Such culture is also useful in nature conservation, it contains insightful ecological knowledge passed down for generations. Japanese call traditional marine ecological knowledge ‘satoumi,’ and are putting great efforts into proper organization and handing down of the knowledge ( Tsujii and Sasagawa, 2012). This is an effort to not only utilize traditional knowledge and skills of fishing villages in marine management to overcome serious problems in coastal environment of Japan, but also is an attempt to introduce Japanese traditional knowledge to international arena as a new marine management technique. Right now, they are gathering and organizing traditional marine management techniques and culture in regional unit. Japanese government hosted independent seminars and meetings about ‘satoumi’ (Japanese word regarding coastal village) at the 10th Conference of the Parties (COP 10, 2010) to the Convention on Biological Diversity, which was held in Nagoya, Japan.
