The annual Mainichi Daily News International Haiku Contest is now open for entries. Contestants are allowed a maximum of two attempts using a form on the competition website. Entry is free. But the standard is high.
To access the haiku page scroll to the Mainichi Daily News link in the A-Z list near the foot of this Poet-in-Residence blog and click. Once you are taken there simply follow the highlighted link to the competition form (not to be confused with the daily submission link). And good luck!
Strict classical form is not required for the international haiku competition and your submission may be in English or French. You can view winners from earlier years online.
Here's one I created for my own amusement earlier:
