Japan Post Bank, part of the post office was the world's largest savings bank with 198 trillion yen (US$1.7 trillion) of deposits as of 2006, much from conservative, risk-averse citizens. The state-owned Japan Post Bank business unit of Japan Post was formed in 2007, as part of a ten-year privatization programme, intended to achieve fully private ownership of the postal system by 2017.
