Tokyo Music Festival always has the 100 strong songs, so I'm hoping for another medley like 2018 and 2019. Maybe Ai no Uta & Lucky Star.
EDIT
It seems that the government in Japan will relax some of the restrictions on holding events from 19th on, so events can have around 50% attendance. Kumi's concert was filled with 30% capacity, but in the article is stated that the tour will stay with this amount of attendance restriction. Since Tokyo's dates are not available yet, I guess they are waiting to see if things get better so they can have more people, but I don't expect the production to change.
