일본식 전통 칠기 장어덮밥 우나쥬

Realistic commercial food photography of [unaju, Japanese grilled eel over rice] presented in a traditional rectangular black lacquered bento box with a thin red inner rim, set upon a warm dark wooden table. The box is filled with steaming white rice and covered edge-to-edge with four long grilled eel fillets laid horizontally in parallel, slightly overlapping. The eel is glazed in a glossy caramel-brown tare sauce, showing subtle grill lines, tiny blistered skin textures, char marks, and faint skewer perforations, with appetizing specular reflections. Composition is a close-up three-quarter overhead angle with shallow depth of field, keeping the eel in tack-sharp focus. Softly blurred in the background are three dining accents: a small white ceramic dish with pickled vegetables at the upper left, a dark cylindrical teacup at the upper center, and a lidded black soup bowl with clear dashi broth and a mitsuba leaf at the upper right. Natural warm restaurant lighting with rich contrast. No people, no chopsticks or utensils, no text, no watermarks.
