Researchers of History on Modern Japan (HMJR, 日本近現代史研究会, also “KINGEN”) is a group of amateur “historians” founded in 2008 by Michio Ochiai (落合道夫), a member of Japan Conference. Kiyoshi Hosoya is the secretary general of HMJR, who hosts monthly lectures in Tokyo.
Under the leadership of Hosoya, HMJR submitted a position paper to the United Nations–see Alliance for Truth About Comfort Women Geneva Delegation (2016)–and filed an amicus curie in Gingery et al. v. City of Glendale.
