The Tokyo stock market appears likely to remain on a roller coaster ride for some time, keeping the benchmark 225-issue Nikkei average seesawing between 13,500 and 14,500.

The Tokyo market bottomed out in mid-March, following the government's stock support measures and the Bank of Japan's quantitative easing of monetary conditions.

The subsequent round of stock price rises ended on May 7 when the Nikkei average hit 14,529.41, a level unseen since late December.
