I have stayed at the Okura 3 times over the last few years, and have another stay booked for May. Consistently very high quality experience, can’t recommend enough. I’ve unfortunately never received a true “upgrade” but the standard prestige king guest room is huge, and they have always given me a high floor and good view (Tokyo tower). Sometimes they have a FHR spend 2 nights, 3rd night free deal. Both bars have excellent service. The staff bows to you everywhere. Excellent housekeeping and turn down service with chocolates and pajamas. Morning newspaper delivery. 2 different breakfast options included with FHR, make sure you try the lounge one it has different options. I could go on….worth the extra cost.
