Bianca seemed to go make-up-free for the 14-hour flight from Florence where she and Kanye were snapped earlier that day.
The Carnival rapper wore a similar white garment over a shirt for his airport look but his featured a black symbol on the chest.
The pair landed in Japan after spending a week in the fashion hotspot of Prato, Italy.
It seemed they spent the majority of their European trip focused on business since Bianca was seen walking into a meeting alongside her husband while holding a sketchbook of designs on June 1.
She was back in her usual skimpy outfits for the meeting, wearing a white open-sided swimsuit that barely covered her assets.
The sighting at the airport comes just days after Kanye celebrated his 47th birthday. But the rapper received a rather unexpected birthday present in the form of a lawsuit filed by his former assistant Lauren Pisciotta.
According to court documents reviewed by Rolling Stone, Laura has accused him of sexual harassment, breach of contract, and wrongful termination.
