Newly appointed Bank of Japan Policy Board member Tadao Noda said Monday that entrusting stockholdings with trust banks is one way to boost the transparency of senior BOJ officials' financial assets.

"Entrusting stockholdings with trust banks is a strong option," said Noda, 59, a former deputy president of Mizuho Financial Group Inc., at his first news conference as a BOJ board member.

Noda stressed that his comments were his personal opinion.
