Here are a few manner of bizarre posters that appeared in the Tokyo subways between 1976 and 1982…

Clearly show your train pass (September 1978)
The image of Napoleon holding a partially concealed train pass is meant to remind passengers to clearly show their train passes to the station attendant when passing through the gates. The dictionary page in the background appears to be a reference to Napoleon’s famous quote, “The word ‘impossible’ is not in my dictionary.”

Do not rush onto the train (April 1979)
This poster advises passengers not to rush onto the train at the last moment. The text (かけこみ禁寺） is a play on the words かけこみ禁止 (kakekomi kinshi – “don’t rush onto the train”) and かけこみ寺 (Kakekomi-dera – Kakekomi temple), which has long been known as a sanctuary for married women fleeing their husbands.

Don’t forget your umbrella (October 1981)
The text at the top of this poster — which shows Jesus overwhelmed with umbrellas at the Last Supper — reads “Kasane-gasane no kami-danomi” (lit. “Wishing to God again and again”). The poster makes a play on the words “kasa” (umbrella) and “kasane-gasane” (again and again).
