answer:1. Learn a bit Japanese. Not many Japanese can speak English. If you like, I will show you some basic Japanese (for greeting, since Japanese expect people to greet each other often): – おはぞうございます (o-ha-zo-go-zai-ma-s): good morning – こんにちは (kon-ni-chi-wa): hello, good afternoon – こんばんは (kon-ban-wa): good evening – さようなら (sa-yo-na-ra): good night – おげんきですか?(o-gen-ki-de-su-ka): how are you? – はい、げんきです (hai, gen-ki-de-s): yes, I’m fine. – ありがとうございます (a-ri-ga-to-go-zai-ma-s): thank you very much – どういたしまして(do-i-ta-shi-ma-shi-te): you are welcome – いらっしゃいませ (i-ras-sai-ma-se): (not very sure about this one but it generally means “welcome” and spoken by shopkeeper/waiter…) 2. Learn a bit about Japanese manners. They’ve got a long list of manners so steer yourself. 3. Pay with the yen currency in most circumstances! I heard that except in some international places, Japanese don’t accept any currency apart from yen. 4. (Optional) If you can, learn a bit Japanese “alphabets”, namely the hiragana and katakana. Some Japanese words are taken from English and knowledge of katakana can help you guess the meanings of words. Those are some tips for interaction with Japanese. Not sure about must see/ must do activities though…
