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.
