The Finance Ministry said Tuesday it will put newly designed 10,000 yen, 5,000 yen and 1,000 yen bills into circulation on Nov. 1.
The new bank notes have holograms and other up-to-date technology to prevent forgery.
They were originally scheduled to go into circulation last month. The release was postponed due to work on designing a portrait of Meiji-era novelist Ichiyo Higuchi (1872-1896) for the 5,000 yen bill, which took longer than expected.
The redesigned 10,000 yen bills will feature educator Yukichi Fukuzawa (1835-1901), while the new 1,000 yen bills will feature microbiologist Hideyo Noguchi (1876-1928).
