Matsushimaya

I didn't take it that seriously and didn't think that the line would be so long.
When I arrived at about 9:35 on Saturday ’sunny’ morning, there were already about 40 people in line. (Japanese people really like to stand in line... ) I was glad that I was able to buy the ones I would like to buy when it was finally my turn after standing in line for about 30 minutes.

I don't like red bean paste, so I don't know what it tastes like, but the person I gave it to seemed to like it.

This shop is famous as one of Tokyo's three major daifuku.
The nearest station is about a 7-minute walk from Sengakuji Station on the Keikyu/Toei Asakusa Line. You can walk if you want to walk from Takanawa Gateway Station on the JR Yamanote Line or Keihin Tohoku Line.
I really like the balance between the softness of the mochi, the saltiness of the peas, and the red bean paste. The most famous one is Mame Daifuku, but I personally recommend Mitarashi dumplings, namako mochi (black soybeans, green laver, sakura shrimp), red rice, and seasonal chestnut steamed sweet bean jelly.
They sell out before noon, so it's best to make a reservation by phone in advance or come early.
There is usually a line, but it doesn't take long because the staff will handle it quickly.

Nice daifuku sells out quickly
