Having trouble finding a venue for a large group gathering? Private rooms are the perfect solution.

Hello. I’m the PR representative for Rakuzo—a restaurant with all-private-room seating—at the Ochanomizu Station branch.

With the intense heat wave continuing day after day, we can really feel that summer is in full swing these days. As the sun gets stronger this time of year, do you ever find yourself struggling to choose a venue for large gatherings or business dinners? In this article, we’ll introduce the appeal of our restaurant—featuring private rooms where you can relax without worrying about those around you—and how we can help solve the challenges that event planners often face.


A private space where even large groups can feel at ease

When hosting a large banquet, the most important thing is to ensure a comfortable space for all guests. Our restaurant features private rooms with sunken hearths that can accommodate up to 40 guests, making them ideal for large-scale business banquets and celebratory gatherings. The sunken hearth design reduces strain on your legs even during long periods of sitting, allowing you to enjoy conversation in a relaxed atmosphere. We also have several private rooms designed for groups of 2 to 6 people, making them ideal for small-group business entertaining or private dinners. Our all-private-room setting blocks out the surrounding noise, providing a valuable space to engage in meaningful conversations with loved ones or strengthen team bonds. Despite our location right in front of the station, the tranquility that envelops you the moment you step inside is sure to be a powerful asset for event organizers looking to maximize guest satisfaction.

The Best Banquet Package Options Based on Budget and Content

The biggest challenge in planning a banquet is striking a balance between the budget and the menu. At our restaurant, we offer a wide variety of set menus tailored to our guests’ needs. For example, if you’re looking for a casual banquet experience, the “Taste Course” or “All-Chicken Course” are ideal choices that will meet the expectations of event planners prioritizing value for money. For those seeking a more luxurious experience, the “Carefully Selected Course” and the “Four Seasons Kaiseki Course”—which features an abundance of seasonal ingredients—are popular choices. Furthermore, for those wishing to strengthen bonds over a hot pot meal, the “White Offal Hot Pot Course” and “Taiwanese Offal Hot Pot Course” are ideal, while the “Sukiyaki Course” and “Japanese-Western Fusion Course” serve as the perfect choices for special occasions. All of these courses come with a guaranteed private room, and the wide range of options to suit various budgets helps reduce the burden on the event planner.

Smooth Banquets Made Possible with All-You-Can-Drink Plans

To ensure your banquet runs smoothly, a comprehensive all-you-can-drink plan is essential. In addition to the standard 2-hour all-you-can-drink option included with our banquet courses, we offer plans that allow for greater flexibility. The “Standard” plan, featuring approximately 60 types of drinks, is a highly satisfying choice for banquets with a diverse group of guests. For those seeking a more refined selection, we also offer the “Premium” plan, which features approximately 100 types of drinks, ensuring peace of mind even when guests have specific preferences regarding alcoholic beverages. The private atmosphere of our individual rooms, where guests can freely enjoy their favorite drinks without the hassle of having to call a server for every order, plays a major role in the overall satisfaction of the banquet. We’ve established a system that allows the event organizer to enjoy the banquet themselves, without being bogged down by the details of managing orders.
