Japanese government bonds worth 75 billion yen that went on sale at post offices Wednesday were snapped up in just four hours, according to the Postal Services Agency. The JGBs were also offered at major banks, but most buyers chose post offices because no commissions are charged there, they said.

The first portion of JGBs, worth 50 billion yen, went on sale at post offices Feb. 3 and sold out by around noon, they said.
