Major Japanese housing equipment manufacturers LIXIL and TOTO have stopped taking new orders for unit baths and toilets [1, 2].

This supply chain collapse threatens the domestic home renovation industry and highlights the vulnerability of Japanese manufacturing to geopolitical instability in the Middle East.

The disruption began when TOTO announced a halt on new unit bath orders on April 13 [2]. LIXIL followed on April 14, announcing that delivery dates for orders had become undetermined [3]. Both companies reported that inventories have been depleted, and they do not expect to determine new delivery timelines until July or later [1].

The crisis stems from conflict and instability in the Middle East, which has obstructed the supply of naphtha, a petroleum derivative [1, 2, 3]. Naphtha is a critical raw material used in the production of the plastics and components required for modern bathrooms and toilets. A TOTO spokesperson said that some raw materials are lacking because the supply of naphtha is stagnating due to Middle East turmoil [2].

Small-scale contractors are feeling the immediate financial impact. One residential renovation contractor in Fukuoka City said that sales are not being generated [4]. Because these manufacturers dominate the Japanese market, local contractors cannot easily switch to alternative suppliers during the shortage.

Despite the operational crisis, LIXIL has projected a consolidated net profit of 12 billion yen, a 47.4% increase over the previous year [1]. LIXIL President Kinya Seto said that because reasonable projections are currently difficult, these specific supply issues were not included in that planned value [1].

“TOTO and LIXIL have stopped taking new orders for unit baths and toilets.”

The situation underscores a critical dependency on petroleum-based raw materials for the Japanese construction sector. Because naphtha is a primary feedstock for the plastics used in prefabricated housing units, any disruption in Middle Eastern oil logistics creates an immediate bottleneck in the domestic renovation market. This suggests that the 'just-in-time' inventory model used by Japanese manufacturers may be insufficient to withstand prolonged geopolitical shocks.
