What impression do you have from the word "pirate"?
You probably imagine plunderers or gangs on ships.

The Murakami kaizoku, who 16th century’s missionary Luís Fróis called "the greatest pirates in Japan”, were based in the Seto Inland Sea. They consisted of three families based in Noshima, Kurushima, and Innoshima, and had a strong sense of kinship with each other even though they repeatedly collaborated and separated during the Warring States period. They were also well aware of the unique currents and topography of the Seto Inland Sea and were said to have played an important role in protecting the safety of the sea in the region. Moreover, the pirates have an intellectual and cultural dimension that cannot be summed up in a single word.

There are many remains related to the Murakami kaizoku on islands of Shimanami, which stretch from Hiroshima to Ehime, and have been designated as a Cultural Heritage of Japan. Oshima Island in Ehime is also one of the sites associated with the pirates. Based on Oshima, this guided tour follows the history of the Murakami pirates, who ruled the Seto Inland Sea from different aspects.

The site of Noshima Castle, where the tour starts, is the base of  Noshima Murakami one of the three Murakami pirates.
When you hear castle, you probably think of some magnificent building. However, there isn’t anything like that here.
This was called umijo, and the island itself was regarded as a castle.
Visit this rare sea castle that is unprecedented in the world!

Around Noshima, a tide of up to 10 kts (18 km / h) swirls.
For this reason, the sea around Noshima, in the middle of the Seto Inland Sea, was said to be both a strategic point and a difficult place for maritime traffic.
Enjoy cruising through the tidal currents to the ruins of Noshima Castle!
When you land on the ruins of Noshima Castle, a local veteran guide will guide you around the island. Enjoy imagining what it was like back in the day!

After that, we will visit the MURAKAMI KAIZOKU Museum.
When did the history of Murakami pirates begin?
Your guide will explain their stories that have been passed down through generations in an easy-to-understand manner while observing the exhibits.

For lunch, you can enjoy horaku-yaki, which is said to have been eaten by Murakami pirates to celebrate the victory.

Horaku-yaki, which is an unglazed bowl topped with fish and shellfish caught in the Seto Inland Sea, has an impact and is exquisite!
It is also said to be a dish associated with the Murakami pirate's weapon horakutama.
(* If you would like Western food, please contact us at the time of booking.)

After enjoying lunch, you will head to the final spot, Mt. Kiro.
Here, you can overlook the beautiful scenery of the islands of the Seto Inland Sea, which the Murakami pirates have been protecting for generations.
From the Kirosan Observatory, you can see the ruins of eight Murakami pirate castles! 

From the top to the foot of Mt. Kiro, ride an E-mountain bike and enjoy an exhilarating downhill!
This is the end of the tour.
If you find out about the truth of the Murakami pirates on this trip, you will surely want to share the story with your family and friends.

* You can optionally visit Oyamazumi Shrine and Treasure Museum on Omishima. (Tour time is extended by 120 minutes)
At Oyamazumi Shrine, many traces of the cultural aspects of Murakami pirates, such as horaku renga and teaware, and the weapons dedicated by Murakami Takeyoshi are preserved and exhibited.
