Sakahoko

A spear set point-down.

Japanese dictionaries classify it as kokuji, a kanji made in Japan. Its form joins 金 (“metal”) and 逆 (“reverse”); the word is also written 逆鉾 or 逆矛.

Is 𫒼 the spear on Takachiho Peak?

It names the idea, but the object has its own history.

Local tradition links the summit spear on Takachiho Peak to Ninigi, a deity said to descend from heaven. Another version says it is the creation spear creator gods Izanagi and Izanami used to stir the sea into the first island.

Edo-period documents from Japan’s shogunate era mention the summit spear. That dates the written record, not the character’s coinage.
