noun
Collar of the Supreme Order of the Chrysanthemum
The highest possible honor in the Japanese honors system, awarded only to members of the imperial family and a very small number of foreign heads of state. The full name is rarely used in everyday conversation; it is a formal, domain-specific term.
大勲位菊花章頸飾は、日本の最高位の勲章である。
The Collar of the Supreme Order of the Chrysanthemum is Japan's highest order.
The Grand Cordon of the Supreme Order of the Chrysanthemum, a slightly lower but still extremely high honor. The collar is even more exclusive.
The name is composed of 大勲位 (supreme order of merit), 菊花章 (chrysanthemum decoration), and 頸飾 (collar). The chrysanthemum is the imperial crest of Japan.
