Mitsui Fudosan — Nihonbashi: a headquarters designed to make people cross paths

Mitsui Fudosan moved into the Nihonbashi Muromachi Mitsui Tower in 2019 to speed up two things: innovation and a change in how it works. The office is planned around one word, CROSSING — internal stairs and a promenade on every floor, meeting at points where people are meant to run into each other.

Concept

Vertical and horizontal

Internal stairs at the north and south ends of every floor make a vertical flow; a promenade running around each floor makes a horizontal one. Where the two meet, the company puts a CROSSING area.

Each CROSSING area keeps the same purpose but is given a different design, so that choosing where to sit means moving between floors — and running into people from other departments on the way.

01 · The four areas

Camp, Port, Campus, Park

The CROSSING areas are named Camp, Port, Campus and Park. Each has its own character, which is what pulls people out of their own floor.

02 · Work floor

No one owns a desk

The work areas are all free address, designed so that people can pick the kind of place that suits the task — and so that colleagues from across the company end up working side by side.

03 · Café & lounge

Two places that are not desks

CAFE Crossing and the hotel-like CROSSING Lounge give the building places to work that feel nothing like a work floor.

04 · Meetings

Rooms with different designs

Meeting rooms are deliberately varied in design, so a conversation can be matched to a room rather than the other way round.

05 · Health

A meditation room, a gym, a healthy lunch

The company treats the five senses as part of the plan: greenery, colour, light, ambient sound, scent and texture, plus services around them. There is a meditation room, a fitness facility in the building, and a healthy menu at the café and pantry. Staff can also use shared services in the tower, including the members’ lounge and the WORKSTYLING shared offices.
