  KCJ Contest held in every August is one of the major CW contests in Japan.

  Our Contest Exchange is unique – RST report plus two alphabets, such as TK for Tokyo,
 meaning a Japanese Prefecture/District.
 This makes a contact short and eventually, makes it possible for a participant to work at a higher rate.

 Thankfully, we are welcoming more and more participants from abroad. Based on this fact,
 in order to make KCJ Contest popular all over the world and much more enjoyable for them,
 we made several revisions of the contest rules for KCJ Contest in and after 2021,
 and for KCJ Top Band Contest since 2022. According to our new rule, a foreign participant gains one point
 by a contact with another (Previously, no points).
 And the Contest Exchange for a foreign participant is changed from Continent Code to CQ Zone Number
    (for example: not NA but 03).
 As you well understand that KCJ Contest Committee completely engage in cross-checking both logs:
 from you and the station you worked. Therefore, YOUR LOG SUBMISSION IS INDISPENSABLE. We really appreciate
 your kind cooperation.

 We do hope foreign participants have more fun with those revisions and enjoy KCJ Contest further. Good Luck!
