The Saga International Balloon Fiesta is one of the biggest events in Japan held along the Kase River in the Saga Prefecture and this year is the 22nd year of the FAI World Hot Air Balloon Championship. Every year in late October to early November, the event gathered more than 100 hot-air balloons and 800,000 visitors from around the world. It is simply amazing by looking at the colorful balloons floating in the skies of Saga.
