Is there a Japanese 'community' of sorts in Florence?

Hi there, We are moving to Florence with our two 6 year olds in November, I am Dutch, she is Japanese, I have traveled for the last 25 years all over Asia so I am ok with moving to yet another country. Question is, is there a Japanese community in Firenze? Would love for my wife to have a few Japanese speaking people, not in the least for the kids to stay multi lingual. Another question, where would you recommend to rent a house away from the centre, but not to far from nice restaurants :) ? Your assistance is appreciated. Thanks! JP.
