SADA has a link with the chief abbot of Todai-ji Temple and so on and when the statue of Birushana Buddha in Todai-ji Temple was drastically repaired during the Showa period, he held a rakkei hoyo (a memorial service to celebrate the construction of a temple) concert.
また、さだは東大寺の管長らとも縁があり、東大寺盧舎那仏像の昭和の大修理の際、落慶法要コンサートを行っている。
