In Japan, as earlier in China, the mythical Phoenix was adopted as a symbol of the imperial household, particularly the empress. This mythical bird represents fire, the sun, justice, obedience, fidelity, and the southern star constellations.
According to legend (mostly from China), the Hō-ō appears very rarely, and only to mark the beginning of a new era -- the birth of a virtuous ruler, for example. In other traditions, the Hō-ō appears only in peaceful and prosperous times (nesting, it is said, in paulownia trees), and hides itself when there is trouble. As the herald of a new age, the Hō-ō descends from heaven to earth to do good deeds, and then it returns to its celestial abode to await a new era. It is both a symbol of peace (when the bird appears) and a symbol of disharmony (when the bird disappears). In China, early artifacts show the Phoenix (female) as intimately associated with the Dragon (male) -- the two are portrayed either as mortal enemies or as blissful lovers. When shown together, the two symbolize both conflict and wedded bliss, and are a common design motif even today in many parts of Asia.
鳳 = Fèng, Male Phoenix' '凰 = Huáng, Female Phoenix
The Chinese compound term Fèng Huáng means Phoenix. The Feng Huang was believed to control the five tones of traditional Chinese music and to represent the Confucian virtues of loyalty, honesty, decorum and justice. Its image first appears on Shang artifacts of China’s Western Zhou Period (11th century BC to 771 BC).
The symbolism of the Chinese Phoenix (Fèng Huáng) is strikingly similar to the symbolism of the mythological Red Bird (Chn. = Zhū Qiǎo 朱雀 or Zhū Niǎo 朱鳥), also of Chinese lore. In Japan, the Red Bird is pronounced Suzaku (same Chinese characters). I believe the Red Bird is the same creature as the Phoenix, although I may be wrong. The Red Bird is one of four legendary Chinese creatures guarding the four cosmic directions (Red Bird - S, Dragon - E, Tortoise - N, and the Tiger - W). The four appear during China’s Warring States period (476 BC - 221 BC), and were frequently painted on the walls of early Chinese and Korean tombs to ward off evil spirits.

The Arabian-Western Phoenix, if you recall, is a solidarity creature -- only one of its kind. When it dies, it dies in flames, and from the ashes is born the next phoenix.
