Research & Development

Takenaka has the world’s largest state-of-the-art R&D Institute.

Never before in history, have the issues been more challenging and finding solutions more crucial. Takenaka's planners, architects, engineers and contractors must meet ever more complex client needs with increasingly advanced technologies. But such technical innovation requires two things -- imagination and painstaking R&D.

That's where the Takenaka Research and Development Institute comes in. We provide the answers.Takenaka is not just building buildings, we are building the future.
