from 1958 when a hot spring was discovered and drilled. A number of hotels and traditional Japanese inns (ryokan) were subsequently built, with extensive baths utilizing the hot water and providing beautiful views over Lake Hamana.

These hotels and ryokan include the Sago Royal Hotel, a resort-style hotel close to Kanzanji Temple, Ryokan Nakaya, Hamanako Grand Hotel Sazanamikan, the traditional Kaikakutei with outdoor and indoor baths, as well as the more budget Matsuichi and Naito - both Japanese-style with tatami-floored rooms.

The large bath complex Hanasaki-no-Yu, part of the Hotel Wellseason Hamanako, has three baths, a buffet restaurant, relaxation areas and a massage center.

Most of the onsen in Kanzanji are open to day visitors as well as guests staying at their respective hotels and ryokan.

Bentenjima, Yuto, Mikkabi and Oku-hamanako also have less well-known onsen.

Hamanako Pal Pal is a popular amusement park with a number of fun roller coasters, a Ferris Wheel, water rides and merry-go-rounds. The Hamanako Music Box Museum can be reached via the Kanzanji Ropeway over the lake from Hamanako Pal Pal.

Bentenjima, where the sea meets the lake, is popular with anglers and is pleasant place to stroll along the beach to see the torii gate (Symbol Tower) in the water and watch the sun set. Nagisaen Camp Site is here along with places rearing the area's signature food - unagi (eels). The totally flat reclaimed islands north of Bentenjima Station have some pleasant parks and a statue of Kannon - dedicated to people who fish for a living.
