About

Designed by renowned architect Kengo Kuma, ONE@Tokyo is a striking industrial-chic hotel that beautifully fuses raw concrete and warm wood elements. Located in Sumida, it features a spectacular rooftop terrace offering unobstructed, up-close views of the Tokyo Skytree. Expect minimalist, thoughtfully designed rooms and a stylish lobby cafe that serves as a creative hub for modern travelers.

What Japanese guides note

Japanese sources emphasize using Exit B3 when arriving via Oshiage Station with wheeled luggage, as it is fitted with escalators, while the closer Exit A1 has only stairways and is shuttered overnight. The hotel is situated inside a quiet residential neighborhood just east of Tokyo Skytree Town, keeping street noise minimal despite the heavy foot traffic around the station. Guests planning evening visits to the open-air rooftop deck should keep in mind that it closes promptly at 22:00 to comply with local residential quiet hours.
