日本銀行券 (Nipponginkōken) - Bank of Japan banknote 千円 (sen'en) - 1000 Yen 日本銀行 (Nipponginkō) - Bank of Japan 野口英世 Noguchi Hideyo - rather than a politician, the note features a bacteriologist 国立印刷局製造 (Kokuritsu insatsu-kyoku seizō) - Manufactured by the National Bureau of Printing - this is very tiny printing on front bottom center The watermark is gorgeous and extremely detailed. Tilting one section one way reveals a "千円." Tilting it another way reveals "1000." The side of the note contains a single translucent line. Other denominations show 2 or 3 lines. The bill also has raised ink so the visually impaired can differentiate between denominations. On the 1000 Yen the small black lines on bottom left and right have texture. The stylized seal in the middle also glows a certain way under UV light and the note contains numerous microscopic and hidden characters. As such, counterfeit Japanese notes make up a tiny fraction of currency in circulation. The note does not display a year. Others may know more about this, but the years apparently differ by the color of the serial numbers. I think this one is blue or 2019, but correct me if I'm wrong.
