Located within the Opus Arisugawa housing complex in central Tokyo, the apartment's interior was renovated to combine design influences from Japan and Scandinavia – a trend known as Japandi.
A mixture of deep indigo tiles and paper yarn rugs made from Finnish birch but embroidered with Japanese textile-style patterns cover the floors.
"The interiors reflect the studio's cross-pollination of Japanese and Scandinavian design ideas, drawing inspiration from both cultures and reinterpreting them in new ways," said the firm.
The hallway leads to an open-plan living room filled with interiors in neutral tones, including cool stone floors and sleek furniture finished in smoked oak, oiled pinewood and soft wool.
Japanese Ōya stone was used for the columns that divide the living area and brightly lit kitchen, which includes tactile wooden cabinetry.
A minimal dining space with black-stained ash chairs also features alongside the kitchen.
The apartment's three bedrooms also have a mixture of refined textures and shapes, while the singular pared-back bathroom displays a statement wooden bathtub at its centre.
"We worked carefully with the zoning and the transitions between the rooms in the apartment to create an evocative yet calm, welcoming and comfortable atmosphere," said OEO Studio.
Founded in 2003, OEO Studio has created a number of similar projects including a Tokyo restaurant that references both Danish carpentry and Japanese gardens in its interiors.
The firm recently created a cafe and shop at Designmuseum Denmark that pays homage to architect Kaare Klint's original design.
