Oji Holdings Corporation announces that on August 23, it concluded a Basic Agreement on Protection of the Pitta with the Ecosystem Trust Society(Shimanto-cho, Takaoka-gun, Kochi Prefecture, Chairman: Mr. Takio Nakamura) in order to protect the habitat of the pitta, which has been designated as a threatened species.

The area covered by the agreement is the Koyagauchi Forest (area approximately 260 hectares) in Shimanto-cho, Takaoka-gun, Kochi Prefecture owned by Oji Holdings.Pitta habitat surveys conducted by the Ecosystem Trust Society since 2014 have shown that the company-owned forest is mating habitat for a number of pitta. Therefore, it was decided to conclude the Basic Agreement on Protection of the Pitta in order to preserve the environment so that the pitta can survive into the future.

The pitta is a beautiful migratory bird that is about 18-20cm long with multiple colors on its body.It arrives in Japan from spring through early summer and after breeding in the evergreen forests of Kyushu and Shikoku is said to head off towards Thailand and Borneo in the autumn to spend the winter. However, the details of its mode of life are not yet known. It is designated as “Threatened EN” (high risk of extinction in the wild in the near future) on the Japanese Red List of Japan’s Ministry of the Environment.
