TRANSLATION: raincoat fire
ALTERNATE NAMES: minomushibi, minoboshi, etc.; varies widely from place to place
HABITAT: wet rural areas
APPEARANCE: Minobi is a phenomenon that appears on rainy days in rural areas, particularly during the rainy season. Often it appears near bodies of water such as rivers or lakes, such as Lake Biwa in Shiga Prefecture. Minobi appears as a number of tiny fireballs which glow like fireflies. They float about in the air and tend gather in large numbers.
INTERACTIONS: Minobi gets its name from its tendency to gather around people wearing mino (traditional straw raincoats). It sticks to the raincoat and burns. When someone attempts to brush off or swat out the fire, the minobi instead multiplies, growing larger and larger. Eventually the person is forced to strip off the raincoat and leave it on the road.
ORIGIN: Minobi is found all over Japan, although often by different names and with different explanations. Sometimes this phenomenon is thought to be caused by natural gas escaping from the ground (as with other mysterious fireballs like onibi and kitsunebi). Most often it is said to be the work of a mischievous kitsune, itachi, or tanuki. Because it appears more frequently during the rainy season, sometimes minobi’s true form is believed to be a firefly or other insect, such as the minomushi (bagworm moth).
