Tochomae to Aoyama 1-Chome is the winner in my book too. Did it for 21 nights while I had $2 nights at the nearby Hilton.

And I live about 50 yards from an Oedo line station so I will always go that route to Roppongi even though I end up about ten floors below ground at Roppongi Station. Plenty of eye candy on the escalators there though so no major inconvenience. And they have some of the best placed repeaters in the city on the Oedo line. Almost perfect reception everywhere far underground.

Still I find most taxis have the best reception.

So one more vote for the deep deep underground from this old timer.
