Toshima Garbage Factory

In recent years, due to increasing environmental awareness and improved production methods, Japan has been suffering from a severe shortage of waste. To save Tokyo's garbage collectors from unemployment, the city's ward administrations have set up garbage factories such as this one here in Toshima-ku.

Alternatively it's possible this is one of the places where Japanese television is produced. Whatever, it's the location of that whacking great tall chimney to the north of Ikebukuro Station.
