As people get older their throat function declines. It becomes more difficult to breathe and to swallow food. The best way to recover throat function is increased vocalization. However, the rehabilitation for this is not fun at all, and therefore the elderly reluctantly used their voices at Geriatric health services facility HITORIZAWA.

We first launched "TON-TON VOICE SUMO" on 27/1/2016, at generic health services facility HITORIZAWA. On this day, about 20 people enjoyed the rehabilitation. Second implementation was on 29/2/2016 at the same place, and at this time more than 60 people played, including not only elderly but the staffs who work at the facility. Kounandai Hospital and Heart-warm Clinic are scheduled for the next implementation.
