The Japan Times reported on October 17 that the Japan International Cooperation Agency (JICA) will carry out a three-year study into the project, quoting an unnamed source close to the negotiations.
The study will examine costs, passenger demand, and funding options for the project, which is expected to cost around Rupiah 50 trillion ($US 4.4bn). The report says JICA will also look at the possibility of extending the route from Bandung to Surabaya in eastern Java.
