Almost all of Japan's major construction machinery manufacturers have their own used construction machinery divisions. Through professional assessment training for personnel with extensive experience in construction machinery services, they are turned into professional used construction machinery appraisers. These appraisers can then conduct professional assessments of used construction machinery according to unified standards and determine the prices of equipment to be recovered.

Take Komatsu of Japan, for example. Users can trade in their old equipment at relatively favorable prices, and at the same time, users who own used Komatsu construction machinery can dispose of it through trade-in, thereby giving Komatsu an advantageous position in the new equipment market. At the same time, Komatsu also has dedicated remanufacturing plants in Japan, where it uses the manufacturer's advanced technology to refurbish the used construction machinery it has purchased. By replacing parts and other methods, it substantially restores equipment functions, extends equipment life, and produces Komatsu-certified used construction machinery.

In Japan, each major equipment manufacturer has a complete used construction machinery recovery and auction system. Relying on auction companies under their own corporate umbrella or entrusting other professional auction companies, they hold regular dedicated used construction machinery auctions. Solid quality assurance, relatively favorable fees, and simple handover procedures are the reasons these auctions remain prosperous over the long term. The Japanese government has also made explicit regulations on the service life of new machines before they enter the used construction machinery market, which ensures that the used construction machinery market is reasonable and orderly and largely prevents unscrupulous traders from passing off inferior goods as high-quality ones.

A mature and complete used construction machinery circulation process ensures that Komatsu remains consistently ahead in the used equipment field. Although some domestic manufacturers are also gradually carrying out work in the field of used construction machinery circulation, they are still relatively at the initial stage, and in many respects there is still a large gap even compared with the relatively "mature" domestic used construction machinery market. The most important of these is the lack of a complete and high-quality assessment system.
