On Jozikids you will find  a company that organises Kids Martial Arts Parties

A birthday party guide for kids interested in Karate, Kung Fu and Taekwondo. Kick, jump, tumble and celebrate your birthday!
When my son, who’s been studying Martial arts for several years, requested a Kung Fu birthday party, I had to put my party planning skills to the test. First, not all of his friends took classes, so there were safety considerations. Second, at the time there were no products on the market to give me a helping hand. Another consideration was our limited space and whether I really wanted eight children kicking, jumping and Karate-chopping their way through the house.

Problems solved…
We held the party at his Martial Arts School. They hosted parties every Saturday and it was very affordable. This covered the space and safety considerations. I provided black and red themed party products, party favors, beverages and the birthday cake. They supplied the space, activities, martial arts demonstration, introductory lesson and even cut the birthday cake with a broad sword! The kids’ faces lit up when the sword came out!

Call a local Karate, Kung Fu or Taekwondo schools and see if this an option. It’s great marketing for their business.
