I stayed at the Hyatt Regency Tokyo for two nights in 2014, and again for two nights in January 2015, as part of my Around the World in Eight Days trip. I know there are other Hyatt hotels in Tokyo, and people are rather passionate about them, and downplay the Hyatt Regency, but it actually is a great hotel and a great deal at a category 3 hotel. In each instance, my room was lovely. It wasn’t a suite, but I’m sure it was an upgrade. The view from the window included the Tokyo Metropolitan Government Building, Central Park and, in the distance, the Park Hyatt. Here are some photos.
Plus, the hotel has a very nice Regency Club serving both breakfast in the morning and appetizers and cocktails in the early evening. Indeed, for someone traveling alone with jet lag, the Regency Club was more-or-less my evening activity before collapsing. Did I mention that you could see Mt. Fuji from the Regency Club?
One of the worst club lounge in the system, let alone internationally (which tends to be better than in US.)
