There are also "Delicious OTO" corners collecting sounds related to food, and "World OTO" gathering exotic sounds, displaying sounds from various perspectives. It's an exhibition where visitors can encounter new charms of sound from various viewpoints, not just by listening to sounds, but also from daily life, the history of sound, and even unexpected commonalities between sounds.

Experiential Exhibition "OTO MART" Concept

OTO MART is an "audio supermarket."

It is an experiential exhibition of "sounds" that collects various "sounds" from around the world.

The bark of a giraffe. The sound of a saxophone. The sound of a fart.

The sound of panicking when you carelessly put a plastic bag down and find an egg carton inside...
