Safety & Security #1

Protecting Your

A true security system
both keeps you safe and
gives you peace of mind,
by thoroughly protecting
without ever drawing
attention to itself.

Multi-level security

Anyone entering the building must pass through four*1 security checkpoints: at the building entrance, in the elevator hall, in the elevator, and at the front door.
Residents-only entrance and elevators
The building has been designed so that Suite and Sky Suite residents may enter via exclusive entrances and go up to their homes via elevators available only to them. Staff who are fluent in both English and Japanese are stationed at the 1st and 42nd floor reception desks 24 hours per day.
Remote keychain
To allow residents to pass through security without hassle, they are provided with remote keychains that can unlock each security feature—as well as the front door—from within a handbag, pocket, or other similar location.
Progressive door locks
The front door of every residence features a progressive lock that provides a very high degree of security. With 100 billion possible key patterns, this type of lock is virtually impossible to pick. It also incorporates an extremely resilient material that cannot be easily drilled through.

24-hour safety and
security network

The building has a dedicated safety and security center where staff monitor every area in the building 24 hours per day, 365 days per year. In an emergency, the staff will work with reception staff—also on hand 24 hours per day—to swiftly respond to the situation. Residents may contact our safety and security staff via the intercom at any time to discuss any needs or issues.
Security sensors
The front door of every residence is equipped with a security sensor. When switched on, the sensor immediately contacts the onsite safety and security center via the intercom if the front door is opened.
Video intercom
The intercom displays video of anyone calling from the building entrance or from outside the front door, allowing you to immediately identify the visitor and stop anyone suspicious from entering or prevent unwanted solicitations. The intercom can also be synced to your smartphone.
  • 1: The number of checkpoints will vary depending on the time of day and route to your residence. 2: On occasion, the smart lock may be unable to detect your keychain due to bad reception or low battery. If this happens, place the key head within three centimeters from the sensor to unlock. 3: On occasion, the electric lock may be unable to detect your keychain due to bad reception or low battery. If this happens, press the OPEN button while placing your key head within three centimeters from the front door sensor to unlock. In an emergency, you can access the mechanical key stored inside the keychain to manually unlock the door.

Earthquake resiliency
A high level of safety
is particularly essential
for a high-rise residence.
Earthquake resilience
has been implemented in
the building and elevators
to an exceptional degree;
evacuation procedures
in case of fire cover
every possible scenario.

Three layers of
earthquake resiliency

Swaying caused by even the biggest quakes is reduced through the viscous dampers,
friction wall dampers, and active mass dampers incorporated in the building.
This design also mitigates swaying caused by wind and other factors,
ensuring comfort even in the upper floors.
Viscous dampers
These devices contain a viscous substance that allows them to absorb energy from shaking to reduce its impact, whether from modest swaying caused by strong winds and small earthquakes or violent shaking caused by larger earthquakes.
Friction wall dampers
Composed of a moving wall sandwiched between two fixed parts, these dampers absorb some of the energy of an earthquake through the friction created when the wall slides between the two fixed parts. These dampers are effective in reducing the impact of swaying caused by mid-sized and large earthquakes.
Active mass dampers
A series of weights installed in the upper floors is controlled with a linear motor to provide stability in the face of strong winds. They also aid in rapidly curtailing the swaying that results from an earthquake.

Elevators built with the highest level of earthquake resiliency

Toranomon Hills Residential Tower is equipped with elevators that are certified S09*1—the highest level of earthquake resiliency in Japan. Safety measures have been implemented to prevent a wide range of situations, from being trapped in an elevator to the power shutting down during an electrical outage.
1: Resiliency levels are defined in guidelines for designing and constructing earthquake-resilient elevators, revised in 2009 to enforce stricter guidelines, published by the Japan Building Equipment and Elevator Center Foundation.

Evacuation procedures incorporating emergency elevators (TBC)

In principle, usage of elevators is forbidden during a fire in Japan. However, with proper permits from the Tokyo Fire Department, we will be allowed to evacuate elderly and disabled residents from the building via elevator.

Protecting Your

Life continuity planning
Continuity is important
following a disaster.
We have taken every
precaution to ensure
your life is not disrupted
when disaster strikes.

Emergency lifeline

The building is equipped with an emergency power generator and a large water tank, which together can provide about three days of electricity and water in an emergency even if public utilities are cut off. Additionally, residences are supplied with medium-pressure gas—a type of gas that is resilient to earthquake effects—to allow as little disruption to your life as possible following a natural disaster.
Emergency generator
Medium-pressure gas
Resilient to earthquake effects
Emergency well
For household use only; not for drinking
Water tank
140 ㎥, or three days’ worth of water
Emergency sockets
These allow electric appliances to be powered by the emergency generator even after the power has been shut down following a natural disaster.
Emergency lights
These will be powered by the emergency generator in case the power goes out.
Ceiling speakers
These are installed in all residences and common areas to announce emergencies and explain evacuation procedures in the event of a natural disaster. All speakers can function even when the power is out.

Quick resumption of
elevator operations

When the elevators stop due to an earthquake, they are automatically inspected for damage. If no signs of damage affecting their operation are found, the elevators will automatically resume moving*1 even before repair workers have arrived. In this way, the elevators are prevented from remaining non-operational for long periods of time.
Water barriers
In case of violent rain, water barriers will be quickly set up at all entrances and openings to prevent flooding in the roads from entering the building.
Emergency wastewater tank
In case of failure in the water system, a valve is turned to redirect wastewater to an onsite tank that that can collect about seven days of wastewater.*2 Meanwhile, although the toilets in the residences are tankless, they are designed so they can still be flushed with a lever even during a power outage.
Emergency kit
Every resident is issued an emergency kit upon occupancy.*3 Items include a water tank, a portable toilet, and other essentials that you will need while you await rescue in your home.
Emergency food and water supplies
The building will feature one food and water storage unit for every three to five floors, ensuring enough supplies to last for three days for all residents in an emergency.*4
  • 1: Elevators will initially move at a slower pace. Once repair workers have inspected the elevator system and determined its safety, operations will resume at a normal pace. 2: The tank may be used for longer provided it is periodically emptied by vacuum tankers and properly cleaned and disinfected. 3: You will be issued one emergency kit upon receiving the keys to the residence. No further kits will be issued. 4: Supply volumes, types, locations, and other descriptions may change.

A Neighborhood
that Protects

Safety measures for our Hills community
In case of emergency,
we will immediately form
a task force that utilizes
an emergency response
network covering all
of our developments,
so that we can ensure
the safety of our residents.
Mori Building Emergency Response Network
  • HQ
  • Safety & security centers

Your place of
safety and shelter

The high level of emergency preparedness in Residential Tower extends to the rest of Toranomon Hills—and to nearby Mori Building developments as well. During a disaster, the developments form an emergency response network headquartered in Roppongi Hills, ensuring that everyone in the vicinity can safely take shelter. Knowing this robust framework is in place, you can always go about your day in the neighborhood with peace of mind.

A rapid response
emergency task force

Typical business hours account for only a fourth of a year—which makes it important to be able to respond swiftly to earthquakes during the other three fourths of the year. When an earthquake occurs,*1 about 1,400 employees of Mori Building become part of an emergency task force that works on swiftly repairing damage and providing the support you need to maintain your lifestyle and business.

Disaster training for staff

Even the most comprehensive emergency planning will fail without complete trust between rescuers and those who require rescuing. This is why we place so much importance on our receptionists and other employees building strong relationships with our residents through their daily interactions. Furthermore, Mori Building conducts a large-scale earthquake drill every six months for all employees. Meanwhile, key emergency staff are required to attend six drills that the company conducts every year, and all employees are required to be certified in emergency first aid and CPR. By continuously training our staff in this way, we ensure they can respond calmly and swiftly in an emergency.
