01 · The short answer
Open floors, with no partitions
Rakuten’s headquarters in Futako-Tamagawa is the clearest version: desks have no partitions, so “shall we talk about it now?” is always possible.

02 · At scale
NTT DATA, building by building
NTT DATA runs the same idea across a headquarters for thousands of people. Work floors have no partitions, and the company is rolling out clean desks and free-address seating.

03 · The reason
Seeing what others are doing
At The Asahi Shimbun in Nagoya there are almost no partitions, and the designers say that is the point: when you can see what the people around you are working on, conversation starts by itself.

04 · The halfway version
Free address within a team
Not every company goes all the way. OEC in Oita uses “group free address”: each team has its own area, and inside it people sit wherever they like.
