MicroAd Launches Inbound Promotion Support for Indonesian Tourists Using EternityX Travel Booking Data

MicroAd Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Kentaro Watanabe) has announced the launch of a new inbound promotion service for Japanese companies targeting Indonesian tourists visiting Japan. This service leverages Indonesian travel reservation data (GDS data) provided by its strategic partner, EternityX Marketing Technology Limited (Headquarters: Hong Kong; CEO: Charlene Ree).

Concurrent with the launch, the service has been adopted by PT. JCB International Indonesia, a local subsidiary of JCB Co., Ltd. (Headquarters: Minato-ku, Tokyo), to bolster its inbound marketing efforts.

By utilizing EternityX's data on airline and hotel reservations, the service enables high-precision targeted advertising through major social media platforms frequently used by Indonesians. Advertisers can now reach the 'pre-travel' segment (those with confirmed trips to Japan) as well as the 'during-travel' segment (identifying actual tourists while excluding residents) at optimal timing.

### Background and Market Growth In March 2026, inbound visitor numbers to Japan hit a record high of 3.61 million. Indonesia specifically saw a 36.6% year-on-year increase, reaching an all-time high for the month. Despite this growth, companies have faced challenges in efficiently reaching specific targets. Previous methods were often limited to broad 'Japan-interested' segments, but this new service allows for targeting based on confirmed travel plans.

### Key Service Features - **Precision Targeting via GDS Data:** Real-time data allows advertisers to target travelers based on their specific stay locations down to the prefectural level. - **Major Platform Support:** Compatible with Google, Meta (Facebook/Instagram), and TikTok—the most widely used platforms in Indonesia—to maximize ad effectiveness.

### JCB Case Study PT. JCB International Indonesia is implementing marketing aimed at promoting JCB card usage among its local cardholders during their visits to Japan. With the adoption of this service, JCB can effectively communicate promotional offers and convenience to travelers from before departure through their stay in Japan.

Akira Sato, President Director of PT. JCB International Indonesia, commented: 'By leveraging GDS data, we can achieve a consistent and highly accurate approach from pre-departure to arrival. We expect this to significantly enhance our marketing effectiveness.'

MicroAd plans to further strengthen its partnership with EternityX and expand its network across Asia to continue solving inbound marketing challenges for enterprises.
