Oh, wait, you too work in Akasaka? :)
naa - i'm inbetween Yotsuya and Kojimachi, but i run around that area most days
It's a short walk away from our main office, issue being most days i'm at clients on their site so usually means i'm either in the Yaesu side of Tokyo or around Otemachi.
But yeah, we aren't far away - we should say hi or something during a lunchtime or something
