East Japan Railway Co. will open retail spaces in Singapore metro stations as part of its overseas business expansion, aiming to cash in on purchasing power in Southeast Asia's richest economy.

Japan's largest passenger train line operator, known as JR East, said Tuesday it will open the shopping areas at 27 of the 32 stations on the Thomson-East Coast Line, which will commence partial operation by the end of this year.

The Tokyo-based company said it is the first Japanese railway operator to develop commercial facilities at stations in foreign countries.
