Being greatly different from other traditional Buddhist sects, which interpret the concept of missionary work broadly and have no direct relationship with political movements as organizations, it conducts in-depth activities socially and politically with other Shinshu sects, so that there is such a criticism from inside and outside the sect, as it is too active in movements of a political and/or leftist nature.
布教の概念を広く理解し、団体としては政治運動と直接の関わりを持たない伝統仏教各宗派とは大きく違い、他の真宗各派と共に社会的・政治的に踏み込んだ活動をすることから、政治運動的・左翼運動的過ぎであるという批判の声も内外からある。
