```text
A wide cinematic hero image for a Japanese luxury furniture website (16:9 horizontal). Scene: an upscale Japanese living room interior with premium 匠大塚 (Takumi Otsuka) furniture - a deep navy chesterfield-style sofa, a solid walnut coffee table, a luxurious Persian rug, framed art on cream walls, golden hour light from floor-to-ceiling windows, a tall standing lamp with warm glow. Subtle dust particles in the air, slight camera dolly forward feel. Center-left text overlay in elegant Japanese serif font: "本物の家具と、" (white with subtle drop shadow). Below: "本物の暮らしを。" (larger, slightly more spacing). Right side: small "匠大塚" logo in gold. Bottom: thin horizontal line and small text "TAKUMI OTSUKA - Since 1965". Style: editorial luxury, Architectural Digest level, refined Japanese craft aesthetic. No watermarks, no English text other than specified.
