Momentor

Momentor Inc. is a Tokyo-based human resource and organizational development consulting firm founded in July 2022. The company applies industrial-organizational psychology research to help large enterprises and fast-growing startups prevent organizational rigidity and collapse. Its core methodology combines academic theory with practical business knowledge developed at DeNA (a major Japanese internet company), delivered through 3–6 month structured programs for executives, managers, and rising leaders. Momentor focuses on creating a common organizational language — diagnosing issues like psychological rigidity in leadership, generational gaps in talent development, and declining organizational efficacy.
