Hoshino will meet with the lucky groom three weeks before the big day to plan their dream wedding, and on the day their hair will be professionally styled.
The ceremonies will all be held in the up-market Odaiba district of Tokyo, and while they will mimic real, traditional weddings, the "posed only" events will not be legally recognised.
The entire event will last for two hours including the all-important rehearsal, walking down the aisle arm-in-arm, and the ceremony which will be performed by a master of ceremonies.
On the Ambitious website, a comment attributed to Hoshino says: "Come enjoy your real wedding with me and be happy together".
