Below the numerical value are a series of Japanese characters including 三十七, which are the date. Read from left to right, they are 3 10 7, or (3x10)+7 = 37. Hirohito became emperor in 1926, which was Showa year 1, making this coin dated 1926+36 = 1962 as Morgensternn said.
The characters to the left of the date are the era name (Showa) and the one to the right I think just means "year".
