Toto Suspends Bathroom Orders As Shares Drop 7.2% On Supply Crunch

Supply chain stress tied to the Iran war is now surfacing in Japan’s industrial base, with Toto Ltd. (TOTDY) taking a visible hit as material shortages begin to disrupt production. The company has suspended new orders for its prefabricated and modular bathrooms, informing business partners of the halt on Monday, while indicating it does not yet know when orders will resume. The market reaction was swift, with Toto’s shares falling 7.2% in Tokyo, marking their steepest one-day decline in a year.

The disruption appears tied to broader instability across oil-linked supply chains, particularly for Japan, which remains heavily dependent on the Middle East for energy inputs. Toto noted that procurement conditions for raw materials, both domestically and internationally, have become extremely unstable as a result of the conflict. Japan sources more than 90% of its crude oil and nearly 45% of its naphtha from the region, and that dependence could be feeding directly into shortages of key inputs such as organic solvents used in coatings for modular bathroom walls and ceilings, a core component of its housing-related products.

The strain is extending beyond a single company. Takara Standard Co. said Middle East tensions are destabilizing supplies tied to naphtha-based materials, with its shares dropping 6.6%, the largest decline since August 2024. Lixil Co. (JSGRY) has also flagged unavoidable supply restrictions and rising costs for materials including resins and aluminum. While Japanese officials have indicated naphtha inventories could cover at least four months of demand, industry efforts to secure alternative supply sources suggest the pressure on manufacturers could persist in the near term.
