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.

From 2017, the largest denomination is the 50,000 soʻm banknote (early 2018 worth $6), which made the situation easier. The smallest denomination, the 1 tiyin, is only worth 1/2900 cent U.S. making it the "world's most worthless coin". However, coins and banknotes smaller than 25 soʻm are rare now.
