• Fracture filling type hydrate is also developed around Japanese Islands. The most well studied area is the E t i f J SEastern margin of Japan Sea.
• They are developed mainly in fracture of mud layer, seaThey are developed mainly in fracture of mud layer, sea floor and shallow subbottom, and are accompanied with the upward fluid flow from the deep to sea bottom.
• Scientific studies are not enough compared with the pore space filling type.
