After a lot of weekends in Tokyo, its difficult to know where else to visit. Until I stumbled upon this Tokyo tourism webpage with a list of recommended walks around Tokyo. Going through the whole list, I went for the “Discover old Edo (Half Day) [Monzen-Nakacho]” route. This involves taking the Toei line all from Yoyogi JR all the way to Kiyosumi-Shirakawa station.
A short walk away is the Kiyosumi Garden, which cost 150Y to enter, which is not too bad considering the gardens are quite well maintained, and the lake there filled with turtles and the largest Kois I have ever seen, some of them size of a full sized cat. This would make a nice place to do some landscape photography with tripods. The rest of the route is a nice walk, but nothing special.
