Nice to meet you too!

That use to be the case, but now (especially since the Olympics are coming up in 2020) in Tokyo and other large cities like Osaka and Nagoya all signs have roman characters as well as the kanji. They've done the same thing in subway and train stations. If you have a smartphone Google Maps is a must for here. It will give you all the train information with times and fares. The only place you won't find English is out in the countryside. Small towns if they aren't big tourist destinations won't have any English. I wouldn't worry though. Any place you would want to go (especially on your first visit here) will have English everywhere including most restaurants. If not, use the Google Translate and have it to the AR/realtime translation via the camera on menus and you can get an idea of what everything is. It works surprisingly well.
