What were the onmyōji? Based on the latest research results, extensive records and materials, we will trace the profile of these ‘technical officers in charge of divination’. Picking up on the differences in each period, we will shed light on the actual life and work of the onmyōji, who from ancient times up to the beginning of modernity, were deeply involved in making and disseminating almanacs and calendars. This first ever full-scale exhibition of the Nara Koyomi-shi Yoshikawa-ke Shiryō collection of materials on the Nara Calendar Masters of the Yoshikawa Family will dig deep into the fascinating ways and world of the onmyōji and their almanacs and calendars.
