Plus Alpha Consulting — Tokyo: a Red Room for heated debate and a vending machine that never asks for coins

Plus Alpha Consulting moved its head office in March 2022 into a floor with no walls at all. It named its meeting rooms after colours and fruit, and it calls its two branch offices “the Dreaming Branch” in Osaka and “the Cherry-Blossom Branch” in Fukuoka.

Concept

Colour-coded rooms, and no walls in between

The Tokyo office works on a single flat floor without any walls, and without a president’s office — the company says anyone can simply walk up and talk. The walls that do exist belong to the meeting rooms, and each of those is a colour.

The Red Room is “the red of passion”, where heated discussions sometimes happen. The Orange Room has a big monitor and bright wallpaper. The Peach Room has the view from a high floor. The one room with a name instead of a colour, Mim Lab, is described as having the best view in the company.

01 · Entrance

A sofa chosen for its shape

The entrance is bright and open. Guests wait on a sofa whose form, the company says, was a deliberate choice.

Red, Orange, Peach

Three colour rooms sit side by side. Beyond them, three presentation rooms are normally divided but can be opened into one large space.

03 · Refresh room

Lunch, games and events

The refresh room does everything: people eat lunch here, play to take a break and hold events. Part of it looks outside, for a rest with a view.

04 · The perks

Press a button, get a drink

The company’s best-known perk is a vending machine that gives drinks for free — just press. The menu changes regularly, and it is described as the benefit staff rate most highly.

Nearby is a massage chair. It is so comfortable, the company admits, that some staff fall asleep in it.

05 · The office

One floor, nobody behind a door

The work floor itself is completely flat and open. Mim Lab, a special meeting room, looks out over the city.
