TOKYO, Feb 23 (Reuters) - Japanese shares edged up in thin, choppy trade on Tuesday morning as continued volatility in oil prices dampened excitement over Wall Street's overnight surge.
The Nikkei share average edged up 0.3 percent to 16,156.49 in midmorning trade.
"There's been a tempering of bullishness in the Nikkei," said Stefan Worrall, director of Japan equity sales at Credit Suisse.
"The risks are finely balanced at the moment and without catalysts or a clear direction we're seeing a real lack of conviction in the market."

"There is a lot of noise at the moment and we continue to witness increased volatility across markets," said Martin King, co-managing director at Tyton Capital Advisors.
"How much this relates to Japan's Government Pension Investment Fund failing to have the ban on direct equity invesment lifted by the (Health, Labor and Welfare Ministry) is hard to quantify, but it would indicate that there will continue to be systemic injections of liquidity into the domestic ETF market, and the effect of this will not be lost on Japan's indexes and the instruments that track them."
