LINE Yahoo is bidding to acquire Kakaku.com, operator of restaurant-reservation site Tabelog and price-comparison portal Kakaku.com, for approximately ¥690 billion, competing against a consortium led by European fund EQT.
The company views the acquisition as critical to an AI-era business model where revenue is generated at the moment of purchase, reservation, or job application—not just clicks—allowing it to combine Kakaku.com's transaction data with LINE's massive user base and AI agents to create new monetization streams.
What happened
LINE Yahoo announced on August 3 it will continue proposing to acquire Kakaku.com (which operates Tabelog and Kakaku.com price comparison), bidding against a competing group led by European fund EQT. LINE Yahoo and Bain Capital are offering ¥3,640 per share if KDDI cooperates, or ¥3,520 per share for a full public tender offer, totaling approximately ¥690 billion either way. EQT's tender offer runs through August 17.
Why it matters
LINE Yahoo sees Kakaku.com's reservation, purchase, and job-listing conversion points as essential to a new monetization model in the AI era. Rather than revenue from clicks alone, the company plans to charge at the moment users complete transactions—reservations on Tabelog, purchases on Kakaku.com, job applications on Recruit Box—combining customer reach, data, and AI. Tabelog integration with LINE's official accounts is described as a top priority.
What to watch
LINE Yahoo is also fortifying its AI agent "Agent i," which reached 12 million users in Q1 FY2026 with 25 domain-specific agents now deployed. The company is expanding LYP Premium (monthly ¥508) to 10 million subscribers by year-end—it grew to 6.82 million by Q1 FY2026—and launching a lower-cost "Light Plan Enjoy Pack" at ¥290 per month and a new LINE MUSIC tier at ¥1,080 per month.
LINE Yahoo's pursuit of Kakaku.com reflects a strategic bet on how AI monetization differs from traditional digital advertising. The company's CFO, Ryosuke Sakagami, explicitly framed the shift: in the AI era, revenue comes not from clicks but from "conversions"—the moment a user completes a purchase, makes a reservation, or applies for a job. Kakaku.com's three core properties (Tabelog for restaurant reservations, Kakaku.com for price comparisons and purchases, and Recruit Box for job postings) each represent a high-value conversion point. By acquiring these assets, LINE Yahoo gains not just user traffic but actionable transaction data—critical inputs for training and operating AI agents that can recommend products, restaurants, or jobs and capture a commission at the moment of completion.
This acquisition battle occurs against the backdrop of LINE Yahoo's accelerating investment in Agent i, which crossed 12 million users in Q1 FY2026 and now spans 25 domain-specific agents. The company is simultaneously expanding LYP Premium membership (aiming for 10 million subscribers by year-end, up from 6.82 million) and introducing lower-cost subscription tiers to broaden reach. These moves suggest LINE Yahoo is building a closed ecosystem—owned user base, owned transaction data, owned AI agents—designed to compete in an AI-driven commerce and services market rather than rely on advertising alone.
