The Annual Air Show Reminder

At this time of year annually, we get treated to a mini air show in my neighborhood. Usually, we can see the Japan Air Self-Defense Force (JASDF) practicing their formation skills, starting from mid-October right up to early November. It is a reminder that the Iruma Air Show is on the way - an annual event on November 3rd in Saitama Prefecture.

In order to practice for the air show, they fly the planes in formation over my town. It starts off with just an hour of practice around mid-October, but as it gets closer to the day, they practice more. They've been practicing all day today - a photo I just took from my driveway:

Unfortunately, Blue Impulse don't practice / train in this area, but they will be at the Air Show on November 3rd. I wonder where they do train. Anyone know?
