Information on price increases for housing-related materials was published on 24 September, with numerous companies, including Aica Kogyo Co., Ltd., implementing increases on shipments.
This list compiles price increase information for housing-related materials as of 24 September, with increases often applying to shipments or orders received by each company. The table sets out price increase rates by product and their effective dates, as price revisions across a wide range of products are being implemented against a backdrop of supply constraints and raw material price trends. This could also affect procurement terms for building materials and equipment.
Among the key developments, Aica Kogyo Co., Ltd. announced a 10–30% price increase for melamine decorative laminates and decorative boards on shipments from 1 June 2026, while Asahi Kasei Construction Materials Corporation announced a 20% increase, mainly for Neoma Foam, on shipments from 7 May 2026. Asahi Woodtec Co., Ltd. will apply a 10–15% increase to flooring products and a 15% increase to other products, covering all products it handles, from orders received on 1 June.
Many other companies have announced similar measures, and the list includes price increases across a broad range of building materials, including asphalt waterproofing materials, insulation, wall and flooring materials, and doors and fittings. Further additions or revisions to individual price increase rates and effective dates may be made as raw material costs fluctuate and logistics costs have an impact.
