Excite Japan, one of Japan’s leading internet portals, announced today that it has teamed up with Jakarta-based conglomerate Sinar Mas, to start working an online ad service in Indonesia. The companies previously established up a joint venture called Excite Indonesia earlier this month. The new company will launch an online ad service that gives rewards to mobile users of SmartFren Telecom, one of Indonesia’s largest mobile operators. They hope to acquire 100 advertisers by the end of this year, and expect the annual turnover to reach 600 million yen (about $6.12 million) in 2017. This is the first time for Excite Japan to launch a local office outside Japan. The company is expecting to explore more business opportunities in Southeast Asian region in the future. Excite Japan is a subsidiary of Japan’s largest trading company Itochu Corporation. In Taiwan, it has invested in two companies: e-commerce platform PCHome, and the review site Fashion Guide. Should this point rewards system prove successful in Indonesia, the company plans to bring it to the Philippines next.
