TL;DR
Major Japanese real estate firms warn of possible delays in condominium handovers due to supply chain issues stemming from the Iran war. No projects are currently behind schedule, but risks are increasing.
Major Japanese real estate companies have issued warnings to customers about potential delays in the completion and handover of new condominiums, citing ongoing supply chain disruptions caused by the Iran war. While no projects are currently delayed, industry leaders warn that risks are increasing due to persistent material shortages.
Several leading Japanese property developers, including Mitsui Fudosan and Sumitomo Realty & Development, have informed buyers that supply chain issues could impact the timing of condominium deliveries. These warnings follow disruptions in the supply of construction materials, particularly steel and other building components, which are linked to the closure of the Strait of Hormuz and broader geopolitical tensions involving Iran.
According to industry sources, while no projects have yet experienced delays, developers are preparing for the possibility as the situation persists. The supply chain turbulence has been exacerbated by recent sanctions and maritime restrictions affecting Iran, a key supplier of certain raw materials used in construction. Experts note that the situation remains fluid, with the potential for delays to materialize if the disruptions continue or worsen.
Why It Matters
This development is significant because it highlights how geopolitical conflicts, such as the Iran war, can impact real estate markets far beyond the immediate conflict zone. Construction delays could affect property prices, investor confidence, and housing availability in Japan, especially as the country seeks to address housing shortages and meet demand for new condominiums.

Background
The supply chain disruptions linked to Iran’s conflict have been ongoing since early 2026, with the Strait of Hormuz closure severely limiting the flow of raw materials like steel and other construction essentials. Japan, heavily reliant on imported materials, has seen increased costs and logistical challenges. Previously, developers had anticipated stable project timelines, but recent geopolitical developments have introduced new risks. Industry officials have emphasized that while no delays are confirmed, the situation remains unstable and could impact upcoming projects.
“We are monitoring the situation closely and informing our clients of potential delays, though no project has been affected yet.”
