Volunteers from the executive committee of “The Final War at Sekigahara, Ogaki Exhibition” held in Ogaki City in 2000 set up the “O-kaki Project Executive Committee” and are promoting the Kaki Tree Project to elementary schools and junior high schools in Ogaki City. The trees were planted in the park of Ogaki Castle, Kono Elementary School and Higashi Junior High School in 2000 and 4 more trees were planted in 2001 in a place such as Akasaka Elementary School, Yasui Elementary School, Uruu Elementary School, Higashi Elementary School.
