If you thought Japan was only about sushi, samurais and cherry blossoms, think again. This roundup of 10 crazy historic nuggets reveals the nation’s wilder past— from forbidden feasts and gender‑bending theater to secret atomic projects and grim wartime trophies. Buckle up for a whirlwind tour through the quirkiest chapters of Japanese history.
10 Crazy Historic Highlights From the Land of the Rising Sun
10 It Used To Be Illegal In Japan To Eat Meat
From the mid‑seventh century onward, the Japanese authorities imposed a sweeping prohibition on the consumption of animal flesh—a ban that flickered on and off for more than twelve centuries. Inspired largely by Buddhist doctrine, which condemns the taking of life, Emperor Tenmu issued a decree in 675 that outlawed eating beef, monkeys, and domesticated animals, even threatening death for violators.
The original edict limited the ban to the months of April through September, but subsequent statutes and religious customs effectively extended the prohibition to most meat year‑round, especially beef. It wasn’t until the arrival of Christian missionaries in the sixteenth century that the idea of eating meat began to re‑emerge, though another ban resurfaced in 1687, leaving a handful of defiant eaters still indulging.
Finally, in 1872, the Meiji government officially rescinded the centuries‑old restriction, and even the emperor himself took to the table as a meat‑eater. While some monks balked at the change, the ancient taboo gradually dissolved, paving the way for modern Japanese cuisine.
9 Kabuki Was Created By A Crossdressing Woman
Kabuki, the flamboyant theatrical tradition famous for its all‑male casts, actually began with women on stage. Its founder, the priestess‑turned‑performer Izumo no Okuni, dazzled audiences by dancing and acting while dressed in male attire. Her bold, sensual routines sparked a craze, prompting courtesans to copy her style in all‑female troupes.
The phenomenon, dubbed “women Kabuki,” drew invitations from powerful daimyōs who hired these troupes for private performances in their castles. The public adored the raucous spectacle, but the shogunate grew increasingly uneasy.
In 1629, after a riot erupted at a Kabuki show in Kyoto, authorities banned women from the stage. Male actors then assumed female roles, cementing the tradition we recognize today.
8 Japan’s Surrender In World War II Almost Didn’t Happen
When Emperor Hirohito delivered the famed “Jewel Voice Broadcast” on August 15, 1945, announcing Japan’s unconditional surrender, the recorded message nearly never left the Imperial Palace. That very night, a faction of hard‑line officers, refusing to accept defeat, launched a coup.
Led by Major Kenji Hatanaka, the rebels seized the palace for several hours, intent on destroying the broadcast recording. Their troops ransacked every corner, yet the tape remained missing.
In a stroke of luck, a palace aide smuggled the precious recording out in a laundry basket. Hatanaka then cycled to a nearby radio station, hoping to broadcast his own message, but technical glitches thwarted him. Defeated, he returned to the palace and took his own life.
7 Samurai Sometimes Tested Swords By Attacking Random Passersby
During medieval Japan, a samurai’s honor hinged on his blade’s ability to cleave an opponent in a single strike. To verify a new sword’s sharpness, warriors engaged in a practice called tsujigiri, or “crossroads killing,” where unsuspecting pedestrians became impromptu targets.
While many samurai tested their swords on criminals or corpses, the most reckless would strike random commoners strolling by night‑time crossroads. Such incidents were rare, yet the practice grew notorious enough that the authorities outlawed it in 1602.
Historical records from the early Edo period (1603‑1868) recount that certain intersections in what is now Tokyo saw nightly fatalities due to tsujigiri, prompting the ban.
6 Japanese Soldiers Once Cut Off Ears And Noses For War Trophies
During Toyotomi Hideyoshi’s two invasions of Korea (1592‑1598), Japanese troops committed brutal acts that may have claimed up to a million Korean lives. Among the horrors, warriors collected the heads of slain foes as trophies.
Transporting whole heads proved cumbersome, so soldiers opted to seize ears and noses instead, which were easier to carry back home. These grisly souvenirs were later enshrined in monuments known as “ear tombs” and “nose tombs.”
The most famous of these is the Mimizuka in Kyoto, housing tens of thousands of such trophies. Another site in Okayama once held 20,000 noses, which were repatriated to Korea in 1992.
5 Father Of The Kamikaze Committed Seppuku To Atone For The Pilots He Helped To Kill
By October 1944, Vice Admiral Takijiro Onishi championed the desperate kamikaze strategy— suicide attacks where pilots deliberately crashed into Allied vessels. He believed the shock would force the United States to capitulate, even offering to sacrifice 20 million Japanese lives to secure victory.
When Emperor Hirohito announced Japan’s surrender in August 1945, Onishi was consumed by guilt over the thousands of young men he had sent to their deaths. Believing only self‑immolation could atone, he performed seppuku on August 16.
In his farewell note, Onishi apologized to “the souls of those bereaved dead and their bereaved families” and implored future generations to pursue world peace.
4 The First Japanese Convert To Christianity Was A Murderer On The Run
In 1546, a 35‑year‑old samurai named Anjiro found himself evading the law after killing a man in a duel. He hid in the bustling port of Kagoshima, where Portuguese sailors took pity on the fugitive.
The Portuguese escorted him to Malacca, where he learned the language and was baptized as Paulo de Santa Fe, becoming Japan’s first documented Christian convert. He later accompanied Jesuit missionary Francis Xavier on a 1549 expedition back to Japan.
Although Xavier’s mission faltered and Anjiro eventually disappeared— believed to have turned pirate— his story marks a remarkable, if shadowed, footnote in the nation’s religious history.
3 The Portuguese Slave Trade Resulted In Japan Abolishing Slavery
Shortly after the Portuguese first made contact with Japan in the 1540s, a lucrative trade in Japanese slaves emerged. Local merchants sold fellow countrymen to Portuguese buyers, who then shipped them to Europe and other Asian colonies. The trade grew so extensive that even Portuguese settlers in Macau owned Japanese slaves.
Jesuit missionaries decried the practice, persuading the Portuguese crown in 1571 to outlaw the enslavement of Japanese. Though the decree faced resistance, it sparked debate.
Japanese warlord Toyotomi Hideyoshi, already notorious for enslaving Koreans during his invasions, was outraged by the foreign trade in his own people. In 1587, he issued a ban prohibiting the sale of Japanese slaves, though illicit trafficking lingered for some time thereafter.
2 Over 200 Japanese High School Girls Were Used As Nurses In The Battle Of Okinawa
When Allied forces launched the Okinawa invasion in April 1945, the island’s civilian toll skyrocketed, with over 200 000 deaths—including 94 000 Okinawan civilians. Among the casualties were the Himeyuri Student Corps, a group of roughly 200 teenage girls aged 15‑19 forced into nursing duties.
Initially stationed at a military hospital, the girls were later relocated to underground caves as bombing intensified. There, they tended to wounded soldiers, assisted with amputations, and buried the dead. As American troops advanced, the girls were ordered not to surrender and were urged to end their lives with hand‑grenades.
Some obeyed, while others perished amid combat. A tragic episode known as “The Cave of the Virgins” saw 51 girls killed when their shelter was shelled. Post‑war, a monument and museum honor their sacrifice.
1 Japan Had Its Own Nuclear Weapon Program During World War II
The atomic devastation of Hiroshima and Nagasaki in August 1945 shocked the world, yet Japanese physicist Yoshio Nishina had been contemplating such weapons since 1939. He headed Japan’s inaugural nuclear research effort, which began in April 1941.
By 1943, a committee under Nishina concluded that building a bomb was theoretically possible but practically beyond Japan’s wartime capabilities, even for the United States. Nonetheless, research persisted, and a second initiative—the F‑Go Project—was launched under physicist Bunsaku Arakatsu.
Both programs failed to produce a functional device, but historians wonder how differently the war might have unfolded had Japan succeeded. Notably, in May 1945 a German U‑boat carrying 540 kg of uranium oxide destined for Tokyo was intercepted by the U.S. Navy, illustrating how close the nation came to acquiring fissile material.
