Mission and Challenge: Artizon Museum Entrusts Its Collection to the Future
Initiative to protect against possible disasters
With the frequent once-in-a-century-class natural disasters in recent years, conventional ideas are no longer adequate to cope with disasters.
The Museum Tower Kyobashi was designed with the utmost consideration for its business continuity plan, in addition to convenience and comfort.
Base isolation structure capable of withstanding intensity 7 earthquakes
As a countermeasure against major earthquakes, seismic isolators and dampers are installed underground to provide a base isolation structure, enabling the skyscraper to withstand intensity 7 earthquakes (the maximum on the Japanese seismic intensity scale).
- Base isolation layer under the first basement level absorbs the vibration energy from earthquakes, reducing vibration of the building
- Highest-class in Japan to reduce vibrations to 250gal or less, which can even withstand major earthquakes, equivalent to the Great Kanto Earthquake
- Base isolation structure can withstand an intensity 7 earthquake, enabling continuous use of the building
-
- Earthquake-resistant
- Distortion of columns and beams absorbs the vibration energy from earthquakes (vibration is the largest of all)
-
- Vibration control
- Vibration control dampers absorb the vibration energy from earthquakes (less vibration than the earthquake-resistant construction, but the upper floors experience more vibration)
-
Museum Tower Kyobashi
- Seismic base isolation
- Base isolation device absorbs the vibration energy from earthquakes (least vibration)

Emergency generators to supply 100% power for 72 hours
The Museum Tower Kyobashi has established a secure system that enables business continuity planning to prepare for inevitable natural disasters.
- Essential facilities (substation facilities, emergency generators, and heat sources) are placed on the 8th and 9th levels above ground to maintain building operations unaffected by flooding
- Two emergency generators can supply 100% power to the entire building for 72 hours in case of a power outage
State-of-the-art system for 24/7 safety and security monitoring
Control Center of Museum Tower Kyobashi
The building integrates a system that immediately determines the degree of damage to the building after an earthquake. In the event of an emergency, it assists in the rapid restoration of building functions.
- Storage for disaster prevention & emergency supplies
- The Museum Tower Kyobashi’s storage for disaster prevention & emergency supplies holds a three-day supply of emergency food and drinking water for people having difficulty returning home.
