What is the situation of using English to travel independently in Japan?

Reliable. In October last year, as a little follower, I went to Japan for nine days with @shirinli, and it was basically trouble-free. Our situation is: a group of three people, two illiterate people and one illiterate person without 3G network. One of them (shirinli) can pronounce hiragana and has been to Tokyo once before but always took the wrong route. I survived the whole journey by relying on google map tabelog in English. In fact, having 3G network is more important than anything else. The only time someone got lost was the illiterate person who didn't have 3G. It seems that I can't modify it on my mobile phone... I posted half of the answer and then I was so sad that I couldn't modify it... I finally got home and continued writing. We spent about 7 days in Tokyo and about 2 days in Ito. The things I did included: solving problems on the subway and walking, eating all kinds of delicious food (the main purpose of this trip), changing four B&Bs and hotels during the period, taking the not-so-super Yueko to Izu, and riding a bicycle on the Ito beach. Participated in the Ito local festival Hanagasa Yui, wandered into a coffee shop owned by a couple who had returned from England on the Kinosaki coast, waited for the bus at the urban-rural fringe of Izu Plateau in the dark night, and got the last group of visitors to the Tokyo Metropolitan Government Office in the middle of the night. Watch the night view from the scenic level, take a Tokyo cruise from Azuma Bridge to Odaiba, visit the Mitaka Forest Museum of Art, the Aquarium under the Sky Tree and the Fujiko Fujio 80th Exhibition in Tokyo Tower, and shop in Ameyokocho, Ginza and Akihabara. , made a phone reservation at a clinic, ate sushi in Tsukiji, visited Shinjuku Gyoen National Garden and couldn’t enter Meiji Jingu Shrine because of the wrong closing time, was fooled into being fooled into going to Niju Bridge and saw nothing, and was in a store where the clerk didn’t understand English at all. We ate Wagyu beef barbecue in a restaurant, ate ramen in a shop where the chef didn’t understand English at all, stamped the seals at temples in Asakusa and Kamakura, took pictures in front of Shohoku University, kidnapped kittens in Enoshima, and met two people from San Francisco Drinking at an izakaya opened by a gay owner who only speaks Japanese and French after returning from China, etc...
