However, in 1774, a sense of urgency over the matter grew in both Higashi (East) Hongan-ji and Nishi (West) Hongan-ji Temples, and they cooperated in the submission of a proposal to the bakufu stating that only 'the Jodo Shinshu sect' (written as 浄土真宗) should be used as their formal name; this was seconded by Jodo Shinshu schools other than the Hongan-ji school, such as the Bukko-ji and Takada schools.
ところが、安永3年（1774年）、この事に危機感を持った東本願寺と西本願寺が一致して幕府に対して「浄土真宗」のみを公式名称とするように求める意見書を提出し、仏光寺派・高田派など非本願寺系真宗各派もこれに呼応した。
