Super Big! “Mammoth Coffee” came to Yaesu from Korea!

2026.01.13

The charm of the Yaesu, Nihonbashi, and Kyobashi area is that you can find delicious food from both Japan and abroad, and you can choose a restaurant according to your purpose and mood. GOKINJYO, a community of women workers in this area, introduces their favorite dishes in this relay series.

Hello, my name is Nikaido! I am Nikaido, a comedian in Yaesu Nihonbashi Kyobashi, in my third year at Yoshimoto Kogyo!

Nikaido heard a rumor…a popular Korean coffee chain, Mammoth Coffee, opened in Yaechika in December.

 

Nikaido loves Korea! We went there last year!

However, I have actually never been to Mammoth Coffee. I never thought it would be possible in my home, Yaesu! I must go there as soon as possible. If Nikaido doesn’t go, who will! With that in mind, I went to the show!

 

Mammoth Coffee suddenly appeared in one of the rows of Yaechika’s Hokkaido product stores.

We went on a weekday night and there were at least 10 people in line! That’s amazingly popular! Also, so many young people! Could it also be a hot topic on social media?

It is a take-out specialty store, so even if there is a line, the turnover is fast! I think it was also about 10 minutes from purchase to pick up…?

Nikaido purchased a… Honey Americano.

I was able to add cinnamon for free, so I did!

Look at the size! This is the L size, and the price is 450 yen for a 940ml bottle.

Oh, that’s too cheap!

By the way, even the S size has 410 ml. Other coffee chains are around 200 to 300 ml, so you can see how mammoth they are.

I took it home and drank it…delicious!

I also added cinnamon and the cinnamon, honey and coffee flavors match. It makes my brain clear!

But, however, the quantity is a lot!

Nikaido drinks while eating sweets and…

Drink while you work or…

It took me about two hours to finish it, drinking it after my bath!

By the way, if I held it all the time, my arms usually hurt! For the first time in my life, I might get muscle aches from coffee!

 

The person who recommended the mammoth coffee told me that she bought it in the morning before work started and finished it at 2:00 p.m.! She carried this big coffee with her all the way to the conference room.

Since it was built right next to Tokyo Station, maybe you can buy one before work or before taking the bullet train or bus!

Nikaido bought a large size, so it was crazy big, but don’t worry, there are usually S and M sizes as well.

While writing this article, I realized for the first time that the store is called “Mammoth Coffee” because it sells big coffee! Did you notice it, too?
