After landing at Haneda Airport around 5am and finding I couldn’t exchange my JR Pass at the airport until close to 8, I decided to see if I’d have better luck at Shinagawa station, but alas it was not to be (they open at 9am), so I headed to Tokyo station where I knew the ticket office started exchanging JR Passes at 7:30am. I was 2nd in the queue and I had my JR Pass and a reserved seat on the Shinkansen to Nagoya in my hands by 7:45. A quick snack at Tokyo station and I was on my way to Nagoya at 200km/h around 8:30am.
I arrived in Nagoya station around 10:20am. The ANA Crowne Plaza Hotel Grand Court Nagoya is in the Kanayama area of Nagoya right next to Kanayama station. You can get there using your JR Pass for the ~5 minute train trip.
