The park is built around a 150-year-old wisteria and long tunnels of hanging wisteria blossom. Fans identify it as the model for the wisteria-covered mountain in the Demon Slayer final selection arc. This is fan identification rather than an official statement.
值得去的理由
The wisteria tunnels are worth the trip on their own merits, quite apart from the series.
什麼時候去
The wisteria season in late April and May is extremely busy, and it is also the only time the connection makes visual sense.
先知道會比較好
Outside the wisteria season the park is a different place entirely. Admission and opening hours change with the season, and the park has its own JR station.
