I stayed 5 days at this hotel while attending a Government of Japan hosted meeting. The corner room on an upper floor of the tower building was as large as any 4 or 5 star hotel room I have stayed in and well furnished. The bathroom was excellent in quality and size as well as with the toilet articles supplied. It is a huge rambling main floor conecting three buildings. The main lobby and other areas a little dated in their furnishings but clean and high quality. Although there are something like 35 or 37 bars and restaurants, they are pricy, especially the branch of the famous Paris restuarant located on the main floor ($400 easily for the menu without any drinks). The sandwich luncheon buffet overlooking the lovely Japanese garden is worth enjoying but be early as there is a rush and the food starts to run out. Likewise highly recommended is a tea house in the garden and another sushi-type little restaurant hidden in centre of the garden. The breakfast on the 40th floor at $35 is not worth that price except for the view of Mount Fuji which was perhaps worth the price. There is a Starbucks in the lower shopping level which is fine. The staff were very polite and the young lady who took my bags to my room insisted that I not tip which was refreshing.

I was traveling on business and just checked out of the Grand Hyatt. Since it was going to be on my dime, I decided to stay somewhere more affordable. I was pampered and completely spoiled with luxury at the Grand Hyatt...so it's not fair to compare. The staff like any 4 star hotel in Tokyo were warm and accomodating. Everyone smiles and tries to be helpful...I wish all 4 star hotels all over the world share that same enthusiam. The room was a good size for Tokyo, but the bathroom was small in comparison. It didn't have any of the fancy amenities that I experienced at the Grand Hyatt, but hey...it's cheaper. The only positive regarding the location was that the nearest subway station seem to connect with every well known tourist area. All in all, even though it was cheaper, for the price I ended up paying, I expected a bit more.

We were only in Tokyo for a day but got a lot out our time by staying in the New Otani. The staff was very hospitable, the gardens were beautiful as well as the view from our room. We stayed in one of the rooms that had not been renovated and was outdated compared to the rest of the hotel. On the other hand, the Otani is in a great location for restaurants and shopping.

We have stayed in August at the New Otani and it was a wonderful experience. Become a member through the hotel´s website to avoid the long check in lines. Because of this card not only did we avoid the long lines, but also had private check in and upgrade to a just recently renovated room with beautiful decoration, flat screet tv and excellent bath amenities and cosmetics. Customer service and concierge are excellent, but do take the leaflets from their desk as there are activities and attractions not mentioned by them.
This hotel is considered to be one of the top 5 in Japan, but make sure you get a room in the renovated part of the hotel. IT consists of different buildings, more than 35 restaurants, many lounge bars. Be sure to visit the lounge bar on the top floor where you can have a magnificent Tokyo view by night listening to jazz music (reminded me of New York).
The restaurants in the hotel are not the quality you would expect in a hotel of this range but there is a street just accross the hotel with many restaurants, cafes, fast food chains, cigar bar. Also, in the Garden Court (business section of the hotel) there is Tully's coffee (a japanese version of starbucks). There is e number of spas and brand name shops (Armani etc).
One of the most beautiful places of the hotel is the 14th ancient garden with traditional plants, lakes, and buildings.
