Hatena Coffee continues to make customers smile as they scratch their heads.

The line that separates cafes from regular restaurants can be a hazy one, but most people would say that cafes generally have a more relaxed vibe that encourages you to linger over your drink or meal. And it’s definitely true that Hatena Coffee, which just arrived in Osaka’s Namba neighborhood, isn’t going to pressure you to hurry up and leave. As a matter of fact, Hatena Coffee has a policy in which they won’t even let you go home until you’ve proved your smarts.

The cafe’s name is a tipoff to this unique rule, as “hatena marks” are what question marks are called in Japanese. In addition to beverages and light fare, Hatena Coffee also serves up brain-teasing puzzles. There’s a selection to choose from, with varying difficulties, and solving the puzzle is an official requirement in order to be allowed to leave.

That might sound like the place is an escape room that you can eat and drink in, but Hatena Coffee takes the opposite approach to time. In an escape room you’re given a certain amount of time in which to try to solve the mystery, and when time’s up, you’re let out regardless of whether or not you succeeded. At Hatena Coffee, though there’s no time limit, so you can approach the puzzle at whatever pace feels fun and enjoyable to you…or to you and your date or friends, since the Namba cafe has three types of seating: counters for solo customers, two-chair tables for pairs, or four-chair tables for larger groups.

All of the cafe’s puzzles are produced by Tokyo-based puzzle/mystery design company Experiful. The estimated time needed to solve most of them is in the range of 30 to 60 minutes, but if you want even more mental stimulation, the tougher ones will take up to 90 minutes, the company says (and while not explicitly stated, we’re sure that if you’re really stumped, they’ll let you go home without solving the puzzle, if you ask nicely).

Each guest pays a 1,500-yen (US$9.70) “puzzle fee” and is asked to also order at least one drink, but there’s no timed seat/table charge at Hatena Coffee, so you don’t need to worry about running up a more expensive tab if it takes you an extra-long time to solve your puzzle. Drinks are all priced at 500 yen (whether soft drinks or alcoholic), while snacks start at 500 yen, sandwiches and pasta plates at 700 yen, and desserts at 1,000 yen.

The Namba Hatena Coffee’s grand opening is scheduled for June 1, when it will become the chain’s sixth branch, joining the three locations in Tokyo (in the Ginza, Shinjuku, and Ikebukuro neighborhoods), one in Yokohama, and one already open in Osaka’s Umeda neighborhood. With barely more than a year having passed since the initial branch opened in Yokohama, the fast expansion seems to show that there’s an eager market of fans for puzzles in relaxing spaces, and the new branch should make a great place to visit for a coffee after trying the neighborhood’s innovative sushi pizza.
