c. 250 — 538 CE / 古墳時代
The Tomb Age
The keyhole-shaped tomb mounds rise from the Yamato plain in this century like inverted ships of earth. The largest holds an emperor whose name we still pronounce with care. Bronze mirrors are buried beside him, polished to receive a face that will not return.
RUBY ERA · 大和朝廷
古
538 — 1185 CE / 飛鳥・奈良・平安
The Capitals of Stone and Brush
Buddhism arrives by ship; the brush is taught in palaces; a thousand poems are written by women whose names are sometimes lost and sometimes kept. The court at Heian-kyō learns that a quiet life can outlast a loud empire.
SAPPHIRE ERA · 平安京
1185 — 1603 CE / 鎌倉・室町・戦国
The Long Civil War
Warriors govern from the saddle; tea is taken in small rooms; a sword is folded and folded until it rings. The country fractures and reassembles four times in three centuries. The land remembers each fracture as a fault line.
SAPPHIRE ERA · 武家政権
武
1603 — 1868 CE / 江戸時代
The Closed Garden
Two centuries of relative peace; the gates closed; a culture turned inward and made itself dense. Floating-world prints, dense kabuki, the rise of the merchant class. The country is, for a moment, an island of its own making.

1868 — present / 近現代
The Restless Modern
Steam, then electricity, then code. The teenagers of Harajuku invent themselves daily. The bullet train cuts the country into two-hour journeys. The Yamato spirit, always patient, watches it all and writes nothing down.
