Japan's First: 'Urucamo' Gathering Pre-Listing Homes, Patents Its Unique System Combining AI Valuation and Buyer Reactions

*Japan's first: Refers to the patent acquisition for a property information intermediary system, server, and program that allows owners to obtain valuation amounts and buyer reactions before listing.

Tsukuruba Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Shuntaro Nomura) announced that its service 'Urucamo' (https://cowcamo.jp/urucamo) has obtained a patent for its unique system that simultaneously visualizes 'AI valuation amount' and 'buyer reactions'. (Patent No. 7857758)

This patent enables homeowners with potential needs of 'maybe someday I'll sell' to easily check the demand for their homes before starting full-scale sales activities. For buyers, as a place to encounter properties with sales potential, the number of registered members has exceeded 20,000, a 195% increase year-on-year (*), and the number of property posts has surpassed 4,000, showing rapid growth.

*Member registrations: Comparison of new member registrations between April 2024-March 2025 and April 2025-March 2026.

Unique System to Lower Psychological Barriers of Real Estate Sales

In traditional real estate sales, owners typically request an appraisal from a real estate company, sign a brokerage contract, and then list the property on portals. This poses high procedural barriers for those in the early stage of considering selling, who think 'I haven't decided to sell yet, but if there's demand, I might want to sell'.

Urucamo built a platform that allows users to 'check demand for their home without actually listing it'. In one case, an owner who posted before deciding to sell was encouraged by enthusiastic buyer reactions and closed a deal at a price 10 million yen higher than originally expected, creating a smooth and satisfying sales experience.

■ Summary of Patent: Visualization of 'AI Valuation × Buyer Reactions'

The patented unique system presents two indicators simultaneously to the owner (property owner):

1. AI-estimated valuation amount (+ photo valuation amount)

2. Real buyer reactions (actions like 'Like')

By combining these, owners can intuitively grasp not only the 'data-driven value (AI valuation)' but also 'actual market demand (buyer enthusiasm)', enabling confident sales decisions.

Buyer Benefits: Access to 'Properties with Sales Potential' Not Found Elsewhere

Typical real estate portals only list properties already for sale. However, Urucamo gathers potential 'maybe I'll sell' properties, so buyers can quickly discover 'properties with sales potential not listed on other real estate sites'.

Furthermore, buyers can send reactions like 'Like' or 'Want to view' to properties they like. Buyers themselves can directly approach owners (appealing demand) and trigger properties to be listed, offering a new experience unique to Urucamo.
