There isn’t a specific name for this time (mingling time), but…
Haru-san (@haru_wd0924), who held her wedding at THE TENDER HOUSE, calls it "Coming Photo," which I thought was lovely ♡
It’s not just mingling time,
Saying, "It’s time for Coming Photo! Everyone, please gather around the bride and groom*" adds a sense of performance and creates a cheerful atmosphere ♡
It makes it easier for the bride and groom to invite guests over saying "Come, come~ ♡" in a relaxed manner*
