Recommendations based on your requirements (
convenient location + focus on high quality amenities)
- Aman (Marunouchi)
- Shangri-La (Tokyo Station / Nihonbashi)
- Andaz (Toranomon)
- Prince Gallery (Akasaka)
- Conrad (Shiodome)
Edit: might also be worth looking into the brand new Okura in Toranomon. Not the most convenient location but hard product looks fantastic (especially the Heritage wing - https://theokuratokyo.jp/en/stay/heritage/)
, with a nice spa as well.
