A little slice of Calm and serenity, literally in the middle of Tokyo's business district. There were hordes of turtles sunbaking on rocks, and koi so bold they'd all but eat from your hands.
Built in Enpoh rokunen (1678), Kyu Shibu-rikyu is one of the oldest remaining Daimyo gardens in Japan. Smaller by far than it's neighbour, Hama-rikyu, I think this is actually my favourite park in Japan - it is a place where business men hang out and eat their lunch, while old retirees practice their painting and sketching. It is as it should be - a park kept in the manner it was made, but enjoyed in entirely current ways.
