Life Where I’m From has a video of which he shot an entire day about travelling in trains in Tokyo (albeit, at times, he wandered to neighboring Kanagawa prefecture). I first watched this years before settling down in Greater Tokyo, but I can’t help but felt amazed about the convenience of the public transport in the Tokyo metropolitan area.
The train (and subway) networks are powered by JR East and other private railway companies (Toei, Keikyu, Tokyo Monorail, Keisei, etc.), making not only travelling around places in Tokyo and the neighboring prefectures easy, but also making travelling ahead of time almost unnecessary due to the frequency of trains per hour, where you can plan and travel in minutes interval. Try that with KTM Berhad‘s commuter (spoiler: almost impossible).
When I first settled down in a city located half an hour away from Shinjuku, I planned to jump on each station on every train line in Tokyo every weekend. The starting point of the train station hopping plan was Seibu Shinjuku‘s Hana-Koganei station. Although that plan didn’t get realized while I was living in Tokyo (of which I moved out to Chiba prefecture a few months later), it gradually happened in the summer of 2018. Tokyo metropolitan alone has a lot of train lines and train stations, and it’s impossible to visit every station without spending a lot of time (and money)!
Nevertheless, it is a lot of fun when one travels in Tokyo, especially when you live in Tokyo or are a tourist who likes to roam around. Hop on a random train line. Stop at a random train station. “Tap” out and explore the area, get lost. Fill up your stomach with a bowl of ramen or tonkatsu.
Just recently, I explored the Tokyo Sakura Tram (known also as Toden Arakawa Line) with a one-day pass, and spent half a day exploring the smaller areas in parts of Tokyo (the parts you don’t usually see if one travels by the normal trains). I might write about it someday.
