According to witness tweets, this "man" appears to appear at Kichijoji Station, Akabane Station, Ikebukuro Station, Shibuya Station, Kokubunji Station in Tokyo, Kawaguchi Station and Tokorozawa Station in Saitama Prefecture.
The man wears a black top hat and a black coat, and is walking with a "radish" attached to the tip of a black lead for dogs. It seems that the appearance of the man differs depending on the witness, such as "I was pulling it on (?)" And "I had a batch of" I love (heart symbol) Saitama "on the hat."

A "man who walks a radish" who appears in a wide area from Tokyo to Saitama and is called "old man", "nice gentleman", and "young boy" by witnesses. Perhaps there are multiple people. I don't think he's a bad person (?), But I'm curious about his identity ...!
