Nuwajima Island

Nuwajima is located west of the island chain. Most of the islanders have fishing licences and are involved both in agriculture and fishery. Various citrus fruits not only Mandarins, Iyokan, lemons but also Beni Madonna and Karamandarine are widely cultivated. Fishermen land wild sea bream and yellowtail. Abalone and seaweed are also farmed in the sea around this island. “Botchan Shima Awabi” is known as an abalone brand.
“Marukobana” and “Ikikijizouno Kusu” has legend and there is a temple and a shrine on the island.
The Kudako Current, where powerful tidal currents flow, is one of the popular fishing spots and visited by many fishermen.


The Cableway was formerly used throughout Kutsuna Island. Now that agricultural roads have been developed, Cableways are only found in a part of Nuwajima Island.
The Cableway is installed to send off mikan from high places of the mountain. Ships run with special loading containers for mikan during shipment time, and many cranes are prepared at the port. However, the island produces more mikan than the ferries can carry during busy seasons. Nuwajima Island is well known as a citrus production site.


A small round mountain named “Marukonohana” is located on the north east side of Kaminuwa port. According to “The legend of Maruko princess”, Maruko princess lost her life in a shipwreck on New Year’s Eve of the old Japanese calendar. The legend says that on this day, a fire will lit up on the surface of the ocean around Marukobana. In addition, “Jizo carved into a living camphor tree” was created by a traveling priest in 19th century. Legend states that if you worship and stroke a part of the Jizo, the same part on your body will be healed.

Kudako Island

An isolated island called “Kudako Island”, with a circumference of 1.8km, is located between the main island of Nakajima Island and Nuwajima Island. Kudako Island is in the center of a channel that is 154 meters underwater with a nautical mile width of 0.6. This channel and Tsurijima channel are both major sea routes leading from Akinada open sea to Iyonada open sea. A channel, especially on the west side, can reach a maximum current velocity of 6.5 knots. Seafood caught in the rough ocean current tends to have tightened meat and an increase in umami flavor. As a result, the Seto Inland Sea is well known for being the leading fishing industry, and pole-and-line fishing of sea bream is in full operation. The whole Kudako Island appeared to be a fortress, as a cliff on the south side became a rampart, and a citadel was created by skillfully taking advantage of the top of the geographical feature. The fortress was identified during the Nanbokucho period, and is thought to follow Motoyama Castle/Taizan Castle; however, the construction period and who it was built by is unknown.
