The AJD (All Japan District) award from JARL (Japan Association of Radio Amateurs) is, in my opinion, the easiest to obtain and most likely to be awarded.
It certainly wasn't because all FT8 users were Japanese.
The requirements for AJD's application are: to establish communication with ten radio stations in different regions of Japan (receiving transmissions from all ten regional radio stations).
Obtain QSL or SWL cards from any of the ten listed radio stations (e-QSL is acceptable).
Application Process:
Open https://www.jarl.org/English/4_Library/A-4-2_Awards/sample-form.doc Download the form and fill it out (you can refer to my application form).
(The address field in the table is your delivery address)
Open https://www.jarl.org/English/4_Library/A-4-2_Awards/Award_Main.htm Select "Awards - Foreign" and click "Add to Cart". This will automatically open PayPal, where you can then make the payment (if you don't have a PayPal account, you can use a credit card or other payment method by clicking the button below).
Keep screenshots of payment records, and send the completed forms and screenshots (without QSL cards) to: intl@jarl.org It usually takes about 5 days to find out if the application was successful. The QSL card will then be mailed to the address on your application form (standard letter) within approximately three weeks. The envelope is A4 size and includes a rigid piece of cardboard to prevent creases in the certificate.
