Tokyo Gov. Yuriko Koike on Friday announced her plan to revitalize the nation's capital and reaffirm it as a top financial center, a move aimed at boosting the country's economic growth in line with Prime Minister Shinzo Abe's ¥600 trillion GDP target for 2020, the year of the Olympic Games.

At a regular news conference at the metropolitan government office in Tokyo's Shinjuku Ward, the governor said Tokyo is key to shoring up the nation's economy, and that she hopes for a return to its former position as Asia's leading financial hub.

The governor said she would do so by easing regulations and revising the tax codes, which she says are deterring potential international investors from entering the Japanese market amid fierce competition from overseas competitors such as in Singapore or Hong Kong.
