TOKYO, April 8 (Reuters) – The Nikkei share average hit a 15-year high on Wednesday, supported by solid buying from domestic investors after Japanese retail investors ploughed a sizable amount of cash into new stock mutual funds.

The Nikkei rose 0.8 percent to 19,803.02, its highest level since April 2000.
