Someone also posted that the fact that she posted a video herself in cherry blossom gardens in full bloom indicates that she did travel to the North and is no longer in Tokyo, since cherry blossom season is long over there at this point
Ooh thank you for pointing that out - I completely forgot about the cherry blossom calendars! According to this, Tokyo's full bloom dates were from mid-March to early-April and the season ended on the 6th. Aomori's are from mid-April to early-May. It started on the 17th and is currently in full bloom. Considering that she got into Japan in early April, that would suggest that the video was taken in the north.
