Today, July 23rd, afternoon's temporary heavy rain and thunder caused suspension of some railway lines such as Tokyu Toyoko Line.
The suspension of Toyoko Line lead the disorder of the timetable on Seibu Ikebukuro Line through which some of Toyoko Line train goes; those going toward Yokohama and Motomachi-chukagai stopped operating.
Fortunately, I didn't have any trouble on my way home, but I was disappointed at the disorder or suspension of some railways because of the thunder.
