The legendary designer Isamu Kenmochi took on the role of overall director for the interior design of Keio Plaza Hotel, aiming to create a “Japanese hotel that the world can be proud of.” At the time, in 1971, most hotels had a classical design, but Keio Plaza Hotel’s modern interior design, which appealed to the five senses, quickly became a hot topic.
To achieve a diverse and enjoyable design, Kenmochi hired many talented young artists and designers. The interior of the hotel was like a museum filled with relaxation and elegance. The chief engineer in charge of the interior design under Kenmochi’s direction said, “We chose freshness, crispness, and fun as the expression of this skyscraper hotel. (Omitted) We wanted to create a hotel that would give guests a sense of excitement and anticipation from the moment they arrived.”
The vibrant colors, bold composition, first-class artwork, fusion of Western and Japanese traditional beauty, and the greenery of the outdoor space all contributed to an interior that was filled with fun and excitement from the moment guests arrived. Even today, the interior is still innovative and attractive.
While some of the interior has been updated over time, the design philosophy remains intact. From the lobby lounge to the restaurants and guest rooms, the hotel has created a space filled with art and playful elements for guests to relax and enjoy. Keio Plaza Hotel’s interior design is warm and inviting, rather than overly luxurious or intimidating.
This design philosophy is still alive and well at Keio Plaza Hotel.
