There is a nameless shrine on a mountaintop somewhere in the Nanpo islands of japan. Maps do not list it, and the torii crowning the entrance has been buried. A single red lacquer horn is all that exists to show the way to this shrine, which lies up a difficult incline of 108 steps.
The body of the shrine itself was constructed of driftwood and fitted together without nails. The only adornment of the shrine is a hemp rope bearing two ragged rice paper shide.
In this shrine is a mulberry tree. No matter how many years pass, this tree remains exactly eight inches in diameter. Instead of fruit, the tree bears silk strands.
There is a village at the foot of this mountain. They have no record of any shrine, only that the village once produced fabrics of the finest caliber during the Tokugawa shogunate. Villagers will blithely say the silk was imported, that no mulberry has ever grown on island soil. Invite them to the mountain, they will decline. There is nothing up there, why bother?
The mulberry silk strands are unusually tough and course, many magnitudes thicker than that produced by Bombyx mori. Coring the trunk is inexact, for the wood had a plasticity not common in the mulberry family. The only factor restraining regular harvest is that the silk, once plucked, takes many weeks to grow back.
In the village of this island, there were five founding families. Five homes producing silk. This is evident in the tax records of the Edo merchant who imported the fabric. Then, suddenly, there were four families. Why? Where did they go? Modern villagers will shrug their shoulders. Lots of things happen in a few years. Battles are found or lost. Ships crash. Why bother digging up the past?
Examination of the tree roots will turn up another anomaly. At the end of each root is a peculiar oblong scale. Tests of these scales show that they are not wood but a protein structure unique to the tree. Attempted removal only results in an excess of sap flowing from the point of injury.
Tax records from mainland Honshu tell of a time of unrest on the island. A dip in both quality and quantity. A peculiar red, unique to the island, vanished from the shipment forever. A note of usury from the silk supplier, demanding to know the whereabouts of a third of the raw materials. And then…nothing. The next year shows a slight uptick in production, minus the red fabric. The village no longer produces silk, getting by on subsistence farming and fishing in the modern day.
There is a matsuri unique to the island, taking place at the end of spring. Thirteen square holes are dug, and straw dummies that have been beaten with farm implements are places in the holes and set alight “to salt the ground.” Minor excavation of the festival grounds have turned up roof tiles, indicating there was once a house on the land.
Every spring, as matsuri lanterns light up the village at night, the tree weeps sap.
