This is not unique to Shinjuku but I had to try the Sakura season donuts at Krispy Kreme. Released for spring only, the Sakura donut is filled with strawberry (not Sakura) flavour which tasted so good. The creme brulee donut at Kyoto is still the best tho. The Japanese staff was also super kind to tell us that it's not Sakura, but strawberry flavour in case we misunderstood. 🌸🍓🍩
