Can I manage to go to Tokyo from Nagoya?

Hello! I have a trip to Nagoya from sept 14-17. I have friends in Tokyo and they expect me to come. Do you think I can manage it? I know there is shinkansen, but I'm afraid I might get lost. I have one luggage. Will I bring it along with me inside the train. Also my flight is a roundtrip ticket from MNL to NGO. That means, I have to go back to Nagoya from Tokyo. Isn't going to be taxing? I have a project with Waseda University so I really want to go there. How long and how do I get to Waseda from Tokyo. I hope I could be led to someone or a website for help. I'm excited to visit Japan.Thank you very much.

Is your flight leaving the 17th or 18th?

What time do you arrive the 14th?

Also what time is your flight leaving on the 17th (or 18th)

I'm not sure how you are counting your days, if you are arriving on the 13th and have the 14th free or arriving on the 14th and leaving (vice versa for the 17th).

Thanks, John. I'm leaving for Nagoya on the 14th and will be back to Manila on the 19th. The conference is on Sept 15-17. I'm alloting the 18th for the Tokyo and Waseda University visit.

also, if I take Northwest, I'll arrive on the 14th at 1145. My flight from Nagoya to Manila on the 19th will be at 750pm. Thanks
