The ninja planning exhibition 'SiNoBi' is held at Kashiwazaki Yume no Mori Park in Niigata Prefecture as a playground for children to move, think, and learn. At this event, you can experience ninja training through activities such as slacklining, wall climbing, and giant acorn searching. Additionally, there are exhibitions introducing the lifestyles of ninjas during the Warring States period, offering historical insight. In January, special events such as a cardboard maze and mystery-solving are also held. At the venue, ninja costumes can be rented, creating an authentic ninja feeling. There are various ways to enjoy, such as photographing and shuriken throwing experience. By wearing ninja costumes, you can refresh both body and mind while enjoying the activities. This event is free to attend, making it highly recommended for parent-child participation. Taking photos in ninja costumes, in particular, is sure to make wonderful memories.
