A Century of War Produced Japan's Most Beautiful Buildings

A Hundred Years of Fighting The Sengoku period — the age of the country at war — runs from the mid-fifteenth century, when the shogunate's authority collapsed, to the beginning of the seventeenth. Provincial lords, the daimyō, fought continuously for territory, retainers changed sides, and a lower-ranking commander overthrowing his superior became common enough to have its own name.

It is the setting for most of what the rest of the world thinks of as samurai Japan, and it is worth being clear that it was a period of enormous violence and disruption. It is also, unavoidably, one of the most compelling stretches of history anywhere, with a cast of characters that Japanese popular culture has never stopped retelling.

The Guns Portuguese traders reached Japan in the 1540s and brought matchlock firearms. Japanese smiths — already exceptional metalworkers — reverse-engineered and mass-produced them with remarkable speed, and within decades Japan had a very large number of guns.

The consequences were architectural as much as tactical. Firearms made older hilltop fortifications inadequate and drove the development of the castle form now recognised worldwide: massive sloped stone bases that resist both cannon and earthquake, multiple concentric baileys, and gate sequences that force attackers into confined spaces under fire.

Oda Nobunaga's use of massed volley fire against cavalry is generally cited as the moment the new weapon settled the shape of Japanese warfare.

Three Men, One Lifetime The unification is traditionally told through three figures and a proverb about a cuckoo that will not sing. Nobunaga would kill it. Hideyoshi would make it want to sing. Ieyasu would wait until it did.

Oda Nobunaga broke the old order with ruthlessness and innovation, destroying the militant monastic institutions and taking control of central Japan before being killed by one of his own generals. Toyotomi Hideyoshi, who rose from peasant origins — genuinely remarkable in that society — completed the unification, conducted a nationwide land survey, disarmed the peasantry, and froze the social classes in place. Tokugawa Ieyasu waited, won the decisive battle at Sekigahara in 1600, and founded the shogunate that ruled for two and a half centuries.

The Momoyama Style The brief period at the end of the wars, under Hideyoshi, produced an art of spectacular extravagance: gold-leaf screens, bold colour, enormous scale, castles as displays of power rather than only as fortifications.

It coexisted with the exact opposite. Sen no Rikyū, Hideyoshi's tea master, was refining a tea aesthetic of extreme austerity — tiny rooms, rough bowls, an entrance so low that everyone had to bow. That a warlord commissioning gold-leaf audience halls also patronised a man making two-mat tea huts is one of the genuine puzzles of the period, and it ended badly: Rikyū was ordered to take his own life.

The Castles That Survive Only twelve original castle keeps survive in Japan. The rest were dismantled in the nineteenth century, burned, or destroyed by bombing, and most of the famous ones — including Osaka — are twentieth-century concrete reconstructions.

Himeji is the great survivor: never burned, never taken, restored rather than rebuilt, and a UNESCO World Heritage site. Walking it properly means following the approach route through the gates, and it becomes obvious very quickly that the path doubles back, narrows, and exposes you repeatedly. The beauty is real and it is entirely secondary.

The adjacent garden, Kōko-en, is worth the extra ticket, and knowing that only twelve keeps are original changes how you read every castle you see afterwards.
