This is from the time of Notte Stellata 2024, I think, but I do not recall seeing it earlier, so I think you might not have seen it, either. These pics have been taken in the Sendai Visitors Center at the Aobayama Park surrounding the Seimei castle, the Yuzu pics and stuff were there on display , I guess, in recognition of the crowds coming to the city to see Notte Stellata.
