At the northernmost of the docks there is a quieter place of semi-religious significance - the Shrine to Agasha Kasuga. While this could never happened in Rokugan because of how Yugozohime ordered him executed for his crimes, here Kasuga is revered and respected as the founder of the first settlement on Kameyama. The very island owes him his name. He named the mountain and several other features on the west side of the island. It was him who mobilised some Crab captains and orchestrated the first evacuation of the Merenaese from Rokugan, of which many did not return home but stayed on the island, forever changed by their experience of Rokugan.
But even his memory begins to fade, and it has consequences for the structure. It is mostly built on water, with the torii a distance away from the shrine complex, and the erosion rate of its wooden features is significant. Yubari is not obsessing about the worsening condition of the establishment as long as it serves its purpose. And funnily enough it has little to do with religion. Here on Kameyama the custom of inkyo never really picked up among sailors, but some of them certainly reach an age when it is time to step down because of health or burnout. If they have served the Tortoise well, they receive a small pension and are settled in these premises. They provide for themselves in part, but they also use the curiosity of young sailing wannabes who come to them to exchange stories, life hacks and maritime expertise for fishing, cleaning, cooking and fixing things. Dad jokes are extra.
Their official governor-appointed task is to maintain the hall of memory inside the shrine premises where various memorabilia are stored, both brought by others and the pensioners'. Between a rising collection of those and the tales of old sailors shared willingly it is a really good place to learn what it means to be a Tortoise. Recently, for some reason, some elderly from the other side of the island have joined the houses on beams and live together with the elderly.
For now, there is no priest, however, and the religious functions of the shrine are suspended, or maybe conveniently ignored. The pensioners like it more as a place where they can drink, sing lewd shanties and loiter around enjoying beautiful sunsets.
