PoC Commences for Circular Economy Platform 'Yukyu Market' at Yaechika Tokyo Station Cleaning and Security Sites
PAX TOPOLOGY Inc., in collaboration with Yaesu Service Inc. and Tokyo Plaza Service Inc., has launched a proof-of-concept (PoC) for its circular economy platform 'Yukyu Market' at Tokyo Station's Yaechika. Running from May 11 to June 30, 2026, the initiative visualizes decentralized idle assets—such as cleaning and security equipment—to verify cost reductions in procurement and disposal.

PAX TOPOLOGY Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director and CEO: Ken Okumura; hereinafter "the Company") has commenced a proof-of-concept experiment (hereinafter "this PoC") in collaboration with two companies: Yaesu Service Inc., which handles security operations at Yaechika (Yaesu Underground Shopping Mall), and Tokyo Plaza Service Inc., which manages cleaning operations. This initiative aims to verify the effectiveness of 'Yukyu Market' (Idle Market), a circular economy management platform that visualizes internal idle assets and promotes their reuse.
In this PoC, the Company's platform will digitally visualize cleaning equipment, security supplies, and office items scattered across multiple bases in the vast underground mall. By eliminating the hassle of "searching, transporting, and coordinating," the experiment will evaluate the impact on reducing procurement and disposal costs in multi-base facility management.

■ Background and Challenges: "Hidden Assets" in Facility Management
In the maintenance and management of expansive commercial facilities and underground malls, a wide variety of equipment is used daily, including cleaning tools, security supplies, and backstage fixtures. However, because operational bases are decentralized, it is often unclear "who" holds "what" and "how much." This lack of visibility makes it difficult to make optimal management decisions regarding the procurement and disposal of inventory, fixtures, and materials.
■ What is the Circular Economy Platform 'Yukyu Market'?
'Yukyu Market' is a platform that digitally visualizes a modern organization's idle assets and encourages circular reuse. It allows users to intuitively search for and discover internal idle assets much like an e-commerce site, offering on-site staff a new procurement experience where "sourcing from within the company is faster and easier than buying new."

[Three Features of Yukyu Market]
Frictionless Marketplace: Supports the digital cataloging of various corporate assets with AI listing support features, including image recognition technology.
AI Economic Rationality Judgment: Learns the "break-even point" for each item and automates the decision of whether it should be "transported or disposed of." It actively blocks transactions where reuse would undermine economic rationality.
GHG Emission Reduction Calculation: Automatically calculates the Scope 3 (Category 1, Category 5) equivalent of CO2 emissions avoided through the use of Yukyu Market as a concrete GHG emission reduction figure.
■ Overview of the Proof-of-Concept
This PoC implements 'Yukyu Market' at various security and cleaning standby areas and field warehouses within the underground mall.
Duration: May 11, 2026 – June 30, 2026 (Approximately 2 months)
Location: Cleaning and security bases, and related backstage areas in the underground mall
Target Items: Cleaning equipment (polishers, high-pressure washers, vacuum cleaners, etc.), security and safety supplies (traffic cones, uniforms, informational signs, etc.), and office supplies (folding chairs, lockers, etc.)
Validation Details:
Operations for digitally cataloging inventory, fixtures, and materials within business sites.
Efficiency of the listing and procurement process for idle assets across multiple bases (impact of reducing search and coordination costs).
Calculation of the financial reduction in new procurement and disposal costs.
■ Future Outlook
Based on the data and operational know-how gained from this PoC, the Company will accelerate the horizontal rollout of the service to related parties and expand its offering to other large-scale commercial facilities and building management companies. "Yukyu Market" aims to transform the backstage from a mere cost center into a "value-generating distributed warehouse," building a sustainable infrastructure where every company's fixed assets are mobilized as liquid assets.

FAQ
Where is the PoC taking place?
It is taking place at the cleaning and security bases, as well as the related backstage areas, of 'Yaechika', a large underground shopping mall connected to Tokyo Station.
Which companies are participating?
PAX TOPOLOGY Inc., the system provider, along with Yaesu Service Inc. and Tokyo Plaza Service Inc., which manage operations at Yaechika.
Why is AI judgment necessary for reuse?
Because the cost of transporting an item to another location can sometimes exceed the cost of buying a new one. AI calculates the break-even point to prevent economically irrational reuse.
