Natalie Roser delighted her Instagram fans during the trip with a revealing snap.

The 27-year-old flaunted her toned back and very pert derrière in a skimpy black swimsuit.

Standing in a luxurious spa at the Peninsula Hotel in Tokyo, Japan, Natalie drew attention to her enviable figure.

A racy black swimsuit highlighted the stunner’s toned back, lithe arms and toned bottom.

Beaming at the camera, Natalie’s semi-wet blonde locks fell effortlessly and she appeared to have gone makeup-free.

The editorial model captioned the photo: ‘The water was calling my name Sad to be leaving @peninsulahotels #Tokyo for now, but excited about exploring #Kyoto!
