Firstly. Impressive reception area. Looks 5 star but rooms don’t match. The rooms are large but out - dated. Internet is the worst we have had in all our Japanese hotels .
Be aware!!!This is a very busy hotel over 400 guests...so be prepared to wait and queue for breakfast and reception services.
You are NOT in the city of Tokyo so the subway pass doesn’t work. On the monorail. We spent an extra £50 over 5 days on the monorail , which you get from Shimbashi.
The ride into Tokyo central takes a Good 15 mins Tokyo good 40 minutes , if you understand the underground.
Can I give a mention to the lady concierge who really did an excellent job organising a restaurant reservation for me and my son. She organised a cake for his birthday . The restaurant did this and provided a photo for us to remember. This was exceptional. We had a great view from the Sky Tree Tower.
Thank you so much you made our stay memorable.
Ok, now the bad points.:
The staff have very limited English.
They couldn’t even say. Please wait on the 30 floor bar while your room is prepared. ... we arrived 45 minutes before check in.
However the brilliant lady in the concierge came to the rescue. She really is exceptional.

I say this as some who worked in the travel industry internationally, Hawaii, Brazil, USA, Singapore Uk, Spain and Italy for 6 years for Thomson Holidays. I know what good customer service should be.
I don’t know if it’s a cultural thing but the Japanese are not flexible like other nations. You really can’t do this. You will have the Olympics next year. Not all nationals have “ follow the rules “ do as I say attitude “. This comes across as rude to Europeans and Western nations. Again holding you hand up in my face is offensive in Western culture. I know somethings are cultural. But remember about 40% of your business is probably from the West.
All in all the hotel is in a privileged spot with a fantastic view of Tokyo bay. We enjoyed our stay.
I wouldn’t use this hotel again as it’s so far out.

Super hotel at Odaiba!
Great service and very good quality.
There is a limousine bus from Haneda Airport. It stops directly at this hotel.
The rooms are spacious with a beautiful view on Odaiba.
There are some restaurants, but a little bit expensive. But no worries, at 5 min by walk, there is a big shopping mall with numerous restaurants.

Daiba station in at 1 minutes from hotel.

This hotel offers a free shuttle to go to Disneyland Tokyo.

Grand Nikko Tokyo is a very big hotel...much bigger than the normal Tokyo hotels. The rooms are very spacious and we had 4 big single beds in the room. The bathrooms are quite big with tub and shower. the rooms are really nice and comfortable and the staff speaks English. The staff is very courteous and helpful. The hotel is little far from the city centre but is connected via bus which goes from right outside the hotel as well as train. The station is connected to the hotel. Easy to travel to the hotel and the city centre. There are two big malls next to the hotel. Hotel is situated on the bay and views are awesome. there is a statue of liberty nearby and rainbow bridge which are the sights to see in Tokyo.
Would recommend this hotel in case travelling to Tokyo for pleasure.
