Josenji Shin Ihai-do is a contemporary religious hall completed in 2022, located in Nakagawa Village, Nagano Prefecture. Designed by architect Yoshiaki Miyamoto, this facility serves as a new memorial tablet hall for the historic Josenji Temple. The structure represents a thoughtful balance between modern architectural design and traditional Buddhist spiritual purpose. Situated in the rural mountainous landscape of central Nagano, the building demonstrates contemporary approaches to sacred space design while respecting the temple's religious functions and local context.
