A Japanese woman in her 20s running in profile view against a pure white background, minimalist modern style. She wears a white cropped half-sleeve fitted t-shirt, denim shorts, and white sneakers. Her long straight black hair streams behind her horizontally, frozen in dynamic motion. Side view composition capturing her right side, running from right to left. Both feet are off the ground in mid-stride showing athletic running form, right leg extended forward with bent knee, left leg pushed back with toes pointed. Her arms pump vigorously with left arm bent forward at 90 degrees and right arm bent backward. Her torso leans slightly forward with engaged core showing athletic posture. Expression shows focused determination with eyes looking straight ahead, mouth slightly open breathing naturally. Her body creates a powerful diagonal line suggesting speed and energy. Photographed from a side angle at waist height to emphasize the dynamic running pose. Bright even lighting eliminates harsh shadows while maintaining subtle ground shadow for spatial awareness. The pure white seamless background amplifies the sense of motion and freedom. Sharp focus on the subject with perfect exposure showing fabric movement and muscle definition. Ultra-clean commercial photography style ideal for fitness and lifestyle stock imagery.
