(Updates to midday)

TOKYO, June 23 (Reuters) - Japan's Nikkei average fell 1.2 percent on Monday, led down by blue-chip exporters like Toyota Motor Corp (7203.T) after sharp losses on Wall Street on rising oil prices.

Financial shares such as Mitsubishi UFJ Financial Group (8306.T) were under selling pressure after warnings of more mortgage-related write-downs at U.S. banks.

The benchmark Nikkei .N225 ended the morning down 162.27 points at 13,779.81. The broader Topix lost 1.2 percent to 1,341.14.
