Musashi Shinjiro Residence is a residential project completed in 1980 in Kawasaki, Kanagawa Prefecture. Designed by Yuzuru Tominaga and Form System Laboratory, this 1979 work exemplifies thoughtful residential design from the early postmodern period. The residence demonstrates innovative approaches to domestic space organization and material expression characteristic of its era. Its architectural language reflects contemporary concerns with functionality and aesthetic refinement in private dwelling design. The collaboration between architect and research institute resulted in a distinctive approach to residential planning that merits study by those interested in late twentieth century Japanese residential architecture.
