Little Dancer

Little Dancer is a brand of low-floor tram developed by Alna, a manufacturer whose parent company is Hankyu. Trams in Japan are generally known for being old simply because tram business is not profitable, but Little Dancer trams are new, as they have been manufactured since 2001. The brand is popular across the country, as 11 out of 19 tram and light rail operators in Japan have used at least one.


The first Little Dancer, also the very first low-floor tram made in Japan, is Kagoshima Tram 1000 series. People in Kagoshima heavily use the tram network when they go to the city centre, but older trams are small and have a large gap between a tram stop and train floor, which is hard for elderly passengers. The introduction of Little Dancer made them easier to use the tram services, and even wheelchair users are now able to get on and off (except five out of 37 stops due to extremely narrow platforms). Other tram operators in the country followed Kagoshima city.


Some Little Dancer trams in the early days were not always successful because there were still steps inside a tram and thus not fully accessible, and capacity was small so that fewer passengers than older trams could be transported. For example, Iyotetsu 2100 series has been notorious for having very small standing space. As the technology advances, newer types introduced after the late-2000s have been dramatically improved.


Little Dancer is also known for its unique name. The Japanese word "dansa", which is pronounced very similarly to "dancer", means "step". The brand stemmed from a dad joke, as Litttle Dancer also means "little step(s)". It is not surprising given that the manufacturer locates near Osaka, where people thereof have been known for having a great sense of humour.

Nakano Depot Disease

Chuo and Sobu Lines (Local) in Tokyo have been frequently disrupted by sudden drivers' illnesses for nearly four years. Several investigations have been conducted, but the cause remains unknown. In spite of safety prayers by a Shinto clergy, there is no sign of improvement. The so-called "Nakano depot disease" has had negative impacts both on passengers and train crews.


The Chuo and Sobu Lines (Local) is a commuter railway in Tokyo that consists of two lines, Chuo Main Line and Sobu Main Line. They connect Chiba and Mitaka stations, calling at all stations including small ones. They are 60.2 km (37.4 miles) long, and trains formed of ten coaches run every two minutes at peak times.

Tokyo Shimbunreported in 2024 that there have been 40 train disruptions in the past three years as drivers suddenly feeling unwell. Drivers in their 20s to 40s suffered from dizziness, anaemia, drowsiness and stomach aches, resulting in overshooting platforms or partial service suspension lasting 20 to 30 minutes. All of them had no trouble during a daily health check before getting onto a train. There are less than three such cases a year on other lines, but the Chuo and Sobu Lines (Local) apparently have had far more troubles than others.

According to Nippon Cultural Broadcasting, trade unions insisted that the issue were triggered by overworking, but JR East dismissed the claim as no such troubles had been observed on other busy lines such as Yamanote Line. The train operator conducted various investigations including air and water testing at Nakano depot, where drivers and crews gather every day, but no abnormality has been observed. The company even relied on religion, asking a Shinto clergy (kannushi) to pray for safety as well as health, but the situation remains unchanged, as Asahi Shimbun reported.

The government acknowledged the "Nakano depot disease" in response to an enquiry submitted last month by an MP. However, the Ministry of Land, Infrastructure, Transport and Tourism has refused to intervene in the cases at the moment, insisting that JR East should take responsibilities for its employees.


The unreliability of the Chuo and Sobu Lines (Local) is certainly a matter of concern. Trade unions have urged JR East to significantly improve the tight work shifts and replace old facilities with new ones, and the company has accepted some of their demands, but the problem is yet to be solved. Unless the troubles subside, there might be calls for the government to take action. However, it is hard to imagine what measures could the authorities adopt in addition to what the train operator has already done.

When "Shin-Keisei" becomes "Keisei"

Shin-Keisei Electric Railway will be dissolved and merged with Keisei on 1 April 2025. The companies have announced that Shin-Keisei line, connecting Matsudo and Tsudanuma stations in Chiba Prefecture, will be renamed Keisei Matsudo line on the same day. This article summarises relevant documents published by those two companies and describe what will happen in less than less than three months.


The Shin-Keisei line opened in 1947, reusing facilities of the Railway and Shipping Section of the Imperial Japanese Army. Since the line was initially constructed as part of a military exercise, the route is winding. In fact, the railway is 26.5 km (16.5 miles) long while it is less than 16 km (10 miles) as the crow flies. The entire train journey takes 42 minutes while driving a car takes around 30 minutes (even without using a motorway, but when there is no heavy traffic jam). As the name suggests, Shin-Keisei has been part of the Keisei group for decades though Shin-Keisei had not been Keisei's subsidiary until 2022.

According to a document, Keisei's board of directors officially decided in October 2023 to take Shin-Keisei and relevant subsidiaries over to make their businesses more efficient, and it was approved by the authorities in June 2024.


Passengers are likely to find a few changes. As mentioned above, the railway will be rebranded. Station numbers will be changed from SL01 (Matsudo) - SL24 (Keisei-Tsudanuma) to KS66 (Shin-Tsudanuma) - KS88 (Matsudo). Note that not only will alphabets be changed but also the order of the number will be reversed.

Timetables will be mostly unchanged including through-services to and from Keisei Chiba line. Fares will also remain unchanged, meaning that those using both Shin-Keisei and Keisei lines at the same time might feel it expensive (as always).


The other good news is that trains will gradually be repainted red and blue like other Keisei trains. Shin-Keisei has been notorious for painting its trains obnoxiously vivid, but probably a few daily users will one day miss the pink trains.

New Year Greetings 2025

The year 2025 has begun. I wish all of you lots of luck and happiness. As the new year began, I would like to write a few things about this blog, my website and social media accounts.


About this blog

I keep posting a new article every other week as I did last year. A new article will be uploaded on the second and fourth Saturdays every month. However, it might be difficult to do so later this year as I get busier, in which case I will notify everyone on social media platforms listed further below.


About the website

The Red List of Trains in Japan will be updated every 3-4 months. There is no plan of adding lots of new articles, but I will keep them up to date as much as possible.


About social media

As I have reiterated last year (including the "resolution" on 1 October 2024), I have got ridden of X (former Twitter) and all accounts have now been terminated. I use three social media platforms as follows:

"x years ago today", a series of posts with a train photo I upload at 8:30 pm every Thursday (Japan Time), will be available on these three platforms. I also welcome any questions or replies related to railways in Japan or any other topics.
