The 2000 Yen Banknote, Popular in Okinawa, Unknown in Mainland Japan

From Nippon.com:

The ¥2,000 banknotes never gained popularity, despite the promotional efforts of the Ministry of Finance and the Bank of Japan, because most ATMs and vending machines did not issue or accept them. Circulation peaked at around 510 million notes in August 2004, and then declined rapidly thereafter. Since that fiscal year, no new notes have been printed, and the number in circulation has remained just below 100 million, which is only 0.6% of all banknotes in circulation. The notes have become so rare that many people have never encountered one or wonder if they can still be used to make purchases.

However, in Okinawa the situation is quite different. The note has special significance for residents of the prefecture because it features an illustration of the Shureimon gate of Shuri Castle, which is the symbol of Okinawa. ATMs for Okinawa Bank and the Bank of the Ryūkyūs have a “¥2,000 priority button” that allows users to choose to withdraw these notes to use for their daily purchases.

I distinctly remember using an ATM in Okinawa for the first time and the 2000円 notes being spit out. Was my first time seeing them and I briefly thought I was being scammed. They are beautiful banknotes and the only remaining ones with the previous design language since they were not changed with its 1000円, 5000円, and 10000円 comrades.
