I liked the Chinzan-so, but the location was a bit of an issue. Finding your way back from the metro station and then walking up the hill to the hotel was not exactly straightforward ... as I learned once on my way back. I like the hotel grounds and waking up in the morning (early sun) and seeing the grounds and the old main construct on it; it makes for a very good way to wake up. The gym there is small but decent. With the supply of Evian water bottles (for free

) and any clothes or shoes you need to work out, the gym satisfied me. (The green full-size toothbrushes this hotel has seem to last forever.

)
Some negotiated rates include a one-way car drop-off on at least weekeday mornings.
I have no experience with the newer Four Seasons in Tokyo.
