Tetsuko no Tabi - MAL Score - 6,35 by 367 Users
This anime is both unpopular and under appreciated. I am not too surprised at this because it is a niche series. I personally enjoyed it precisely because it is something rather unique. What is unique about it you might ask? Well that is probably the fact that is a series all about the JR, the Japanese railway system.
The story is about an author that gets tricked into writing a manga about travelling but unbeknownst to her it is quite literally about travelling, and accompanying her is the travel writer/ tetsuko (railway otaku.) So the series is literally about how she, her editor and the travel writer go around Japan using the widespread JR system. It does not focus on the place they visit but the train stations since they hop from one train to another since their aim is to visit train stations and experience travelling in the JR system.
It is series with a particular focus that obviously means it is not for everyone, in that sense it is a niche series. This niche-ness shows itself in its lack of popularity in all anime sites like MAL and the likes. It is also rather lowly rated in such sites. It is not masterpiece but I feel like it is a refreshing series that can be rather peaceful and also show people a bit of the nature of Japan and its well developed transport system.
It is not a technically impressive series either and the character designs are not great either. But it does have beautiful scenery and soothing music, so it is a great relaxing series that is probably not seen by many people because of its initial image and setting.
