Peeping Life collaboration with Kaijuu Sakaba, a real tavern where kaijuu costumes from the Ultraman franchise are on display. Events are held where people can dine with the actors dressed in the kaijuu costumes.

This Peeping Life collaboration was in honor of Kaijuu Sakaba's grand re-opening in Kawasaki and opening of a second tavern in Osaka and focuses on the kaijuu's daily lives outside of fighting Ultraman.
