Confirmed reservation
Hotel dates are all good
Kanazawa was just a typo in the original itinerary. The confirmed KOKO HOTEL Premier Kanazawa Korinbo reservation is Wednesday, March 31 to Friday, April 2 (check-in from 3 PM, checkout before 11 AM). That lines up perfectly with Takayama checkout March 31 and the return to Tokyo April 2.
Most tightly scheduled
Monday, March 29
Tokyo β Nagoya β railway museum β Nagoya β Takayama is doable, but the museum is an additional ~25-minute train ride each way from Nagoya Station. I'd prioritize the earlier afternoon Hida train and avoid treating this like a leisurely museum day.
Book when available
Final Fantasy exhibition
The 40th anniversary exhibition runs through April 4 at Tokyo National Museum. It requires a date-specific morning or afternoon ticket. Friday, April 2 after arriving might be best if the train timing works; otherwise Saturday, April 3. Official exhibition details.
Keep flexible
Baseball versus cat day
The 2027 league schedule has Giants vs. Dragons on Sunday, March 28. That's probably our best baseball option, with Yanaka/Nezu as the excellent no-baseball alternative. We can decide once game tickets and start times are clearer.
