Building Safe and Resilient Infrastructure
Ensuring safe and reliable transportation is a prerequisite for all business development and marks the foundationof the railway business; therefore, we have consistently given top priority to this issue. Specifically, with regard
to the Tokaido Shinkansen as the main transportation artery of Japan and the conventional lines as social
infrastructure, we are building a safe and resilient infrastructure by promoting various safety measures in both
physical and non-physical aspects to support Japan’s economic and social activities in a sustainable manner.

General Principles of Safety
JR Central has the General Principles of Safety as the basic spirit for
employees involved in transportation safety. It was established following
a 1951 accident at Sakuragicho Station on the Keihin-Tohoku Line while
we were operating as part of Japan National Railways. The principles
specifically state that the correct mindset and moral awareness andattitude are needed for all employees to do their utmost to ensure
safety and protect human lives above all else, regardless of their job
responsibilities, because the railway business is an important service withthe responsibility to safeguard precious lives and assets.
As a result of various safety efforts, especially the Tokaido Shinkansen

Under the philosophy of the General Principles of Safety, we establishedthe“Basic Approach to Safety”and are abiding by it. We maintain safety
through“people,”“structure”and“equipment,”and what forms thebasis is the culture of prioritizing safety. The diagram on right describes a
structure whereby a culture in which safety is prioritized above anythingelse is firmly established and all individuals practice safety-first behavior,
upon which each of the three elements of“people,”“structure”and“equipment”support safety.
The first pillar of“people”represents ongoing efforts to enhance theability of employees to detect risks and changes and deal with themwithout fail on their own initiative, and the ability to deal with difficult
situations through effective education and training.
The pillars of“structure”and“equipment”respectively represent
ongoing efforts to ensure adherence to, and review,“structures,”including
rules and handling, by accurately grasping situations on the ground fromthe correct perspective regarding safety and looking into weaknesses
based on changes in the environment, signs and lessons learned fromline, which has been used byabout 6.8 billion passengers, has
had no accidents resulting in thedeath of passengers since the startof its operation in 1964. We willcontinuously work to maintain safeand reliable transportation as our
top priority, aiming to achieve it ateven higher levels

Safety Audit
Safety audits are conducted at JR Central’s business organization andaffiliate companies to prevent train accidents and labor accidents. These
audits are performed based on three basic policies: confirmation of
the level of compliance with laws and regulations, etc., confirmation of
measures in place to prevent train and industrial accidents, and preventionof recurrence of the kind of train and labor accidents whose details havebeen investigated. In audits, we verify the actual status of daily operations
by checking sites where work is being carried out and the documents
related to inspections, construction, etc., and share the results. Throughthese audits, we are working to prevent violations of laws and regulations,the forgetting of past countermeasures in response to past accidents, andlapses of rules before an incident occurs.

Initiatives for Human Resources to Ensure Safety
In order to maintain safety it is essential, as the basic premise, todevelop human resources with high technical capabilities, a strong will, andthe correct values to support safety. In developing human resources, we
believe it is important to observe our own rules “discipline”(), to maintainand improve quality and prevent accidents “technical(capability”), andto gain a“sense of unity”by collaborating and cooperating with related
employees and by fulfilling personal responsibilities. Focusing on theseissues, we are engaged in employee training and education.

Capital Investment for Safety
JR Central has actively implemented capital investment related tosafety since its establishment. In the 36 years up to FY2022, we havemade safety-related investments totaling over 4.4 trillion yen, including
safety measures such as updating the Automatic Train Control (ATC) on
the Tokaido Shinkansen, and introducing ATS-PT (Automatic Train Stop)in all of our conventional lines, as well as disaster prevention measures
such as seismic reinforcement, improvements in electrical equipment,
replacement of rolling stock, and the introduction of efficient andeffective inspection machines and systems.
In FY2023, we will continue to place top priority on ensuring safeand reliable transportation, which is the starting point of our railway
business. In order to further reinforce structures along with earthquake
countermeasures, JR Central will pursue derailment and deviation
countermeasures for the Tokaido Shinkansen by implementing
derailment prevention guards for the entire line. We will also proceedwith the seismic reinforcement of platform sheds, the implementationof measures to prevent suspended ceilings at stations from falling in theevent of an earthquake, rebuilding of the Nagoya rolling stock repair andinspection depot, and reinforcing the quake resistance of elevated trackcolumns of conventional lines, etc. Furthermore, we are conducting
research and design work in preparation for the installation of automatic
platform doors in all Shinkansen stations and, for conventional lines, areadvancing the work to install such doors on Platforms 5 and 6 (outboundTokaido line) and Platforms 7 and 8 (Chuo line) at Nagoya Station. As

CENTRAL JAPAN RAILWAY COMPANY Integrated Report 2023

For the Tokaido Shinkansen, we are promoting derailment and deviation
countermeasures to prevent the expansion of damage from derailment
caused by an earthquake. We are working to introduce such measures
as installation of“derailment prevention guards”which prevent vehicle
derailment to the extent possible.
We expect to complete theimplementation of these measures on
the entire line by FY2028.“Deviation
prevention stoppers,”which preventa major derailment of rolling stock inthe event of a derailment, have alreadybeen installed on all of the rollingstock running in our service area.
Derailment prevention guards

We have been implementing earthquake-resistance measures for various
civil engineering structures and buildings so as to prevent Shinkansen
services from being suspended for a long period of time in the event of anearthquake. Furthermore, starting in FY2021, we are implementing seismic
reinforcement of platform sheds.

reduce the stopping distance at the time of an earthquake. For the N700S,
which we launched in July 2020, we made improvements to the ATC andthe brake system to further reduce the stopping distance by roughly 5%
compared to the stopping distance of the N700A (3rd edition).

Historical number of railway crossings and crossing types

037Structural Reinforcement*After introducing the “Urgent Earthquake Detection and Alarm System (UrEDAS)” in 1992 aheadof other companies, we continued to further accelerate the speed of the alarm by introducing the“Tokaido Shinkansen Earthquake Rapid Alarm System (TERRA-S)” in 2005 and started utilizing
information from the Seafloor Observation Network for Earthquakes and Tsunamis in April 2019.

A particularly important factor for improving the safety of Conventional
Lines is measures to prevent accidents at railway crossings. We areworking to install crossing gates, crossing obstacle detection systems,
etc., and are taking such drastic measures as eliminating crossings by,for example, elevating the tracks, for which we negotiate with local
governments. As part of effort to prevent crossing accidents, we arealso actively working on activities to raise awareness, including crossing
accident prevention campaigns.

Crossings are classified by the equipment they have into three types:
Type 1, which has crossing gates and alarms, Type 3, which has only
alarms, and Type 4, which has neither gates nor alarms.
Work to upgrade Type 3 and 4 crossings into Type 1 is under way,considering such factors as the amount of road traffic, the amount ofrailway traffic, and the situation surrounding the crossing.

Large-scale Renovation

Our civil engineering structures are sufficiently maintained throughthorough daily inspections and repair. However, in future, it will be
inevitable to replace many of the facilities due to aging. We received theapproval of the Minister of Land, Infrastructure, Transport and Tourism forour allowance reserve plan for the large-scale renovation of Shinkansen
infrastructure for the Tokaido Shinkansen based on the Nationwide
Shinkansen Railway Development Act, and began building the reservefrom 2002. Along with this, we have advanced our research on a new
construction method, led by our Komaki Research Center. As a result of
our R&D efforts, we developed a new construction method that allows us
to significantly reduce the impact on train operations during construction
work, and to considerably cut construction costs. With this method inplace, JR Central began the renovation work in FY2013, ahead of theoriginal schedule. In construction work, we begin with the implementationof measures to extend the life of structures by inhibiting the occurrence of
cracking and other damage from aging (measures to inhibit aging damage)and, if necessary, overall renovations such as the replacement of girders

For cases in which a vehicle obstructs a crossing, we install crossing
obstacle detection systems that can detect stuck vehicles using
infrared or laser beams, and systems that can issue an alert if thecrossing gates do not close. If the crossing detects an abnormality,
the related signals are made to indicate“stop,”and trains are madeto stop before they reach the crossing. Starting in FY2022, we havebeen introducing a high-performance laser sensor crossing obstacle
detection system, which has better performance at detecting
pedestrians, bicycles, wheelchairs, etc., at crossings where train traffic

Initiatives to stop trains quickly
Information from the aforementioned earthquake disaster prevention
system will be used to detect initial weak tremors in case of anearthquake, and provide a warning to the driver’s cabin of trains travelingin segments that are likely to be impacted significantly by the earthquake,
instructing the driver who receives the warning to apply the brakes
immediately. Furthermore, we worked to strengthen the functions ofseismometers alongside railway lines since FY2016. As a result, we now
can issue warnings to trains more quickly than before.

Earthquake-Resistance
Measures

Tsunami countermeasures
JR Central defines the Conventional Line segments that a tsunami is expected to reach as a“tsunami
hazard expected area,” based on the tsunami hazard map of each municipality. When a tsunami
is expected, first of all, we make arrangements to ensure that no trains enter the “tsunami hazard
expected area.”For trains already in the area, we move them out of the area or guide passengers to asafe place. In addition, a“tsunami warning sign”has been installed in the area to indicate the directionof evacuation. We also take measures to evacuate quickly by displaying the evacuation route to thenearest evacuation center on tablet devices for conventional line train drivers distributed to train crews.
Furthermore, to ensure that these measures can be taken, we make sure that staff are aware of themand conduct evacuation training using actual rolling stock in cooperation with local municipalities.

Rain countermeasures
We are taking measures such as protecting the slopes of embankments and cut
sections with concrete and other materials, laying drainage pipes to promote drainage, andinstalling earth and sand stoppers to prevent the inflow of earth and sand. Furthermore,rain gauges are installed along railway lines, and when the amount of rainfall exceeds
the regulation value, a warning is automatically issued to the control center, train station,etc., and operation regulations such as stopping or slowing down trains are carried out.
Furthermore, in June 2020, we introduced an operation regulation using rainfall radars,
which can finely capture“soil rainfall,”a superior indicator for grasping the extent of
sediment disaster risk, and localized heavy downpour, in all sections of Conventional Lines,
thereby securing a higher level of safety.

Operation Management and Safety Measures
Tokaido Shinkansen
The principle of Crash Avoidance

How ATC works

The biggest feature of the Tokaido Shinkansen and other Japanese
high-speed railway systems is the introduction of an operation control
system based on the principle of Crash Avoidance. This principle
has been derived to prevent the possibility of a collision by using (1)dedicated tracks for high speed passenger rail service, which have nograde crossings, and (2) an Automatic Train Control (ATC) system,
which automatically controls the speed limit of high speed trains andprevents collisions from happening.

Measures against landslides
For Conventional Line routes where there is a risk of landslides, we have installed falling rockretaining walls, rock cover works, and avalanche retaining walls as protective equipment. In
addition, if a rock fall or an avalanche is detected by a detector, the train is stopped to prevent
accidents.
Falling rock retaining walls and alarm devices

Snow protection
When snow falls or accumulates, Tokaido Shinkansen trains may operate at a lower speed to preventthe equipment below train floors from being damaged, hit by stones of ballast being lifted up when a massof snow, formed under the train floor by drifts caused by the train’s movement, drops onto the tracks. Asa countermeasure, we use rotary brush vehicles to remove snow before the first trains. In the particularly
snowy Sekigahara section, we have installed sprinklers to moisten snow to prevent drifts from being
lifted up. For N700S, measures on the train side to prevent snow from sticking to train bodies have beenenhanced, such as changing the shape of the bogie cover. Furthermore, we use ground-installed cameras
to monitor the situation of snow sticking to train bogies and ensure trains operate at an appropriate speed.
We have also installed a high-pressure washing machine to quickly remove snow stuck to trains at stations.

to maintain the necessary vehicle inspection functions to ensure the stable operation of trains
against flooding anticipated for railway facilities. In addition, we have plans to evacuate trains in
train-parking areas exposed to the risk of being flooded, and regularly conduct train evacuation
drills to be able to evacuate trains according to such plans if the risk of damage arises.

Oct. 2004 Mid Niigata Prefecture Earthquake

The safe and reliable transportation of the Shinkansen is supported by
the Shinkansen General Control Center in Tokyo, where directors workin close collaboration using various systems, such as Computer Aided
Traffic Control (COMTRAC*), to accurately grasp a significant amount of
information, including the operational status of trains and the utilization
status of facilities, control overall transportation services, and manage theirsafety.
Moreover, the Shinkansen Second General Control Center has been
established in Osaka jointly with JR West, and is equipped with thesame functions as the Shinkansen General Control Center in Tokyo sothat it can serve as an alternative control center should Tokyo’s General
Control Center become non-operational due to a disaster. Thus, we havestrengthened our crisis management in preparation for emergencies.
*COMTRAC (COMputer-aided TRAffic Control): A system that controls train routes,
manages train operations, and operates and manages the allocation of staff (drivers
and conductors) and rolling stock. Based on input data prescribing the operational
conditions for each train (such as station departure and arrival times, platforms, andorder of movement) in the computer, the system can monitor the status of all trains inoperation at all times.

The Shinkansen Multiple Inspection Train (Dr. Yellow)
We have also introduced the“Shinkansen Multiple Inspection Train(Dr. Yellow)”to test electrical facilities such as overhead wires andground facilities such as tracks. This rolling stock, which is based on
the Series 700, aids safe and reliable transportation by efficiently
conducting high precision inspections at speeds of 270 km/h.

Cyber security measures
In terms of systems, we are also working to build a safe and resilient
infrastructure. We are taking necessary measures, including achieving theredundancy of facilities and securing backups, to ensure that the provisionof services to customers and the execution of internal operations will not
be disrupted due to earthquakes and other natural disasters and system
failures. For example, the Shinkansen Operation Management System
has an alternative center in Osaka in case the system center in Tokyo
is damaged, and the Express Reservation System comprises multiple
computers to ensure sufficient processing capacity even if one computer
fails. In addition, we regularly conduct drills to prepare for natural disasters
and system failures.
Furthermore, we have taken all possible measures to ensure systemsecurity against cyber attacks, which have been increasing in recent years.
For example, for systems that require absolute safety, such as thoserelated to train operation, we have established an independent system
structure that eliminates any contact with the outside world, thereby
avoiding external attacks.
