Johnny Depp and Amber Heard were spotted in Tokyo, Japan today in a rare public appearance, and Amber looked comfortable and relaxed with Johnny's two children at Narita International airport.

The sighting marked the first time Amber has been seen in public with Johnny's kids, 14-year-old Lily-Rose and 11-year-old Jack.

Amber wore a long, flowing white maxi dress, tan-rimmed shades, and her blonde hair in a simple ponytail. She walked with her arm protectively around Jack, with Lily-Rose following close behind through the busy terminal, E! News reports.

50-year-old Johnny showed off his quirky style with a cowboy vibe, which is pertinent because he is in Japan to promote his new film "The Lone Ranger," a Western movie.

Johnny rocked a brown fedora, purple-tinted shades, a black vest over a loose white shirt, blue jeans with a few bandanas sticking out of the pocket, and black boots. He also accessorized with many necklaces, bracelets, and rings.

At the airport, Johnny stopped to greet a huge crowd of fans at Narita International airport. At one point, he got down on one knee to shake hands with a little Japanese girl, and even gave her a small peck on the cheek. Fans squealed with delight.

Heard has been spotted accompanying Depp on his promotional tour before. She flew all the way to Moscow, Russia, to join him for "The Lone Ranger," screening and went out to dinner with him after.

The notoriously private couple met on the set of "The Rum Diary" in 2010, but were not romantically linked until Depp split with his partner of 14 years and mother of his two children, Vanessa Paradis. Depp and Heard have been dating since last year.
