TOKYO, JAPAN, February 17, 2025 — CARTA COMMUNICATIONS Inc. (Headquarters: Minato-ku, Tokyo; Taku Meguro, Representative Director, President; “CCI”), a group company of CARTA HOLDINGS, Inc., conducted a survey of digital marketing professionals across the country in December 2024 and published a report on the Internet advertising market for the second half of 2024, with topics covering key industry trends and challenges, medium- to long-term strategies, and more.

About the survey
The survey has been conducted biannually since July 2020 to provide insights into how Japan’s Internet advertising market changes over time. The latest and 10th survey was implemented from December 11 through December 24, 2024 via email with a mix of advertisers, advertising agencies, publishers, media owners, platforms, ad tech vendors, and media reps. A total of 108 responses were received. The report was generated based on the survey results and data from CCI 360 Programmatic Display Market Analytics (see below).
Key findings
- Internet ad spend is on the rise.
40.7% of respondents reported an increase in online ad spend in the second half of 2024, which is up 6.2 percentage points from the previous survey. In the H1 2024 survey, those who reported an increase, decrease and no change were roughly equal in proportion, while the proportion of increase has risen in the H2, indicating a trend of increasing online ad spend.

- Programmatic display CPMs were generally higher in 2024 than in 2023.
The average CPMs for programmatic display ads showed a generally high trend, although fluctuating rather erratically, throughout 2004, ending up reaching the year’s high in December. The programmatic display CMP averaged at 136.6 yen in the second half of 2024.
The number of programmatic display impressions served also showed a generally high trend, but gradually declined after October.
This survey report also includes a list of average CPMs by product category with the year-over-year comparison between July-December 2023 and July-December 2024. The highest growth in programmatic display CPMs was seen in the housewares category. A total of 13 industry verticals experienced an increase in the second half of 2024 compared to the first half of year.

- Video ad spend remains robust in H2 2024.
When looking at media investment by type of advertising, video continued to show a strong trend in the second half of 2024.
More specifically, connected TV (CTV) scored the highest points among other ad types, although earning less points this time than in the previous survey. (Higher points mean more responses indicating an increase.)

- More than 70% of respondents say they’re not actively using retail media.
While many brands and advertisers are interested in retail media, a significant portion of them are still not actively using it, which also means that there is still room for further growth.
More than 70% of respondents reported that they were not fully leveraging retail media in the survey conducted in the second half of 2024.
The proportion of positive responses to the question asking whether or not they have ever used or suggested using retail media in their campaign executions or proposals decreased by 3.2 percentage points compared to the previous survey in H1 2024.

Based on these survey findings, the Internet advertising market sentiment is expected to see a gradual rise in the first half of 2025.

Other topics covered in this survey to gain insight on issues, challenges, medium to long term trends and efforts surrounding Internet advertising include:
