Keio Plaza Hotel

Despite being surrounded by fantastic hole-in-the-wall spots and high-end eateries, the hotel has nearly two dozen restaurants to choose from. Tuck into something authentically Japanese, venture a little further afield, or opt for something with the utmost convenience at the hotel's 24/7 international buffet. There's also a great selection of waterholes including a sake bar and the 45th-floor cocktail bar – the views are utterly incredible. On the rooftop terrace, there is a seasonal outdoor pool and a few floors down, you'll find the Carju Rajah Tiado spa.

This hotel is, in a word, mega. It has over 1,400 rooms, ranging from simple and cosy to all-out luxury. With interiors done by GA Design, a high-end British firm with a number of fabulous hotel under their belt, your comfort is guaranteed. All come with a king, queen or twin Sealy beds, fully-stocked minibar and air purifier. The bathrooms are beautifully-done with jasmine and bergamot toiletries by L'Occitane and Imabari towels. The suites are, of course, found on the higher floors and enjoy a sitting and dining area.

Being in such close proximity to a station, Japan is your oyster from the Keio Plaza. Venture out to explore the Shinjuku Skyscraper District, visit the stunning Shinjuku Gyoen National Garden or get lost amongst the Golden Gai bars. There is also a bevy of day trips including escapes into nature, historic towns or a little interlude at the beach. At the hotel itself, enjoy a traditional tea ceremony or try your hand at ikebana flower arranging.
