Author Tip
Both the British Council and the Institut Franco-Japonais de Tokyo have the headquarters in Iidabashi, along the banks of the old moat. Since you're nearby, you can also enjoy a drink or meal at the Canal Cafe (1-9 Kagurazaka, Shinjuku-ku), just across the road from the hostel. It's one of the few places in Tokyo where you can dine on the water.
Curious Fact
The hostel is steps away from Ushigome-bashi bridge, spanning the outer moat of the old Edo Castle. The bridge was one of the few entrances to the outer citadel areas reserved for the most loyal samurai to the shogun. The Kagurazaka slope at one end of the bridge is a historic geisha district, with several posh ryôtei (an elegant, traditional restaurant) still tucked away in the backstreets.
