Tengubi is a fireball phenomenon seen near rivers in Aichi, Shizuoka, Yamanashi, and Kanagawa Prefectures. It appears as one or more (up to several hundred) reddish flames which float about in the sky. These supernatural fires are said to be created by tengu. Tengubi descends at night from the mountains to the rivers. Often it starts as a small number of fireballs which split into hundreds of smaller flames. These flames hover above the water for some time, as if dancing. Afterwards, they return to the mountains. In most cases, humans who witness tengubi invariably meet with disaster—usually in the form of a serious illness contracted shortly after the encounter. Because of this, locals who lives in areas where tengubi is common greatly fear this phenomenon. If a local happens to see a tengubi, they will immediately drop prone and hide. Oftentimes they will cover their heads with their shoes or sandals. Occasionally, tengubi can he helpful to humans. During times of drought, it was common for rice farmers to secretly steal water from their neighbors by redirecting water from the canals into their own fields during the night. This caused a great deal of conflict among the people involved. However, when tengubi appeared above the canals, would-be thieves were thwarted—either out of guilty consciences or because the light from the tengubi made it impossible to sneak around. Tengubi is created by kawa tengu—”river tengu” who prefer the riversides over the deep mountain valleys where tengu normally live. It is used by these tengu to catch fish at night. For this reason it is also known as tengu no gyorō (“tengu fishing”). Toriyama Sekien included this phenomenon in his book Hyakki tsurezure bukuro under the name taimatsu maru (taimatsu meaning “torch,” and maru being a popular suffix for boys’ names). He described it not as a tool for tengu to help with fishing, but as a way for them to hinder and interfere with the religious practices of ascetic monks.
