First the basics... my ratings are based on comparing this hotel to others in the same high caliber. This is a typical high quality Intercontinental Hotel. The staff is super professional and polite, the rooms are impeccable.

What makes this hotel strategic AND fun is its location in Tokyo. LOCATION, LOCATION, LOCATION is a critical decision when traveling to Tokyo.

This hotel is right on the water and out of the way of the hustle and bustle of the city. It is also a great location if you have business both in Tokyo and Yokohama. When I travel to Tokyo I plan my hotel stays based on where I have to go. You can waste a LOT of time in Tokyo-Yokohama just traveling on the subways and trains. Make this a critical selection factor when deciding where to stay in Tokyo.
It´s a ten minute walk from the Hamamatsucho Japan Rail station. If you have to go to the Ginza area, just take the Yurikamome elevated train from Takeshiba station which you can reach without even going down to the street level. There's a path straight from the hotel to the station. SUPER convenient!
Another important factor... you can take the monorail to/from Hamamatsucho from/to Haneda. From now on, I will try my best to take trans-Pacific flights into Haneda. It is SO much more convenient than traveling via Narita.
However, if you have to travel via Narita, then take the train from Narita to Shimbashi station and then the Yurikamome to the hotel (Takeshiba station). You can also take the Orange Limousine buses to the hotel, however, here´s the catch... this is the last hotel on the bus route from Narita, and the first on the way to Narita, therefore you´ll have a long ride within the city before you get to the hotel.
I will return to this hotel and would recommend to a friend if it makes sense from a location perspective.

We checked in at the Intercontinental Hotel Tokyo Bay, right from check in, it was a wonderful
experience, the staff were very polite, always willing to help, they had transport available from
early morning until late at night, to and from the subway station,but the only major problem
was the internet,thier charges were exceptionally high,whereas the Ana crowne plaza in Osaka had free wifi, really super fast. We did not eat in any of the restaurants,as we use to leave early,and come back late on the last Bus, they did have free internet access at the
business centre, they had two desktops there which were really outdated and one of the two was out of service.All in all it was a good stay, and we took the bus service forr 3000 yen straight to the airport.

This hotel is located very close to 3 train stations making access to the whole of tokyo very easy. The quality of the rooms is exceptional as you would expect with a 5* japanese hotel.
The breakfast is quite good although very expensive for what it is.
WiFi and Internet is charged which is quite unbelievable for today.
There are many services supplied, you can get the bus direct to the airport from the hotel for 3000 yen.
Overall a nice stay but quite expensive.

This was my second stay at the Intercontinental Tokyo Bay, and although the hotel is still a good standard I do feel that overall the hotel standards are slipping.
My greatest concern would be the quality of the service in the restaurants. I feel both the service and quality of the food was not good enough either for Lunch (which I tried once and walked out) and Dinner which again was poor compared to other Intercontinental's I have used.
The rooms are beginning to look tired also, though impeccably clean as you would expect. The gym was constantly closed for "private sessions" though looking through the window it looked a good standard wish I could have got to use it.
For the cost of this hotel, which is not cheap by any standards I was left feeling disappointed, the first time ever in a Intercontinental Hotel.
