When I was there around in May, I saw mini anjou at Isetan. Only 2 colors, one has “Love” print and another in red.
In contrast, mini anjou or any anjou for that matter was not available in Takashimaya.
It’s not that common, but do try.

The Goyard lines are insane and I wished I knew these things!
On the positive, Japanese Yen currency as of May was unbeatable! Probably Goyard was even cheaper in Tokyo vs Europe and way cheaper vs US.
I went to the stores in Tokyo last August and I didn't have any issue getting either store. Slight queue of about 15-20 minutes at Nihonbashi but much better stock of items. Was deciding between the Boeing 45 and the Artois GM. I know it was insanely hard to find the Boeing 45 in any color at all so I took the black one (and I've grown to love it).
Kyoto and Osaka stores had good stock and NO line at all FWIW.
