TOKYO -- Tokyo Metro on Wednesday embarked on a journey to transform from a public service provider into a potentially hot ticket for investors, with its shares soaring 45% on the day they debuted on the Prime section of Japan's main bourse.
The operator of the Japanese capital's 104-year-old subway system aims to take advantage of its position as a provider of vital infrastructure for the city of 14 million that is now a major hub of inbound tourism, a global financial center and a booming real estate market.
