    In February 2022, a petition with more than 42,000 signatures was submitted to Niigata Prefecture by the Association for Making Jade the Stone of Niigata Prefecture, requesting that jade be designated as the stone of Niigata Prefecture.As a result of deliberation by the review committee established in response to this, jade was designated as the stone of Niigata Prefecture on November 4, 2022.
    Jade is a gem that has been distributed throughout the country since ancient times as a decorative item such as magatama.Japan's jade culture, which has been cultivated mainly in Itoigawa, boasts the world's oldest history.The story of the birth of jade dates back to about 500 million years ago, long before the formation of the Japanese archipelago, and it is a symbol that connects the land of Japan, which is located in a mobile zone, and the eternal culture that has taken root there.
