During the mid-Edo period, Uesugi Yozan, the head of the Uesugi family, nurtured the tiny spark of reform that remained within the domain, which was still suffering from poverty and confusion, and raised the idea of ​​reform throughout the domain, ensuring that not a single person died of starvation during the famine. He worked hard to overcome poverty and brought about the successful reform of the Yonezawa clan. When the first person continues to think about a wonderful future, that feeling is transmitted to many people who come after them, and that feeling is passed on step by step over 100 years until a single tree becomes a forest. That's what beliefs used to be. Takayama's planting of one million lacquer trees is a testament to his famous quote, ``If you do it, it will happen, if you don't do it, it will happen.'' This wonderful idea was strongly inherited by Takayama's subordinates, and even after the Meiji era, Yonezawa produced many of Japan's leading agricultural engineers. Over time, the lacquer used in Japan changed from being made in Japan to being made in China, but in recent years, a new national policy has been to use Japanese lacquer for the restoration of temples and shrines, and Japanese lacquer is gradually making a comeback.
