I know some japanese families also here in UK and they rather go back to japan and live there than stay here in UK.

Well one of them is already back in japan, the other one still have 3 years to stay in UK and one other jap girl who married a brit wants to stay in UK but she's different and other jap families don't even like her lol (she's so bossy , didn't like jap guys so she married a brit to be her hubby to under (ander de saya)
