They cleared us off the field and started pulling the balloons down, so my photos are a little out of order.
We also went for Balloon School. Balloon School consisted of opening the field of balloons up for school children and the rest of us folks to learn a little about how balloons operate. There were teams from all over, so you're bound to find a language you understand.
See the white one above? That's Asimo! Asimo is a robot made by Honda and paraded around at Miraikan.
Those balloons were tethered and going up and down.
Don't forget to have your picture taken in this balloon set up!
If you go.... there are parking lots set up in Saga with free shuttle buses to the event. If you decide to drive yourself to the event, prepare to walk! It's 1,000-yen to park... and it's not all that close.
