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.
500 euro note
Initially, the high denomination notes were introduced very rapidly so that in the first 7 years (up to December 2008) there were 530,064,413 five hundred euro banknotes in circulation. Subsequently, the rate of increase was radically slowed. In August 2018, there were approximately 515,000,000 banknotes in circulation (decreased from 614,000,000 in 2015). It is the second least widely circulated denomination, accounting for 2.4% of the total banknotes.
It is the largest note measuring 160 × 82 mm and has a purple colour scheme. The five hundred euro banknotes depict bridges and arches/doorways in modern architecture (around the late 20th century). The five hundred euro note contains several complex security features such as watermarks, invisible ink, holograms and microprinting that make counterfeiting very difficult.
