A Japanese woman in her twenties is wearing medieval o-yoroi (large armor). Her face combines the grace of noble birth with the strength of a warrior charging into battle. Her mouth is tightly pressed together, and her gaze is defiantly fixed into the distance. The armor she wears is a magnificent o-yoroi (large armor), with black lacquered kozane (small plates) carefully adorned with scarlet leather straps. Large sleeves stretch out from the shoulders to deflect arrows, their surface decorated with gold lacquer and patterns of waves and plovers. The front of the torso is reinforced with a leather tsurubashiri (string running) to prevent chafing when drawing a bow. The helmet is a star-shaped helmet worn low over the eyes, with numerous studs (stars) hammered into the base. Above the brow guard, powerful golden 鍬形 (helmet crest) stretches out on both sides, and in the center shines a shining figure* engraved with a gold-plated dragon. The pose shows her on horseback, ready to release her arrow. Her body is twisted greatly, her left arm firmly supporting the bow, and her right arm fully pulling the string. Her waist is stable in the saddle, and her feet are firmly planted in the stirrups. Her gaze is directed toward the tip of the arrow, focused on that point. The composition captures the horse from the side at a slight angle, emphasizing the sense of oneness between her and her horse. The lighting is under a clear blue sky, with strong sunlight reflecting off her armor and helmet, making the scarlet decorative thread and golden 鍬形 (helmet crest) shine brilliantly. In the background is a vast grassland, and in the distance a range of mountains are visible in the haze. Beneath her feet, the soil with hoofprints is realistically depicted.
