Japanese 10 Yen Coin [gelöst]

I have several 10 Yen Japanese coins and would like to date them.  I cannot find a website that allows me to convert a Japanese script date to Gregorian or Julian calendar date.  I hate to ask for several date analyses from you experts so can you analyze this one coin and point me to a way to do the conversion of other coins on my own?  I know they are Showa period coins or at least I believe they are.  Thank you in advance.   

Look no farther than Numista.
