Horikiri Iris Garden
This garden, not so large, is a 10-minute walk from the nearest railway station (Keisei Line Horikiri-shobuen Sta.). If you happen to be using the Keisei Line in the iris season and have time, you might consider visiting here.
About 6,000 irises composed of 200 cultivars are planted in this Japanese-style garden and bloom around early to mid-June. During this period, the Iris Festival is held here, and the opening hours will be extended to 9AM-6PM.
It's an 8-min walk from Keisei Line Horikiri-shobuen Station.
The Horikiri district had been a place famous for private-run iris gardens from the feudal times to the early Showa era. Horikiri Iris Garden, or Horikiri Shobuen (堀切菖蒲園), is the only remaining iris garden in this area. The predecessor of this garden was also founded as a private-run garden in the Meiji era and was larger than now but now it's run by the local government.
