Oshima, located on the Shikoku side of the Shimanami Kaido in Imabari City, Ehime Prefecture, is an attractive spot filled with history and nature. We will introduce you to the particularly noteworthy Nojima Castle Ruins, the only sea castle ruins in Japan, and a cruise around the castle where you can experience the powerful currents.
Oshima, located on the Shimanami Kaido in Imabari City, Ehime Prefecture, is an attractive spot filled with history and nature. In particular, the ruins of Noshima Castle are attracting attention as the only castle ruins on the sea in Japan. This castle ruin was once famous as a pirate base, and since it can be accessed from the sea, you can land by boat and experience its historical heritage up close. Of particular interest is the cruise that allows you to land on Japan's only castle on the sea and experience the powerful currents.
In this article, we will introduce the appeal and fun of the Nojima Castle ruins and tidal current cruise.
There are two types of cruises: one that requires a reservation and allows you to land on Noshima, and one that is just a cruise to experience the currents and does not include landing on Noshima.

If you are traveling by car, head to the Murakami Pirates Museum, about 5 minutes from Oshima Kita IC from Onomichi, or about 15 minutes from Oshima Minami IC from Imabari. The reception desk is located in the building facing the sea, "Nojima Suigun: Seafood Direct from Farm, Pier, Restaurant" in front of the Murakami Pirates Museum.
A guide from the local guide club will also board the boat for the landing tour. After everyone checks into their life jackets and uses the restroom (there are no toilet facilities on Noshima), we head to the pier and depart on the "Kojin Maru," a 64-person tourist boat anchored on the right. There is a best time for the tides. The times change daily, and can be checked on the tide table below.
The boat heads to Kojin Seto, a rapids spot around Noshima. The captain, whose steering skills are on par with those of a pirate, navigates the boat dynamically along the edge of the reef. You'll get to see the currents up close, which will make you wonder if you're really in the Seto Inland Sea. If you stop the engine, the boat will be swept away with such force that it's almost like going down a rapids river.
We finally land on Noshima from the private pier! We start our walk on the southern flat land while listening to the guide's explanations. Noshima has well-maintained promenades and is very easy to walk on. However, please be careful as there are some places on the gentle slope where there are no handrails. From Noshima, you can also see the Oshima Bridge that connects Oshima and Hakatajima.
According to the guide, 10,000 pieces of "kawarake" (tiles) were discovered at the site of the main citadel! Amazingly, small pieces of pottery can still be found here and there today... Feeling the rapidly changing currents and the pleasant breezes, we can reminisce about times gone by.
Access is 2 hours 30 minutes from Hiroshima Bus Center or 1 hour from Fukuyama Station (express bus), get off at Oshima BS.
For taxis, Oshima Taxi can be reserved for your convenience (Oshima Taxi: 0897-84-2629). Please tell them your destination is Murakami Kaizoku Museum or Nojima Suigun.
Tour participants will receive a "Castle Seal" as a souvenir. At the museum shop "Jiba Cafe Noshima", there is a wide selection of souvenirs from the Shimanami Kaido and pirate goods that can only be found here.
Noshima, with a circumference of about 850 meters, is designated as one of the 100 most famous castles in Japan, and its appearance as a sea castle can be clearly seen from its exterior. The Noshima Castle Ruins Landing & Tidal Current Cruise is a recommended activity that allows you to experience both historical exploration and the power of nature at the same time. Be sure to enjoy it together with the Murakami Kaizoku Museum!
