Saturday morning around 11:30 I woke up to a helicopter flying over my house. A rare thing in Japan. Turns out that there was a train accident at Koyoen Station near my house. It appears to me that the train was coming into Koyoen Station and car in the rear jumped the track at the switch. The newspaper article does not mention any injuries.
Hankyu has set up a bus service between Shukugawa and Koyoen stations. Anyone else who wants to come to Koyoen from Osaka or Kobe might also consider taking the Hanshin train to Nishinomiya station and take the bus.
Derailment is 脱線 (だっせん) in Japanese.
