7:15 PM PT -- We just got the first pics from Nicolas and Riko's wedding which was held at the Wynn Hotel in Las Vegas.
Nic's rep Shannon Barr tells TMZ ... the date, February 16, was special for the groom ... it's Nic's late father's birthday. Riko -- who Nic met over a year ago in Japan -- was wearing a handmade Japanese bridal kimono, and Nic was rocking a tux by Tom Ford.
We're told the ceremony included traditional Catholic and Shinto vows, but in true Nic fashion they also kept things unique ... adding some poetry from Walt Whitman and Haiku.
Seemingly acknowledging, his 5th time down the aisle might shock some folks, Nick says, "It's true, and we are very happy."
BTW, his ex-wife Alice Kim and their son, Kal, celebrated with the happy couple after the ceremony.
Nicolas Cage is going back to the wedding well ... he got married for a whopping 5th time, and once again he tied the knot in Sin City.
The 56-year-old actor married 26-year-old Riko Shibata last month in Nevada, according to the Clark County Clerk's Office. The records show Riko took Nic's last name, and on Feb. 16 they said "I Do."
Nic, who lives in Las Vegas, announced his engagement to Riko back in August after proposing over FaceTime. Riko was in Japan when he popped the question, so Nicolas sent the engagement ring via FedEx.
It's the 5th marriage for Nicolas ... and the union comes less than 2 years after his last marriage to Erika Koike ended in divorce after only 4 days. DailyMail was first to report the news of his new bride.
