Tankers navigating the Strait of Hormuz. This route, through which about 90% of Japan's oil imports pass, is now directly hitting Japanese construction sites due to its blockade. An era has come where insulation, paint, and unit baths—materials used in daily remodeling—no longer arrive due to tension in a distant strait.
The HORIZONS Inc. (CEO: Toshikatsu Oga, Hiratsuka City, Kanagawa) is currently offering 'Estimation Free Checker,' a free AI tool that judges whether a construction or remodeling quote is appropriate in 30 seconds. Against the backdrop of soaring building material prices following the February 2026 Hormuz Strait blockade, the company is working to protect homeowners with a tool to spot opportunistic price hikes and a PDF for negotiation.
### ■ Opportunistic Price Hikes Under the Guise of 'Material Shortages' Have Begun
Since the Hormuz Strait blockade in February 2026, Japanese construction sites have faced an unprecedented crisis. TOTO temporarily suspended new orders for unit baths (Nikkei, April 2026), sealing materials have seen price increases of over 30-40%, and shipment restrictions for insulation and roofing are following one after another (Shinken Housing, April 2026).
Under the pretext of 'soaring material costs,' the number of contractors adding unnecessary costs is surging. The 'structure of overcharging' that a 30-year construction professional has felt on-site is accelerating at this very moment.
Vessels navigating the Strait of Hormuz (2026). Due to a virtual blockade by Iran, the supply of petrochemical products for Japan has plummeted. Production halts and price hikes for construction materials like insulation, paint, and unit baths are occurring frequently.
### Hormuz Strait Blockade—The Lifeline Through Which 90% of Japan's Oil Imports Pass Is Now Cut Off
In February 2026, Iran virtually blockaded the Strait of Hormuz. With about 90% of Japan's crude oil imports passing through this strait, the supply of construction materials using petrochemicals as raw materials began to stop or be restricted nationwide.
TOTO has temporarily suspended new orders for unit baths. Sealing materials have increased in price by over 30-40%. Shipment restrictions for insulation and roofing are frequent. This is not just a problem of 'prices going up,' but an unprecedented supply crisis of 'materials not arriving at all.'
Taking advantage of this chaos, 'opportunistic price hikes citing material costs' are surging in the construction and remodeling industries. Homeowners have no means of judging whether a presented quote is a 'legitimate price hike' or 'overcharging.'
HORIZON SHIELD faces this problem head-on.
### ■ Surge in Access to AI Diagnosis Immediately After Release
After the service was released, API access to the free AI diagnosis has surged. Amidst a flurry of news about soaring building material prices due to the Hormuz blockade, homeowners worried about whether their quotes are okay are flocking to the tool. Figures show that anxiety over construction costs is reaching a critical point.
### ■ Why the 'Reverse Estimation Diagnosis PDF' was Born: Knowing the 'Fair Budget' Before Remodeling??
'Just write the work you want to do. KIRA will interview you and calculate 3 plans'—a reverse estimation diagnosis that lets you know the fair budget before consulting a contractor. You can grasp the budget with three plans (Pine, Bamboo, Plum) and approach negotiations with evidence. Free hearing is limited to once.
Get a 'Reverse Estimation Diagnosis PDF' to know the fair budget before requesting a quote from a contractor. Get a weapon for negotiation for 5,500 yen. 'I want to remodel, but I have no idea what the fair price is.'
Many homeowners sign contracts at groundless prices as told by contractors.
HORIZON SHIELD's 'Reverse Estimation Diagnosis PDF' fundamentally changes this structure. Before requesting a quote from a contractor, AI estimates the fair budget (free *some fees apply). Furthermore, for 5,500 yen, it discloses accurate amounts at the level of a small-to-medium contractor and delivers it the same day as a negotiation document with a market comparison graph, 5 negotiation phrases, and supporting source data. There will be a difference of hundreds of thousands of yen in the final payment between a homeowner who approaches negotiations with this document and one who knows nothing. In this current situation where material prices continue to soar due to the Hormuz blockade, it is a phase where homeowners must arm themselves.
### ■ Judging If a Quote Is 'High' in 30 Seconds—'Estimation Free Checker' Now Available
The AI tool 'Estimation Free Checker,' which judges in 30 seconds whether a construction or remodeling quote is fair compared to the market, is now available.
Simply enter the type of work, construction area, and quote amount, and it immediately compares them with a market database supervised by a 30-year construction professional.
