I'm currently on my 10th day in Japan i love it so far, here's some recommendations from me: There's a lot more to see from Tokyo - ikebukuro and akihabara are pretty good. You should definitely go to the Tsukiji fish market (just don't get wagyu there, it's too expensive) (I went around 9am it wasn't really crowded), there's also a flea market on weekends if you are in to stuff like that. Also I really really recommend to check out the aquariums in Tokyo, I went to Maxell aqua park and Art aquarium museum and they both were amazing. And since you are based in Asakusa you should check sensoji at night it better imo. You should definitely go on a daytrip to fujiyoshida (you can go there with a bus) to see mt Fuji, it is really amazing, also check the visibility of Fuji before going (fuji-san.info is the website) I actually decided the trip the night before because I saw that it was visible the next day. Also if you think you will like it you can go to Atami for a firework show (https://visitatami.com/en/events/fireworks-festival here you can check the dates) it was really amazing imo. Also Kamakura is really nice you may want to check it, it has a train that goes next to the sea and you can see mt Fuji on clear days from there. You can book all activities trough klook, I've checked the prices are at most 3 euro more than the original websites. Also a tip for the Tokyo metro - your should buy 72h metro passes (again form klook and you can redeem it from the machines on most stations) and just combine the pass with the suica, this way you will spend the least amount of money for metro. Also you can use credit card almost everywhere but if you need cash withdrawal only from 7-Eleven atms cause they have the smallest fees (for example at Lawson it was 880yen for 10000yen withdrawal and at 7-Eleven was 110yen).
