The mission, closely aligned with the science priorities of the Japanese VLBI community, involves an active engagement of this community in the development of the mission, resulting in the formation of the Black Hole Explorer Japan Consortium. Here we present the current Japanese vision for the mission, ranging from scientific objectives to instrumentation. The Consortium anticipates a wide range of scientific investigations, from diverse black hole physics and astrophysics studied through the primary VLBI mode, to the molecular universe explored via a potential single-dish observation mode in the previously unexplored 50-70 GHz band that would make BHEX the highest-sensitivity explorer ever of molecular oxygen. A potential major contribution for the onboard instrument involves supplying essential elements for its high-sensitivity dual-band receiving system, which includes a broadband 300 GHz SIS mixer and a space-certified multi-stage 4.5K cryocooler akin to those used in the Hitomi and XRISM satellites by the Japan Aerospace Exploration Agency. Additionally, the Consortium explores enhancing and supporting BHEX operations through the use of millimeter/submillimeter facilities developed by the National Astronomical Observatory of Japan, coupled with a network of laser communication stations operated by the National Institute of Information and Communication Technology. © 2024 SPIEThe mission concept studies for BHEX within the BHEX Japan Consortium have been financially supported by the following programs and organizations. • MEXT/JSPS Grants-in-Aid for Scientific Research (KAKENHI) Grant Numbers: JP24684011 (T.H.), JP15H00784 (K.N.), JP15H03644 (Y.H.), JP19KK0081 (M.H), JP17K05398 (T.H.), JP18KK0090 (K.H.), JP18H03721 (K.N.), JP19H01943 (K.H., Y.H., K.N.), JP21H04488 (K.O.), JP21K03628 (S.S.-S., K.N.), JP21K13954 (Y.O.), JP22H00157 (K.H., S.K., K.N., M.K.), JP22H04955 (Y.U.), JP23K13155 (S.N.), JP23KJ0329 (S.N.), JP23H00117 (T.K.), JP23H00118 (K.N.), JP23K03448 (T.K.), JP23K03453 (S.K.) • MEXT as “Program for Promoting Researches on the Supercomputer Fugaku” (Structure and Evolution of the Universe Unraveled by Fusion of Simulation and AI; Grant Number JPMXP1020240219 (K.O., T.K.) / Black hole accretion disks and quasi-periodic oscillations revealed by general relativistic hydrodynamics simulations and general relativistic radiation transfer calculations; Grant Number JPMXP1020240054 (K.O., T.K.) • the Joint Institute for Computational Fundamental Science (JICFuS; K.O.) • the Multidisciplinary Cooperative Research Program in CCS, University of Tsukuba (K.O.) • the ULVAC-Hayashi Seed Fund from the MIT-Japan Program at MIT International Science and Technology Initiatives (MISTI) • grants from the National Science Foundation (NSF; AST-1935980, AST-2034306) In addition to the above programs, the BHEX mission concept studies have been supported by the Smithsonian Astrophysical Observatory, the Internal Research and Development (IRAD) program at NASA Goddard Space Flight Center, the University of Arizona, and the Black Hole Initiative at Harvard University.
