Nice piece! I doubt it is solid gold, and believe the 24kt refers only to the gold overlay/inlay. My best guess is the the exterior metal on the box is shakudo, a typically Japanese alloy of about 96% copper and 4% gold. Properly patinated, this alloy shows a stong black color, ranging from a deep purple black (preferred) to a greenish dark gray when the gold content is low, it was not well patinated, or the original patination has deteriorated.
