Aman's social sister brand, opened 2024 in Azabudai Hills with 122 rooms by Jean-Michel Gathy, eight restaurants and bars, and a 4,000-square-metre four-floor wellness centre. The most ambitious Tokyo opening of the decade.
"Aman's social sister brand. Where Aman is reverent silence, Janu is open conversation. Eight restaurants, a four-floor wellness centre with a 25-metre pool, and a 30-year urban regeneration district outside the door."
Janu Tokyo opened on 13 March 2024, the world's first hotel from Janu, the new social-luxury sister brand to Aman. The name means "soul" in Sanskrit, and the brand thesis is the inverse of Aman: where Aman is reverent silence and remote retreats, Janu is open conversation and the urban heart of a city. Tokyo was the choice for the launch deliberately, Aman has had a Tokyo presence since 2014, and the brand wanted Janu to debut as a counterpoint, not a substitute. The location is Azabudai Hills, the new Mori-Building-developed urban district that opened progressively from late 2023, anchoring 80,000 square metres of green space, museums, retail, and the supertall Mori JP Tower.
There are 122 rooms and suites, 13 of them suites, designed by Jean-Michel Gathy of the Malaysian studio Denniston, the architect behind the Aman Venice and Cheval Blanc Maldives. The Janu palette is warmer and more textural than Aman: woven rattan, brushed teak, woolen rugs in mist-blue and sand. Deluxe rooms start at 55 square metres, among the largest entry-level keys in Tokyo, with floor-to-ceiling windows facing Tokyo Tower, the Mori JP Tower, or the Azabudai Hills inner park. The 284-square-metre Janu Suite, on the 13th floor, has a private balcony with direct Tokyo Tower views and is the most photographed Janu key in the world.
There are eight dining and entertainment spaces, the most of any new Tokyo five-star opening since 2007. Janu Mediterranean, Iigura by Janu (Japanese), Sumi by Janu (yakitori-and-cocktail), Hu Jing (Cantonese), Bar Gin (the lobby bar), Janu Patisserie, and a private members' wine cellar. The wellness centre, on four levels totalling 4,000 square metres, includes a 25-metre indoor pool, dedicated movement studios for yoga and pilates, two thermal hot pools, a hammam, twelve treatment rooms, and a half-court basketball studio for guided fitness sessions, the most ambitious urban hotel wellness offer in Asia.
Service is the most informal of any Tokyo five-star, no front desk, no formal check-in, a single host meets you at the lift and remains your point of contact. The Azabudai Hills location is the operational headquarters of new Tokyo: TeamLab Borderless reopens in the same complex, the new Mori Digital Art Museum is across the courtyard, and Tokyo Tower is a five-minute walk. Janu Tokyo entered The World's 50 Best Hotels list at number 16 in its first eligible year, the most successful debut in the list's history.
For a serious urban wellness stay in Tokyo, Janu is the answer Aman doesn't quite provide. The four-floor wellness centre at 4,000 square metres dwarfs every Tokyo competitor. Janu's wellness programme runs three- to seven-night stays built around movement (yoga, pilates, the dedicated half-court for HIIT), recovery (hammam, hot-cold contrast plunges), and bodywork (Watsu, Thai-style stretch therapy, sound healing). The TeamLab Borderless museum next door makes for a genuinely meditative afternoon, book Janu's private tour for the early-morning slot before the public arrives.
For an anniversary that wants Aman-quality with more social energy, Janu is the right call. Book the Janu Suite for the Tokyo Tower view from the private balcony, sunset light fills the entire room. Brief the host ahead and they will sequence the dining: Iigura on night one, Sumi on night two for the more casual yakitori-and-cocktail feel, Hu Jing on night three. The hotel will arrange a private morning yoga class on the roof terrace and a guided early-morning walk through the Azabudai Hills park before the office crowds arrive. Anniversary breakfasts in-suite arrive on a Mediterranean-Japanese mezze platter.
For a honeymoon couple who want the new Tokyo opening rather than the institutional grand hotel, Janu is the right opening chapter. Three or four nights here, then a Shinkansen down to Aman Kyoto for the heritage counterpoint, the brand-coherent Aman/Janu honeymoon arc that the Aman concierge will quietly coordinate between the two properties. Janu's wellness centre is the unique selling point: a couples-massage room with two facing tables, a private hammam suite bookable by the hour, and the rooftop yoga studio for sunrise classes. The Janu Suite's private balcony is the most filmable honeymoon address in central Tokyo.
