Japan In-App Advertising Industry Trends and Drivers:

The Japan in-app advertising market size is anticipated to witness substantial growth in the forecast period on account of the large-scale proliferation of smartphones, high demand for mobile apps, and advertisers diverting budgets from traditional media towards digital media. Japanese consumers spend a lot of time on mobile apps in entertainment, games, social media, shopping, and utilities, which significantly benefits advertisers to capture highly engaged consumer groups. The increasingly sophisticated nature of mobile advertising technologies – such as programmatic, real-time bidding, advanced targeting, and live performance tracking – has also meant that in-app advertising has become one of the most effective, and measurable, solutions for marketers looking for a positive ROI. The COVID-19 pandemic accelerated digitization and mobile app usage with consumers increasingly using mobile phones for entertainment, communication, shopping, and information consumption, thus driving the upsurge momentum of in-app advertising.

The Japanese in-app advertising market is also characterized by the presence of sophisticated data analysis and user segmentation features that can provide advertisers with abilities to serve customized and relevant ads according to the user’s demographic information, behavioral patterns, interests, and geographical information. Video ads are growing especially fast thanks to their captivating nature, high completion rate and ability to effectively communicate brand messages, complemented by faster mobile network speed and unlimited data subscription plans. Gaming apps also provide the largest platform for advertisement, with developers profiting from ads in free-to-play games while navigating how to balance the user experience with revenue generation. Interstitial and rich media ads running over interactive immersive experiences are increasing in popularity as advertisers are looking to increasing engagement level. Though the Android platform dominates the market largely due to its availability, iOS users tend to be more prestigious and have better user engagement, hence attracting more premium advertisers. In addition, the use of artificial intelligence for ad optimization, burgeoning trend of e-commerce and mobile shopping, rising investment on mobile marketing by brands across industry verticals, and availability of privacy-preserving advertising technologies are set to drive the market growth during the forecast period.
