Japanese youkai (mythical monsters) are known to all, with their quirky ways and unique characteristics. Some are fun, some spooky, and others just plain weird, they are the sources of popular legends and have greatly influenced manga (comic book) and animation sub-cultures. As it goes, the area around Oboke/Koboke is actually the original home to many of these monsters (there are hundreds if not thousands of these throughout Japan), particularly some of the most popular ones. Supposedly the monsters have traditionally been lured to the danger of the area (rapids, steep gorge, etc) making the area the home to the highest concentration of monsters in Japan.
