Wallpaper - Japandi Sea

Designed by Janelle Penner, our Japandi Sea wallpaper brings a rhythmic wave motif to life through layered, concentric arches in teal, slate blue, and soft neutral tones. The painted-looking texture within each curve creates a gentle sense of movement across the wall, balancing Japanese wave inspiration with clean Scandinavian simplicity. The repeating geometric arches offer visual depth without overwhelming a space, making it an expressive yet grounded accent. Like all Wallism mural wallpapers, this design is made-to-measure, PVC-free, and printed on paper with a subtle physical surface structure.

In the room

We find this wave repeat particularly effective when given room to breathe across a full wall. In a bedroom, it works naturally behind a headboard, where the horizontal flow of the arches frames the bed and anchors the layout. In a living room or dedicated home office, the balanced rhythm provides visual interest without distracting from daily routines. Because the pattern relies on soft, overlapping curves rather than high-contrast geometric lines, it also sits comfortably on larger uninterrupted walls in an open-plan living space or a tranquil nursery.

Styling it

To let the fluid pattern take centre stage, we suggest pairing this design with quiet, uncluttered interior choices:

• Choose furniture in pale ash, blonde oak, or painted off-white finishes to reflect the airy neutral ground of the wallpaper.
• Keep surrounding upholstery and soft furnishings plain or lightly textured, avoiding competing bold prints.
• Incorporate simple matte black or brushed bronze hardware to echo the clean, graphic lines of the arch shapes.

Colour combinations

The wallpaper is built around a palette of coastal teal, dusty slate blue, and warm off-white. When choosing colours for adjacent walls, woodwork, and skirting, soft creams or muted chalky whites keep the room light and cohesive. For a more enveloping look, you can draw directly from the deeper slate and teal tones in the motif, using them on neighbouring painted surfaces, built-in joinery, or accent cushions to tie the entire room together.
