Kyoto's summer festival, Gozan no Okuribi, is held on every August 16. This year, to prevent the spread of COVID-19 infection, the event was held on a reduced scale, and we decided to hold our annual "Daimonji Party" online. During the planning meeting using the online whiteboard "miro," we thought, "Why don't we just hold the party on miro?" and the base media of the event was decided. The main content of the event is the live streaming of the fire-letter, and the rest was planned according to the interests of each member. A variety of contents, such as original dance music  with the cursor dancing, online bar, cooking live, and online games, were arranged on the same stage of Miro, and the mouse cursor of the visitors moved around like never seen before in a Daimonji party.
