The “Kaizan-do” at Kodai-ji Temple is one of the most important buildings that form part of Kodai-ji Temple, built at the behest of the temple's founder, Kitanomandokoro (Nene), as a memorial to Toyotomi Hideyoshi. This hall was designed as a place to enshrine the statue of “Sanko Shoeki,” a master of the Rinzai sect of Zen Buddhism and master of the Kodai-in Temple, who was deeply involved in the founding of the Kodai-ji Temple. Sanko Shoeki was also the founder of Kodaiji Temple, and the hall's name “Kaizan-do” is derived from him. Architecturally, Kaizando reflects the beauty of traditional Japanese architecture, with its serene and prestigious appearance. Inside, a statue of Sanko Shoeki is enshrined, providing visitors with a space that evokes Zen teachings and historical background. Outside, a beautiful garden spreads out, offering seasonal views and contributing to the tranquil and harmonious atmosphere of the entire Kodaiji temple. Historically, Kaizan-do was built with the founding of Kodaiji Temple and has played a central role in the temple ever since. It has served as a symbolic place to tell the story of Toyotomi Hideyoshi and Kitanomandokoro and as a spiritual center for the spread of Zen teachings. Although the temple has undergone several repairs and renovations over the course of time, it has remained true to its original spirit and structure. Today, the Kaizan-do offers visitors to Kodaiji a rare opportunity to learn about history, culture, and the spirit of Zen. Its tranquil setting provides a place where visitors can find peace of mind and a special experience of traditional Japanese culture and spirituality.
