◆What is "Hatena Coffee Shop"?
Hatena Coffee is a relaxed mystery-solving cafe where you can enjoy a cup of coffee in a stylish interior . Whether you're alone or with two people, the casual atmosphere makes it appealing; no reservations are required and you can just drop in and play. Unlike an escape room experience, there's no time limit, so you can enjoy solving puzzles at your own pace with a drink in hand . However, once you enter the cafe, you can't leave until you've solved the mystery! Take your time and think long and hard to arrive at the one and only truth.
All of the puzzles at Hatena Coffee are completely original creations by Experiful, an experiential entertainment planning company. Utilizing the know-how they have cultivated over the years, they offer easy-to-play, satisfying puzzles .
They will toy with you with various tricks, such as opening locked treasure chests, making use of unusual items, and ◯◯ing trap-laden ◯◯. (The initial titles will be mainly aimed at beginners, but we plan to expand the range.)
◆ "Can you solve this mystery?" A hot topic at X even before the store opened
Approximately 100,000 impressions in one day
The first store, Hatena Coffee Yokohama Station Branch , is a mystery-solving cafe, so the opening information was posted on the official X website with a riddle attached ( https://x.com/tanteicamp/status/1900126686424998098 ) . As a result, it received a huge response of about 100,000 impressions in just one day! Even before the opening, there were many voices of anticipation .

Within a month of opening, the Yokohama Station store had over 500 customers, and the second store, the Tokyo Shinjuku store, had over 800 customers , with many people enjoying the casual cafe mystery.
◆Opening on the symbolic day of Coffee Day and Tokyo Citizens' Day, with wishes in mind!
The Hatena Coffee shop that opened in Yokohama was so full that there were days when customers had to wait two hours to get in , so in order to expand the store, they decided to open a third store in Ginza . With the desire to deliver their specialty coffee to people in the Tokyo area, they decided to open the Ginza store on October 1st (Coffee Day, Tokyo Citizens' Day) .
We'll be waiting for you with some easy puzzles and hot coffee.
