Dear John,
I am coco(,) Anne’s cousin. I come from Taiwan and I can speak English and Japanese. When I (spoke) to Anne, I planned (for her) to travel to Japan. She recommended me to contact you because you are living in Tokyo. ~you can keep the now if you would like it still fits just sounds more professional this way~ :) 

Do you mind (giving) me suggestion? I plan to stay in Tokyo for 5 days. Do you know which hotel will (economically benefit me) and (is also) safe? I googled ~i don't think googled is a actual word in the dictionary if i'm honest but people WILL understand it better~ some people slept in (a) capsule hotel and the price is very cheap (compared to) others. (What) do you think? (Would) you recommend it?

I researched some of famous scenes in Tokyo and I have made a travel list. Could you review my attachment? Is it possible to finish all the tourist spots in 5 days? I know it will become very (rushed), (especially) if I want to buy some souvenirs on my trip. Could you organize my schedule or give me some local traffic information. (is there) UBER in Tokyo? Can I use it (is it) legal?

(and lastly), do you need (some) stuff from Taiwan that I can bring (for) you? I will arrive on April the 10th the morning and leave on the April 15 after lunch. We can meet if you are available. Anne has a gift (for) you.

I (am) looking forward to hear from you.

Sincerely

Coco
