Sorry if this is not an appropriate place to asked this.
I was was in Osaka Castle today and couldn't help but notice loads of people doing the same pose in roughly the same location (near the vending machines to the left, when looking at the front of the castle).
I have looked online bit can't find any info as to what they are doing it for. Is it simply an tiktok trend? Or is it something more significant.
TIA.
