If you’re moving around Tokyo, trains are overwhelmingly more convenient than cars. It’s a good idea to take a taxi when you have heavy luggage, but be aware that Tokyo has a lot of traffic, and it can take more time than you expect. Japanese trains are punctual, efficient in coordination, and allow you to access anywhere in a short amount of time. Riding trains in a foreign country may seem daunting, but most of them have English signage and announcements.
I don’t recommend traveling by bus. Even for Japanese people, understanding bus routes can be difficult, and payment methods vary by bus company, which can be confusing.
When you arrive at Tokyo Station or Shinjuku Station, you might be overwhelmed by the sheer number of trains and people. In such cases, don’t hesitate to ask the local Japanese people for help. They will kindly advise you until you understand and may even guide you to the train you should take. Japanese people enjoy helping distressed foreign travelers, so feel free to approach them. Of course, Google Maps is also a great ally.
By making good use of trains, you’ll feel more at home in Tokyo. If walking is challenging, it can’t be helped for elderly individuals. However, if you want to become an advanced Tokyo explorer, master the trains. If you have extra time, it can be interesting to randomly get off at stations not listed in guidebooks. Most places in Japan are not dangerous. Trying out local eateries that only locals visit can also be a unique way to enjoy your journey. I hope you have fun experiencing multiple small adventures.
