    Secrets to a smooth children’s Sumo party

    Secrets to a smooth children’s Sumo party

    From Ash Jumping Castles and Sumo Suits Sydney

    Make sure you have a Gyoji

    This is the official Sumo referee; he or she should be skilled at crowd control – no matter how big or small your contestants!

    Minimise distractions

    The best parties are when everyone is focused on the ‘fighting’; it creates a human amphitheatre. Children can be distracted by the smallest things when they are waiting for their turn so you will do well to keep things like balls and balloons out of sight. Fortunately, having the party table laid out and ready doesn’t ever seem to act a distraction…more of an incentive!

    Chairs aren’t needed

    It is an important for safe Sumo that the area around the mat is clear of chairs. The children will be seated on the floor at the side of the mat supporting their team.

    Don’t encourage the birthday girl or boy to pick teams.

    Your `Gyoji` should sort out the teams by height so that everyone has the best chance of a good fight.

    Sitting down

    Your Gyoji is only one person in the midst of a dozen exited children. He or she should make a big deal about getting the children to sit down at the side of the mat whilst a fight is in progress. When the children keep this discipline he can spend more time on running the fights than on herding kids, resulting in more goes all round.


    Sumo Suit Short Q&A

    Sumo Suit Short Q&A

    How long does it take to get a suit on?

    1. Putting on a sumo fat-suit is just like pulling on a big heavy vest, then all that is needed is the neck brace and helmet (both Velcro fastened). When you get used to it, it should take as little as 15 seconds to get a suit off one combatant and another 15 to get it onto the next. So to swap out one pair for the next is about a minute; leaving more time for posing and fighting!

    How much space do you need for a Sumo Experience event?

    1. Ash Jumping Castles recommends about 5×5 metres, which is the size of our crash mat. You can also think about hiring our inflatable arena, which is perfect for kids and requires a space of 7m x 7m. Its always advisable to hold the games outside do kids (or adults!) aren’t crashing into walls. Don’t have space in your backyard for a Sumo party or bouncy castle? Think about letting your local council know and having your party in the park.

    Which suits are right for me?

    1. See the ‘Sumo Suits’ page for further details; we have both adult and junior suits that cover all ages from approximately 7 upwards, but dependant primarily on the height of the combatants. We have observed that, well, those who have started to develop the attributes of a real Rikishi (Sumo wrestler) may find the suits a little tight!

    How long should a Sumo session run?

    This depends on the number of people you are hosting but towards the end of 90 minutes the attention of the children will start to wonder and the rules will be relaxed in response. Younger children will start to run around at this stage, which is quite natural. Even for 7 and 8 year olds you would normally expect to keep them all engaged for at least the first 75 minutes.


    Trends in Corporate Events

    Food carts, Pop-ups, virtual reality, holograms have all been discussed as trends in event entertainment.

    However if you are really looking at engaging your team, clients or co-workers, bouncy castles provide a fun, energetic throwback to childhood.

    Recent surveys also suggest attendees at corporate events expect more healthy options and exercise *. There is no better, more fun way to spend a bit of energy than an adult jumping castle!

    Our Jumping Castles and Commander Obstacle Courses are perfect for the smallest or largest corporate parties and events in Sydney. Our prices are reasonable and your guests will be talking about it for months to come!

    Jumping Castle History

    Jumping Castle History

    The first corporate event with a bouncing castle happened by accident.

    John Scurlock, a mechanical engineer from Shreveport, Louisiana, was experimenting with inflatable tennis court covers in 1959 when he noticed his employees jumping playfully on the covers.

    He started out with a large air mattress and called it a “Space Walk”.

    In 1967, Scurlock added walls. At that time, there were two inflatable fans, one for the mattress and one for the walls.

    The first real castle shaped bounce was originally designed by university students in England around 1961 for a fund raising event.

    Interesting fact: While Jumping Castles are now found all over the world, and we thank him for hours of joy, Scurlock’s finest invention was in fact the safety air cushion that is used by fire and rescue departments to catch people jumping from buildings.
