The unprecedented disruption on Yamagata Shinkansen

Yamagata Shinkansen has been operating with significantly reduced services for nearly a month due to train faults. The line has been severely disrupted in summer, and it may have a huge negative impact on local economy.

On 17th June, Tohoku Shinkansen was closed for 5.5 hours due to broken down trains. Initially, it was reported that the newest unit of E8 series came to a halt because of fatal technical failure whilst testing, but according to Nikkei, three more units suffered from similar failure on the same day. According to JR East, a power system on each units that converts power for other devices broke down so that a cooling system stopped, and thus the trains could not reactivate. It was later found that the power system was severely damaged or even partly melted. The cause of the troubles remains unknown.

The E8 series entered into service in March 2024, and eleven seven-carriage units have been introduced as of today. Five of them have been taken out of service and are under investigation. JR East timidly reinstated other units to passenger services, but the company has decided to use the units always with 10-car E5 series trains. They are used only for a handful Yamabiko services between Tokyo and Sendai. In other words, the company has not used the E8 series units independently since then.


As a result, there has been a severe shortage of trains. JR East has been using E3 series trains alongside the E8 series, but the E8 series trains have been unable to engage in passenger services between Fukushima and Shinjo, so all Yamagata Shinkansen services are provided by old E3 series trains. However, the number of the E3 series is not sufficient, as the old trains have been gradually replaced with the E8 series. Hence, Nikkei estimated that the daily capacity would decrease by up to 40%.

JR East had no choice but to cancel almost of all direct services between Tokyo and Yamagata or Shinjo. According to the temporary timetables, E3 series trains run between Fukushima and Shinjo, and all passengers to and from Tokyo or Omiya are required to change trains at Fukushima station. As trains have to wait for the transfer, there have been minor delays on some services.

JR East and manufacturers are struggling to figure out the cause. Hence, JR East announced on Wednesday that the service reduction will continue until at least the end of July. Amidst concerns over local economy, Asahi Shimbun reported that the Governor of Yamagata Prefecture urged JR East to carry out all the necessary investigations and resume the services as soon as possible. In response to her request, JR East decided to provide three direct trains to and from Tokyo from Saturday 19th July using the E3 series, but there will be even fewer services between Fukushima and Shinjo due to lack of available trains. At present, it is highly uncertain if all E8 series will be reinstated before Obon holidays in mid-August, one of the busiest seasons in Japan.

Mojiko, Another Important Cultural Property

Mojiko is a station where Kagoshima Main Line begins. It was once vital for the entire island of Kyushu, but trains running between Kyushu and the Main Island (Honshu) have completely been rerouted. Nevertheless, Mojiko still remains as a symbol of the area, and its historic building is highly popular among tourists.


Mojiko is one of two active stations that are designated by the government as an Important Cultural Property (the other one is Tokyo station). Opened in 1891 as Kyushu Railway's Moji station, it had been the most important railway terminal in Kyushu until 1942, when Kanmon Tunnel connecting Shimonoseki and Moji opened. At the same time, Moji station was renamed Mojiko.


The current building was built in 1914, seven years after the nationalisation of Kyushu Railway. There are many things to see, not only the architecture itself but also interior features such as the ticket hall, ticket office and waiting room. The main building is magnificent especially at night when it is illuminated. While most tourists visit the area during the daytime and leave by sunset, it is worth waiting until it gets dark.


According to the statistics, the annual entry and exit in 2023 was approximately 3.5 million, less than 4% of that of Hakata (the busiest station on JR Kyushu network). Mojiko station is mostly empty except during rush hours, so these platforms look disproportionately long. They remind us of the days when millions of passengers and tonnes of goods a year relied on trains and ferries to cross the Kanmon Straits.


Mojiko is a place where old western-style buildings are preserved. It is a small but lovely tourist spot, and it takes only 15 minutes from Kokura by train. Shimonoseki, another city known for such buildings and fugu (blowfish) dishes, is just five minutes away by boat.

Tokyo station, where two prime ministers were assassinated

Tokyo station is arguably the most famous railway hub in Japan, and is effectively the central station of the capital. The iconic red brick building on the west side, known as Marunouchi Side, was built in 1914. While largely destroyed during the Bombing of Tokyo in 1945, the building was reconstructed two years later, and it was restored to the original style in 2012. Today, it is one of just two active railway stations registered as the Important Cultural Property by the Government.

Tokyo station is generally seen as a symbol of the country's positive aspects, such as westernisation, modernisation and prosperity as well as resilience after the Second World War, but it also represents negative historical memories that are often overlooked. This is the place where two incumbent prime ministers were killed.


On 4th November 1921, Takashi Hara was stabbed to death by an 18-year-old pointsman of the Railway Ministry. There is a small plate on the wall, just next to a ticket machine at "Marunouchi South Entrance/Exit", with a tiny hexagon mark next to a small square pattern on the floor, showing the precise position of the incident.

Takashi Hara was the first commoner to become prime minister in Japanese history. He took office in 1918, and it was the first time in history that a member of the House of Representatives became the prime minister. This is why his premiership is sometimes called the dawn of democracy in Japan. It is also worth noting that he was the only Christian prime minister before the Second World War.

During his premiership, he engaged in improving higher education, including establishment or reorganisation of many private universities (e.g. Waseda, Keio and Doshisha) as well as new "higher schools" (different to high schools of today). However, inflation after the First World War remained stubbornly high, and the cost of living crisis led to criticisms of prioritising business leaders rather than citizens, which are said to have triggered the assassination.


The inscription reads:

On 4th November 1921 at 7:20 pm, Prime Minister Takashi Hara was walking towards a ticket gate at Marunouchi South Entrance to visit Kyoto, where a party conference of Seiyukai's Kyoto branch would be held. Then, a young man ran out and grazed a shoulder of Yoshikazu Takahashi (the first stationmaster) and suddenly stabbed Hara in his right chest with a six-inch dagger. Hara collapsed on the spot and received first aid treatment at the stationmaster's office, but he was already dead. The assailant stated that he committed the murder because he was dissatisfied with Hara and his cabinet's high-handed policies, but the true background of the incident remained unclear.

It was the very first assassination of a sitting prime minister in Japan. The assailant was sentenced to life imprisonment but pardoned in 1934. Since his imprisonment was disproportionately short, there have been rumours or even conspiracy theories about possible connection between him and other ultra right-wing activists, but it has not been verified. He died in 1980 at the age of 77.


Another prime minister was killed in less than ten years. On 14th November 1930, Osachi Hamaguchi was shot by a 21-year-old right-wing activist at the station, and died in the following year. There is another plate on the wall and a tile on the floor near a lift to platforms 9 and 10 at the central concourse, though the square symbol does not represent the actual position of the incident (he was actually shot at the platform above).

Osachi Hamaguchi became prime minister in 1929 and known for being dovish and an internationalist both diplomatically and economically. He also pursued austerity and reduction of armament that infuriated many Japanese. The public rage at him peaked when he ratified the Treaty for the Limitation and Reduction of Naval Armament (also known as the London Naval Treaty), which Hamaguchi believed helpful for both budget cut and maintaining good relationship with the United Kingdom and the United States. He was accused by opposition parties and the military of violating Article 11 of the constitution, which prescribed that "The Emperor has the supreme command of the Army and Navy", while he and ministers believed that approval of the Diet and the Privy Council would suffice.


The inscription reads:

On 14th November 1930 at 8:58 am, Prime Minister Osachi Hamaguchi was walking down the platform to the first-class coach of the Limited Express "Tsubame" that would depart at 9 am, en route to Okayama Prefecture to observe a special army manoeuvre. Then, a gunshot rang out, and Hamaguchi collapsed, clutching his abdomen. He received first aid by doctors, and underwent surgery at the Tokyo Imperial University Hospital. His condition initially seemed to improve, but died on 26th August in the following year. It is said that the assailant committed the attack as he opposed Hamaguchi's government, led by Constitutional Democratic Party, which resisted pressure from the military during the ratification of the London Treaty.

After the assassination of Hara, the authorities decided to temporarily close part of a station when a prime minister was about to board or alight from a train, but Hamaguchi asked the security personnel to lift the restriction as he did not want to inconvenience other citizens. It ended up with the tragedy.

This incident had a significant impact on the Japanese politics. This case and the assassination of Tsuyoshi Inukai, another sitting prime minister killed in 1932, were decisive for the premature democracy in the country, consequently replaced with militarism.

These memorials are very subtle and not noticeable, presumably because they are not something the Japanese people or JR East are proud of. Even so, these marks silently remind us of significant moments in history. As the world is deeply divided with disinformation and agitation, they also remind us that the true value of these monuments should never be underestimated.

The Red List of Trains in Japan (Jun-2025 update)

The Red List of Trains in Japan is now up to date! No new article this time, but many existing articles have got the latest figures. Important changes include:

  • Rolled back the status of JR East 255 series from EXTINCT to CRITICALLY ENDANGERED, as the company decided to retain one for a while despite its farewell tour being conducted last year
  • Changed the status of Isumi Railway 300 and 350 series as the line itself has been "temporarily" closed for years

I stumbled across a master's dissertation from Spain that cited my website. While I am honoured to be seen as such a credible source, I feel a little bit awkward about it. The site was never intended to be academic, so why their supervisor approved the use of an anonymous hobby website?

I also recently discovered that my website has been used for academic purposes. While I am truly grateful for it, I would like to emphasise that this website is just a personal, unofficial one. I always endeavour to provide accurate and up-to-date information as much as possible, but you should always consider very carefully before you cite anything on my website and this blog.

The Tram, another stark reminder from the past

Hiroshima is known for having the most extensive tram network in Japan. Most tourists to here visit the the Peace Memorial Museum and Genbaku Dome (also known as the Atomic Bomb Dome) just like G7 leaders did in 2023. Many people believe that the Dome is the only survivor of the very first nuclear attack in history, but as BBC reported back in 2015, it is not true. This is No. 651 of Hiroshima's tram, one of few vehicles that survived the day.

This is Hiroshima Electric Railway 650 series, a tram type developed in 1942. Five trams were introduced, and all of them were damaged at quarter past eight on 6th August 1945, some of them destroyed. Yet, the company repaired all of them and thus they were all eventually reinstated. All 650 series trams were supposed to be withdrawn by 2006, but the company decided to preserve some of them. Today, three trams are still registered for mainline use, and they are often used as charter trains including school trips for teenagers. In addition, nos. 651 and 652 sometimes run during morning rush hours on weekdays.


No. 651 was about to depart Fukuromachi tram stop towards Senda depot, presumably after being used for a charter train on Saturday afternoon. The grey building on the left is the former Hiroshima Branch of the Bank of Japan, another building that withstood the bomb. Together with modern buildings nearby, they highlight how much the city has developed since then, and how important it is to preserve such heritage to remember that day.

It should be noted that the heritage sites in Hiroshima have been preserved not to emphasise the "atrocities committed by the United States", but rather to serve as a memorial, reminding us that regardless of views on nuclear weapons, they should never be used again under any circumstances. As the 80th anniversary of the end of the Second World War (commonly known outside Japan as the VJ Day) is approaching, and given that the substantial risk of another nuclear attack amidst conflicts including those in Eastern Europe, the Middle East and South Asia, the 650 series trams are not just cute and retro vehicles, but they present us a stark warning.
