A unique contest, KCJ contest, is held in every August.
This contest is getting to be one of the major CW contests among Japanese contesters.
An exchange consists of RST and two characters which stand for a prefecture name.
This makes a contact short and gives participants the likelihood of QSOs at high rate.

KCJ contest used to be a kind of domestic contest.
However, we recently have an increasing number of foreign participants enjoying this 
contest. 

All of the participants are required to submit their logs to the KCJ contest committee.
One of the most important features of this contest is that all of the submitted logs 
are cross checked for all QSOs to observe their data appearing in the log of the others.
If QSO data are not concordant with each other, these QSOs are disqualified and omitted 
for the calculation of the final scores.

Therefore, if you won't submit your logs after the participation in the contest or 
if you will submit irresponsible logs, you will make troubles to other participants.
Some Amateurs don't know that they may cause troubles on the band because of their 
selfish or imprudent behaviors.

Contesting is a kind of recreation but has its regulations to be strictly followed.
We think that amateur radio activities including a contest cannot be a good pleasure 
without an order.
However, a lot of unlawful operations are actually found in various settings both in 
ordinal and contest scenes.
We intend to clean these violations out from the band through the KCJ contest.
We also organize TOP band contest in every February for worldwide Amateurs.

An exchange two character code which stand for a prefecture name.
in total 62 Multi.
