Contents 1. Safety is an important mission for our railway business a) We have been working consistently to improve safety as our important mission. b) For safety investments , we have invested more than 2,200 billion yen under the past four 5-year safety plans. 2. Prevention of accidents by evaluating risks in advance a) Our present method to prevent serious accidents is mainly to prevent repeating the accidents or events that had happened. b) In the fifth 5-year safety plan , we introduced risk evaluation that takes into consideration the frequency of the events we have experienced in the past ,and the maximum scale of damage of the events we can imagine. 3. Our way of thinking about safety investments a) We will continue the present method to prevent serious accidents. In addition, we will advance the new method of before the fact prevention of accidents by risk evaluation b)We will push forward countermeasures based on the experience of the Great East Japan Earthquake disaster, taking countermeasures for a possible earthquake directly beneath the Tokyo metropolitan area. 5
