Goo-netkaitori Renewed with New Feature!

Proto Corporation Co., Ltd. (Headquarters: Nagoya City, Naka Ward, President: Toru Shiraki, hereinafter "our company") has renewed its car buying platform "Goo-netkaitori" and launched the "Pre-assessment" service on April 1, 2026.

Goo-netkaitori is a platform that utilizes the network of used car dealerships listed on "Goo-net," one of Japan's largest used car information sites, to create opportunities for users of "Goo-net" to sell their cars for purchase. In addition to the conventionally provided "Individual Assessment" function,

We have developed a service that allows users to sell their cars with peace of mind, including a "Pre-assessment" function where they can negotiate with a maximum of three selected auto sales companies, chosen based on our proprietary evaluation system developed through the operation of "Goo-net," and free provision of an escrow service to avoid the risk of non-payment.

Furthermore, as a promotion, we will launch a new commercial featuring actress Karen Otomo, focusing on TV, radio, web, and transit advertising.

Moving forward, our company aims to contribute to the development of the used car industry by realizing a richer "mobility life" for our users through data x technology built on the operation of "Goo-net."
