The impact is spreading nationwide. Major developer Mitsui Fudosan has reportedly notified buyers that housing handovers could be delayed due to unstable supplies of construction materials using naphtha-based products. Last month, Toto temporarily halted orders for unit baths because of shortages of adhesives and other materials, while major housing equipment manufacturer Lixil announced plans to sequentially raise prices on toilets, kitchens and other products from August onward. Japan imports roughly 60% of its naphtha from overseas, with more than half sourced from the Middle East, leaving the country heavily dependent on the region.
