Located in Bunkyō-ku, Tokyo Dome is a large entertainment complex (including shops, restaurants, a hotel, a spa, an amusement park and the Tokyo Dome baseball stadium) easily accessible by train (the JR Chūō-Sōbu line) or by subway (Toei Mita line), via the Suidōbashi Station.
Milky Way is a 140 meters long passage located near the LaQua spa, with spectacular decorations in blue, yellow and violet. For me, this is one of the most romantic places in Tokyo during this time of the year... and I think that goes for many other people, because I found there many couples strolling under the lights...
Travel Tip:
The Milky Way lights are lit at Tokyo Dome City until February 14 - the Valentine's Day - between 5PM and 11PM.
