Hello! Good morning or good evening! Yamatsuta from GP here.

In recent years, team building events aimed at bolstering employee communication and strengthening organizational unity have been gaining attention.

So this time, we’d like to introduce some of our recommended venues for holding a team building event!

Belluna Dome

First up is Belluna Dome.

Capacity: Approx. 30,000 people
Location/Access: Saitama Pref. / One-minute walk from Seibu-Kyūjō-mae Station
As a matter of fact, GP has actual experience hosting a team building event at this dome!

It was held for a major railway company.
The purpose was to show appreciation to employees’ families and to unify everyone, thereby improving organizational strength. Competitions were planned to utilize the dome structure, and screen projections were used to entertain families. It was a grand event with roughly 5,000 participants!

Tokyo Big Sight

Next is Tokyo Big Sight.

Scale: 16 exhibition halls / total exhibition area 115,420㎡ (indoor)
Location/Access: Tokyo / Three-minute walk from Tokyo Big Sight Station
We also have experience hosting an event here (in West Hall 3)! 

The event this time was for a major electronics manufacturer.
Aimed at boosting communication between employees, promoting health, and team building, hybrid competitions were held using a TV-show-style stage set to eliminate the boundary between in-person and online participants. Family participation made it a heartwarming event open to all generations.

Yokohama Arena

Next is Yokohama Arena.

Capacity: 17,000 people (indoor)
Location/Access: Kanagawa Pref. / Four-minute walk from Shin-Yokohama Station
Since its 2016 renovation, the seat fabric in the stands is designed with wave patterns, representing Yokohama’s sea. Hosting a team building event in a space where you feel like you’re in the ocean sounds wonderful. In addition, there’s excellent accessibility.
Yokohama Arena is also a famous concert venue—it would definitely become a hot topic internally if you held your team building event here!

Here’s a glimpse of an actual team building event that was held at Yokohama Arena.

This event was for a major used car company.
The photos alone convey the sheer energy and excitement that was present. The ability to create a sense of unity with such a large crowd is one of the major highlights of this venue.

Yokohama Stadium

Next, we’ll introduce Yokohama Stadium (nicknamed “Hamasta”), also located in Yokohama.

Size: 35,100㎡ (field area) – Outdoor
Location/Access: Kanagawa Pref. / Two-minute walk from Kannai Station
Having a grass field instead of concrete is a big safety plus! Safety is definitely a key point when choosing a team building venue.

Speaking of which, a team building event has actually been held here too!

The event was hosted by an internet services company. It was held outdoors in the rain, but participants gave it their all, becoming a truly memorable experience.

Ajinomoto Stadium

Fifth is Ajinomoto Stadium.

Capacity: Up to 48,013 seats – Outdoor
Location/Access: Tokyo / Five-minute walk from Tobitakyu Station
Japan’s national soccer team has competed here, and both Kouhata-san and Nitta-san have previously visited this venue. It’s a place filled with excitement.
