What was informed during last Music day performance was Tsuyoshi has a temporary deafness in the left ear. So, he will be hospitalized only for one week. He have to recover in his home, for now he wouldn't have permanent damage.
The issue is the whole show was recorded before the sudden deafness. The promo aired in the last 2 week of June included both kinki.
My surprise was the change on that guest apareance of Tsuyo because is pre recorded.
