Natural serenity, unostentatious refinement, clean lines and the balancing of light and space are all hallmarks of Japanese interior design. In the new book from noted authors Marcia Iwatate and Geeta Mehta, "Japan Living" continues the themes of their highly successful "Japan Houses" with 30 specially designed houses that transcend function and resonate with spirit. The houses represented in "Japan Living" reflect the many changes in the dynamics of the new Japanese society, including an aging population and the desire to remain single; while others embody plenty of creativity, self-expression and individuality. Throughout, a return to traditional materials and design elements is married with such present-day requirements as minimalism, flexibility, a small kitchen, a beautiful bathroom, energy efficiency and electronic gadgetry. Each of these homes is an exquisite representation of the integrity consistently found within Japanese interior design, both in new construction and old.
