A bit more specific info on my hanami hideaway: it’s called the ‘Tatsudayama Haisuiike Koen’ (立田山配水池公園). A small reservoir was built above the park after the war, when the mountain’s complete deforestation threatened it itself and those who lived near it, both for water supply and flood control. It is still in use to provide water to the Kurokami area. While there, if you have never visited the temple ruins and tombs of the Hosokawa, Taishoji (泰勝寺跡), at Tatsudayama Shizen Koen (立田山自然公園), you should. Their English-language brochures are informative. Access is the road which runs just next to Kumadai’s north campus. - William
