In the lawsuit, Hanryumura had claimed the scores for about 20 outlets of its Korean barbecue chain KollaBo fell about 0.2 point on average on the rating scale of 1.0 to 5.0 points when the site's algorithm was changed in May 2019, with the largest fall reaching 0.45 point. Seeking about 639.05 million yen in damages, the chain argued that the number of restaurant customers fell by more than 5,000 per month after the change. Kakaku.com said the change in the algorithm was made in the interest of its users, and score fluctuations should be naturally assumed.
