Japanese firms are involved in a clash of titans that is expected to intensify this year between two successful ride-hailing startups in Southeast Asia.

Fierce competition is looming between Indonesia's Gojek and Singapore-based Grab, which is backed by companies including SoftBank Group Corp., Toyota Motor Corp. and Yamaha Motor Co.

Gojek is backed by Singapore's largest local bank (DBS Bank), technology giant Google, Chinese internet services giant Tencent, Singapore sovereign wealth fund Temasek and Chinese online food giant Meituan-Dianping.
