Yes, the main temple grounds, including the Goei-do Hall and Amida-do Hall, are freely accessible to visitors without joining a tour. However, certain special areas such as the Shiro-shoin, Kuro-shoin, Hiunkaku Pavilion, and other cultural treasures require participation in a guided tour. These tours are typically offered in Japanese and must be reserved in advance, with limited daily slots available. The tours usually last around 60 minutes and provide access to areas not otherwise open to the public. Individual travelers can still experience the temple's main architectural highlights and spiritual atmosphere without a tour.
