Poster of the Japanese Communist Party (日本共産党).

I know they have issues with their ideologies but the poster looks cool!

The text reads,

希望をあなたと共に; 日本共産党; Change裹金政治

Which roughly translates to,

‘Hope together with you; Nihon Kyōsantō; Change the gold-wrapped politics’.

(The last line is likely a reference to the financial scandals of the current ruling Liberal Democratic Party)
