When the Warriors Took Over and Moved the Capital to a Beach

The War That Ended the Court's Monopoly The Genpei War of the 1180s, fought between the Taira and Minamoto clans, is the founding conflict of samurai Japan and the subject of its greatest war epic. The Taira had risen by playing court politics; the Minamoto destroyed them, ending at the sea battle of Dan-no-ura where the Taira were annihilated and the child emperor drowned with them.

Minamoto no Yoritomo, the victor, made a decision with enormous consequences: rather than moving to Kyoto and becoming a courtier, he stayed in the east and established his government at Kamakura. The emperor and court remained in Kyoto with their ceremonial authority intact; real power sat elsewhere. That division between symbolic and actual authority became a durable feature of Japanese politics.

Kamakura was chosen for defence — hills on three sides, sea on the fourth, and access through narrow cut passes that could be held. Walking those cuttings today is the most direct way to understand why the town is where it is.

A New Religion for a New Class The court's Buddhism was elaborate, expensive and textually demanding. What arrived in this period suited a different clientele.

Zen came from China with an emphasis on direct practice and discipline rather than doctrine, and it appealed strongly to a warrior class that valued exactly those things. The great Kamakura Zen temples were founded under shogunal patronage, and Zen's influence subsequently spread far beyond religion into garden design, tea, ink painting, archery and swordsmanship.

At the same time the Pure Land schools were spreading among ordinary people with a far simpler proposition: recite the name of Amida Buddha in faith and be reborn in the western paradise. No literacy, no monastery, no wealth required. Those schools are, by number of adherents, the largest in Japan today. And Nichiren, preaching in this period and thoroughly antagonising the authorities, founded the tradition that bears his name.

A single century produced most of the Buddhist landscape Japan still has.

The Mongols In 1274 and again in 1281, Kublai Khan sent invasion fleets against Japan, the second reportedly among the largest naval operations in premodern history. Both failed. Japanese defences held the beachheads in Kyūshū long enough for storms to wreck the fleets at anchor.

Those storms were named kamikaze — divine winds — and the belief that Japan was under supernatural protection entered the national self-understanding, with consequences that reached grimly into the twentieth century.

The shogunate won and was ruined by it. A defensive war produces no conquered land, and the warriors who had fought expected reward. Unable to pay them, the regime lost the loyalty it depended on, and it fell within a few decades.

The Great Buddha and the Missing Hall The bronze Amida at Kōtoku-in, cast in the mid-thirteenth century, sits in the open air. It was originally housed in a hall, and the hall was destroyed — by storm and by tsunami, in accounts that vary — and never rebuilt.

That accident produced the image everyone knows. A colossal seated Buddha under open sky, weathered green, with the hills behind it, is a different proposition from the same figure in a dark hall, and it is arguably the most affecting large Buddhist image in Japan for exactly that reason.

Kamakura Now The town is an easy trip from Tokyo and is deservedly popular, which means the famous sites are busy. What repays effort is the periphery: the hiking trails over the wooded ridges that link temples, the bamboo grove at Hōkoku-ji, the hillside terraces of Hase-dera, and the narrow cut passes that were the town's gates.

Going on a weekday and walking a ridge trail between two temples gets you the Kamakura that explains why a warrior government chose the site, which the main street on a Sunday does not.
