Supply and demand were balanced across all 13 surveyed items
Japan's Ministry of Land, Infrastructure, Transport and Tourism reported on August 25 that supply and demand were balanced for all 13 items across seven major construction-material categories surveyed between August 1 and 5, including ready-mixed concrete, steel and timber. Inventory conditions for aggregates, reinforcing bars, H-beams and timber were all classified as normal. The national survey therefore does not indicate a widespread shortage of major materials, although it does not eliminate differences by region, manufacturer, specification, quantity or delivery schedule.
H-beam prices were slightly higher while other materials were flat
H-beam prices were classified as slightly rising from the previous month, while the other surveyed material prices were flat. Total construction cost, however, is not determined by materials alone. Labor, transport, project management, equipment and site conditions all affect contractor quotes. Balanced material supply therefore does not automatically mean that renovation or new-construction prices will fall. The separate July labor survey continued to show shortages among skilled workers, demonstrating why materials and workforce availability need to be analyzed separately.
Overseas owners should check quote validity and material specifications
When an overseas owner renovates a Japanese resale home or commercial building, focusing only on the total contractor quote can create unexpected costs if specifications or materials later change. Before signing, owners should understand the manufacturer or grade included in the quote, lead times, quote-validity period and treatment of substitutes. A material classified as balanced nationally does not mean that imported equipment or specialized products are equally available. Combining material procurement and contractor staffing in a realistic project schedule improves estimates of the time until completion and income generation.
