Branding Works reveals AI recommendation trends for Japanese services

Branding Works has released the results of a fixed-point survey conducted throughout October 2026, analyzing how generative AI models like ChatGPT and Gemini recommend specific services in Japan. Using a proprietary LLMO measurement tool, the study tracked how frequently company names appeared in responses to specific queries.

In the marriage agency sector, IBJ Members was the most frequently mentioned service, appearing in 99.4% of responses with an average mention rank of 1.3. For recruitment agencies, Recruit Agent led the rankings with a 99.3% mention rate and an average rank of 1.3. Other notable mentions in recruitment included BizReach and Levtech Career.

The study highlights that AI models categorize recommendations based on specific user needs, such as the quality of support, the abundance of job listings, or high-class career opportunities. The research also noted that different AI models provide varying results; for instance, some companies saw significantly higher mention rates on Gemini compared to ChatGPT, and vice versa. Most AI responses cited comparison websites, such as Oricon, as their primary information sources.
