宴会のご案内Host your company trip banquet in Shinjuku.
Take off your shoes, relax, and unwind. Experience an evening reminiscent of a traditional Japanese inn (ryokan) in the spacious banquet halls of Genkai.

IntroductionAre you creating opportunities to deepen communication within your team and improve your organizational culture?
Unlike in the past—when company trips were the norm—organizing such events today has become more challenging, whether due to coordinating schedules, managing costs, or ensuring high participation.That is why Genkai offers the perfect solution: an experience just like a banquet at a traditional Japanese inn, right here in Shinjuku.
Reasons for Choosing UsThree reasons to choose a banquet at Genkai

1. Take off your shoes and enjoy the atmosphere of a traditional Japanese inn
In our authentic, Japanese-style banquet halls, you can take off your shoes and relax on the tatami mats. Stepping away from the daily office environment helps ease formal tensions, making it natural to strike up conversations with colleagues you might not otherwise interact with.
2. Private rooms allow for easy movement and interaction
Because you are in a private space, you don’t have to worry about those around you. Feel free to walk around, pour drinks for others, or engage in deep conversations across different departments—just like at a traditional inn. Many event organizers choose us because our space helps bridge the gap between superiors and subordinates, as well as between long-standing and new team members.
3. We can assist with event programming
We are happy to help you plan activities to liven up your banquet, such as awards ceremonies or entertainment.
