TOKYO (Reuters) - Nomura Holdings ( NMR ), Japan's biggest brokerage and investment bank, reported on Friday a 670% jump in quarterly net profit compared to a year earlier as its retail income rose to its highest in eight years.

January-March net profit was 56.8 billion yen ($363.87 million) compared to 7.3 billion yen a year earlier when worries about a global banking crisis engulfed global markets and hit Nomura's investment banking business.
