10,000 yen note
The 10,000 yen note (1万円紙幣 "1Man-en shihei") is the largest banknote denomination of the Japanese yen. The front side of the 10,000 yen note includes a portrait of Yukichi Fukuzawa, a Meiji era philosopher and the founder of Keio University. The back of the note shows a drawing of the Hōō (, Fenghuang) in the Hall of the Phoenix, Byōdō-in.
1 yen coin
In 2011 the increasing usage of electronic money led to a lack of demand for the coin; as a result one-yen coins minted until 2013 were only released in mint sets. Production resumed in 2014 due to a consumption tax hike that went into effect. The cost of manufacturing 1-yen coins has become an issue in recent years. By the early 2000s the cost of manufacturing the one-yen coin had risen, and by 2003 it cost 13 yen to mint a sheet of coins. Measures were taken in 2009, including raising money from the private sector but that did not completely ease the cost of manufacture, which was 3 yen for each 1-yen coin in 2015. One yen coins remain popular in places like Osaka where the coins have been traditionally used for merchant transactions. In October, 2017 it was reported that as a result prices in general across Japan have been difficult to rise steadily.
