(Bloomberg) -- Japan’s rich have the largest accumulation of wealth in the Asia-Pacific region, at $7.7 trillion, but the legions of Chinese millionaires are rushing to catch up.

The pool of wealth held by China’s high-net-worth individuals grew by more than 144 percent between 2010 and 2017, to reach $6.5 trillion, according to the latest Asia-Pacific Wealth Report from consultants Capgemini. The equivalent rate of growth in Japan over the same period was about 87 percent.

More recently, India’s millionaires have been picking up the pace. Wealth held by Indian high-net-worth individuals rose close to 22 percent in 2017 compared with the previous year, the fastest growth in the region over that period, Capgemini said Wednesday.

And the rapid upward trajectory is expected to continue. After doubling between 2010 and 2017 to hit $21.6 trillion, the total pool of wealth held by HWNIs in Asia is expected to nearly double again to $42 trillion by 2025, Capgemini said.

Last year, wealth in Asia Pacific contributed 41.4 percent of all new HNWI wealth globally, the consultancy said. It defines HNWIs as those with investable assets of more than $1 million.

Despite challenges such as the trade war with the U.S., China’s wealth generation continued this year, according to William Sullivan, Capgemini’s global head of market intelligence. “It’s an exciting time for Asia,” he added.
