WAJA
WAJA, Worked All Japan prefectures Award, is something to hunt for if you are living in SM but it is not an easy one. You need to work all 47 prefectures
The three (3) prefectures I still miss are: 03 (Iwate), 05 Yamagata, 45 (Miyazaki)
If you know any station, or you yourself live in one of the missing prefectures, kindly let me know.
