TL;DR
Line-Yahoo Japan has made a non-binding counteroffer valuing Kakaku.com at $4 billion, directly challenging EQT’s bid. This signals a potential takeover contest for the influential Japanese review platform.
Line-Yahoo Japan, operated by Z Holdings Corporation, has launched a counterbid for Kakaku.com, valuing the company at approximately $4 billion, directly challenging the private equity firm EQT’s existing bid for the Japanese review platform.
According to sources familiar with the matter, the non-binding offer from Line-Yahoo Japan was announced on May 14, 2026. The move introduces a competitive dynamic in the ongoing acquisition process for Kakaku.com, which is known for its popular restaurant review and booking site Tabelog. EQT, the Swedish private equity firm, had previously expressed interest in acquiring Kakaku.com, and its bid has been considered a leading proposal. The counteroffer from Line-Yahoo Japan suggests a valuation of around $4 billion, which is higher than recent estimates of Kakaku.com’s market value. The exact terms of the counterbid have not been publicly disclosed, and it remains unclear whether this will lead to a formal bidding war.
Why It Matters
This development matters because Kakaku.com is a key player in Japan’s digital review and e-commerce sectors, with extensive user engagement and influence over consumer choices. A contest between Line-Yahoo Japan and EQT could reshape ownership and strategic direction for the platform, impacting competitors and stakeholders in Japan’s online ecosystem. The outcome may also influence future private equity and corporate takeover strategies in Japan’s tech sector.
