There is still time left to enter the International Kusamakura Haiku Competition. A contest description is available here.
As stated in the submission guidelines, the entry fee is free. Also note that if you submitted haiku between June 1st and June 10th, your poems could have been lost.
You may submit up to two haiku via their convenient online form.
Past winners in the English section (and poems) can be viewed here.
The web sites listed in this post have, at times, been unavailable. If you cannot access these sites, try again later.
Good luck! Perhaps you will win an all expense paid trip to the beautiful country that gave us haiku.
