"Aman's social sister, Azabudai Hills — the solo trip that includes one good dinner with strangers."
Janu Tokyo opened in March 2024 in the Azabudai Hills development as the first hotel of Aman's new Janu sub-brand — the brand's premise is that Aman's contemplative-silence model can be paired with a more-social, more-restaurant-driven hotel. One hundred and twenty-two rooms, every one with a deep stone bath and a working desk. The asset is the spa — at 4,000 square metres it is the largest Tokyo hotel spa, with a hot-spring-fed onsen, an ice room, a hammam, and the only on-floor Pilates studio in any Tokyo hotel. Eight restaurants and bars under one roof — Janu Mediterranean (the in-house flagship), Iigura (the Japanese counter), Sumi (the omakase counter), Hi-Sai (the Italian rooftop), the bar Janu Lounge, plus three smaller cafés and a bar. Janu Tokyo is the right pick for the solo retreat where the trip is meant to combine the Aman-discipline sleep-and-bath product with a more-active dining-and-bar programme — the eight restaurants offer a different solo-counter dinner each night, the spa is the daily morning ritual, and the Azabudai Hills geographic position connects to the new Mori-developed cultural district (the teamLab Borderless Tokyo digital art space is a 5-minute walk).
Janu Suite (the multi-room flagship) or Janu Premier Suite for the entry-level corner suite.
Use the spa hot-spring onsen at 6.30am — the on-floor onsen is the working asset of the trip. Eat at a different counter restaurant each night (Sumi for sushi on day one, Iigura for kaiseki on day two, Janu Mediterranean for day three). The Pilates studio runs daily 7am classes for solo guests.
Janu Tokyo sits within our broader Top 20 Hotels in Tokyo for a Solo Retreat list. It scored an aggregate 9.7/10 across the three editorial criteria — competitive against the field but, on a solo retreat-specific factors, the angle above is what earned its rank. For the alternatives in the same Tokyo neighbourhood, see Azabudai Hills and adjacent. For a different city entirely, see the related lists below.
If you have already chosen the dates, our editor recommends booking the room twelve weeks ahead. The best suites with the right view orientation go first, and inventory for the popular months is quoted in months, not weeks. Suite-level rooms with private plunge pools or terraces — the ones that earn this rank — are typically the first to sell out.
