Art style: 3D Pixar.
Interior of a sleek, modern Shinkansen bullet train from a low angle. Nicolas and Olivia are seated by a large window. Polo is leaning his weight against the pane, his fluffy face and black nose pressed against the glass. Outside, the majestic snow-capped peak of Mount Fuji rises against a clear blue sky above green hills.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image in the following art style:
Pixar-style 3D computer animation (Pixar / Disney feature-film look) — fully volumetric 3D rendering with rounded dimensional forms, soft subsurface-scattering skin, physically based materials, soft global illumination, warm cinematic key light, gentle depth of field, vibrant family-friendly colours. CRITICAL: EVERY element — characters, foliage, trees, animals, water, sky, props and the entire environment — must be rendered as polished 3D CGI with real depth and form. This is NOT flat 2D illustration, NOT a watercolour or storybook painting, NOT cel-shaded anime.
Every surface, skin, fabric, material, and environmental element must be rendered in this idiom.
