Preparing for Natural Hazards

Radioactivity in Tokyo (Radiation levels)

The Tokyo metropolitan authorities have been conducting inspection and measurement of radioactive materials in air and tap water daily since the East Japan Earthquake of March 11, 2011, and the results are disclosed in their website. In Tokyo, all the indexes have shown radiation levels below safe limits throughout the more than two and half years since April of 2011, and conditions are considered to be safe.

A new standard for radioactive material in foodstuffs was set by the government in April, 2012. That new standard has been set with consideration for all ages, including infants and young children. Rigid inspection is carried out in the food distribution process and the results of the inspections can also be accessed through the website below.

As of September, 2013, regarding the contaminated water issue which has often been reported by the media, Prime Minister Abe announced that the government will lead the country to implement drastic measures to resolve the problem.

School Premises

According to the Regional Seismic Hazard Measurement Survey announced by the Tokyo Metropolitan Government on September 17, 2013, the level of earthquake risk in the Nampeidai area (Shibuya, Tokyo) where the school is located was as follows: degree 1 for each of the categories of collapse of building, fire, difficulty of evacuation & rescue and also degree 1 for the overall comprehensive risk. (on a five-point scale in which degree 1 indicates the lowest risk.)

The Naganuma campus is considered to be on solid (non-aqueous) ground as evident from the fact that data center facilities that require safe location are also located in the same locale,. This area is designated as “Remaining Area within the District” which indicates that the district’s high safety level eliminates the need to evacuate to other districts. All the three school buildings have been constructed as earthquake-proof, but if needed, evacuation to the park next to the school offers an alternative safety site.

School Buildings

The school buildings have quake-resistant structure. The East Japan Earthquake which recorded level upper 5 (JMA Seismic Intensity) caused no damage to any of the school buildings, facilities or equipment. The School has continued to function in excellent condition.

Emergency Supplies & Reserves

The school is equipped with emergency power generators which are able to secure the minimum electricity required in the rare event of a blackout. Likewise, the School continually maintains emergency stockpiles of such supplies as food, water, breathing masks and medical goods.

Emergency Drills

It is difficult to predict natural hazards in advance. What is important is that we can quickly and calmly evacuate to safety, coping with any difficult situation that may arise. It’s good to be prepared in our daily school life for any possible disasters. Towards this goal, and to raise students' awareness regarding emergency evacuations, the school conducts an emergency drill once every six months. The objectives of the drills are (a) to see that all understand where the safe areas are on the school premises, (b) to check the evacuation routes and sites and (c) to follow evacuation guidance and to confirm safety of all. The administration has set a goal for completion of evacuation -- from the start of evacuation to safety confirmation at evacuation site at 5 minutes.

Information Provision

School information (regarding such matters as class cancellation, etc.) are provided through our website and Facebook. We encourage students to check for information on the situation regarding the school through our sites.

Confirmation of student safety in time of emergency

The School attempts to contact students and confirm their safety in time of emergency while concurrently requesting that students contact the School through the following sites:

A. Facebook
B. E-mail
C. Telephone
03-3463-7261 (From overseas: +81-3-3463-7261)

The School maintains a data base for all student guardian/parent contacts and requires students to establish procedures for such contact in time of emergency.
