Hibagon is the Japanese equivalent of the Yeti from the Himalayas, or Bigfoot from North America. It is usually sighted on Mt. Hiba (Hiroshima prefecture), hence the name.
I have never seen Hibagon myself, even though I have visited Hiroshima several times.
Hibagon font is a nice, handpainted, all caps font with a mythical feel to it. It probably won’t scare you, but it will look good on anything that needs a bit of brushwork, or a bit of roughness.
