I recalled what somebody expressed “ I thought it is an island, but it was a cape. I thought it is a cape, but it was an island”

You can imagine there are lots of islands in this area.

Murakami Navy is one of the things that were produced by such special terrain. Murakami Navy was the navy that allied with Mouri family.

Luís Fróis who visited Japan in the warring states period of Japan as a Portuguese missionary expressed Murakami Navy is a pirate who seized a valuable article indiscriminately from ships that was passing through their territorial waters.

However, in fact, it seems that they were pilotage that collected toll fee by guiding ships that tried to pass their territorial waters.

The oldest record of appearance of Murakami Navy is 1394. And it is seems that the record refer to they escorted at sea.

They took military action against ships that tried to pass through their territorial waters without not to comply with rules, so they might have been called a pirate.

Putting that aside, their military power was strong overwhelmingly.

Battle of Miyajima in 1555 is battle that Motonari Mouri who is expanding his territory in Chugoku region fought to hold supremacy. At the time Murakami Navy fought together with Mouri family against enemy. And they led Mouri family, which was overwhelmingly disadvantageous by the number of soldiers, to the victory.

Also, In Battles of Kizugawaguchi of 1576, Murakami Navy and Mouri family fight hard against Oda family to carry provisions to Ishiyama honganji Temple that was surrounded by Oda family. And then they accomplished their purpose.

As above, Murakami Navy taken an active part together with Mouri family, but Mori family went on declining after Battle of Sekigahara in 1600. As if in concert with that, Murakami Navy also went on declining.

Murakami Navy was one organization originally, but it branched into three families of “Noshima Murakami” “Kurushima Murakami” and “Innoshima Murakami”.

And then, there is an institution that has exhibited historical records regarding Murakami Navy in Innoshima Island where was the base of Innoshima Murakami formerly.

The name of the institution is “Innoshia Navy Castle” !
