Around 35°40’12.39″ N 139°45’49.10″ E – right across from the main entrance to Ginza SIX is the entrance to the UNIQLO Annex Store on Rt. 15.
UNIQLO has opened a new café in the store – UNIQLO COFFEE Ginza. This site has an excellent review. The new café isn’t in the main UNIQLO building on the corner at 35°40’24.21″ N 139°45’55.78″ E – it’s a bit southeast in the newer Annex store on Rt. 15.
Note that there is no street-level Ginza Station – you will either have to exit Ginza Station at one of the street-level portals, or else go to Yurakucho Station, exit the east side, then head east down sidewalks.
From Korakuen Station exit to the south, walk across the elevated platform, past Tokyo Dome, down the stairs the right, then 2 blocks west, then 1 block south. From Suidobashi Station head directly west approx. 3 blocks.
There’s not a whole lot to do here, but it does have some interesting restaurants. If you have time for lunch or dinner and are in the area, pop in and check it out.
