A Surprising Hideaway! What Are the Unexpected Ways to Use Private Rooms in Shinjuku?

Hello. I’m the PR representative for Rakuzo—a restaurant with all-private-room seating—at the Shinjuku East Exit location.

Now that the height of summer has passed, a hint of coolness has begun to mingle with the evening breeze. Today, we’d like to tell you about our restaurant—a space that’s surprisingly serene despite being nestled amid the hustle and bustle of the big city of Shinjuku—and the appeal of our banquet plans, which are a hidden gem known only to those in the know.

 

Unexpected tranquility in a completely private room right in front of Shinjuku Station

Although located in the Shinjuku Station East Exit area—which is always bustling with people—the moment you step through our doors, you’ll find yourself in a surprisingly serene atmosphere. Our greatest strength is that every seat is in a private room, allowing you to enjoy your own private time without worrying about prying eyes or background noise. This serene environment adds immense value to important business meetings or moments spent with loved ones when you want to converse freely without worrying about those around you. Located right in the heart of the city, yet offering a sense of calm reminiscent of a hidden retreat, this space is so immersive that many guests tell us they “forget they’re in Shinjuku.” The private, door-enclosed spaces enhance the quality of your conversation and help you relax deeply.

 

Versatile sunken kotatsu seating that adapts to the number of guests

Another unexpected charm of our restaurant’s interior design lies in its flexibility. We offer a wide variety of options, ranging from private rooms for two to those for four, six, eight, ten, and twelve guests, as well as private rooms with sunken hearths that can accommodate up to 30 guests. The sunken kotatsu seating, in particular, allows guests to stretch out their legs, making it less tiring even during long stays and enabling them to enjoy their meal in a relaxed posture. From small gatherings to department-wide company banquets, we can recommend the private room with the ideal size for your group, making it highly convenient for event planners. By adjusting the size of the space, we can maintain a comfortable sense of togetherness regardless of the gathering’s scale.

 

Smart Pricing for All-You-Can-Drink Course Menus

When planning a banquet, budget management is likely one of the biggest headaches for the event organizer. At our restaurant, all set menus include a 2-hour all-you-can-drink package, and we offer a wide variety of plans with discounted rates. For example, you can choose from plans tailored to your specific needs—ranging from cost-effective options like the “Guaranteed Private Room” [Taste Course] and “Guaranteed Private Room” [Chicken Specialties Course] to more luxurious offerings such as the “Guaranteed Private Room” [Four Seasons Kaiseki Course] and “Guaranteed Private Room” [Japanese-Western Fusion Course]. In addition, we offer standalone all-you-can-drink plans—such as 《Guaranteed Private Room》【Standard】 and 《Guaranteed Private Room》【Premium】—allowing you to flexibly combine options to fit your budget. The ability to host banquets at transparent, reasonable prices while enjoying the added value of a private room is a major advantage unique to our restaurant.
