Tokyu Toyoko Line "Shabon-dama" Train
This specially painted train is called "Shabon-dama (soap bubble)" train.
It is one of the "TOQ-BOX" trains. A company can buy all advertisement space of a "TOQ-BOX" train. Tokyu has four TOQ-BOX trains: two for Toyoko line, two for Den'en-toshi line.
Other railroad companies have such ad-trains. I do not know when it appeared. I think Tokyu already had TOQ-BOX trains twenty years ago.
