Case Study

Takenaka Corporation
Choosing CACHATTO as a base for BYOD*1 Remote Access
Roughly 400 years after its founding and currently one of Japanʼs most prominent general construction
contractors, Takenaka Corporation has had a hand in the construction of commercial facilities, oﬃce buildings,
baseball stadiums, and other major landmarks.
Takenaka has a reputation for relentless initiatives for R&D and technological innovation of construction technology
such as developing a building vibration control damper that possesses the world's highest damping force. In calling
our buildings "works," we feel a strong dedication to our heritage as a company that has continuously specialized
in architecture since its inception.
