The blood-soaked meaning behind the mysterious marks on the floor at Tokyo Station【Photos】
Casey Baseel Aug 9, 2021- Tweet

Almost nobody notices them, but they’re reminders of a violent era in Japan’s past.
From the moment you set foot inside Tokyo Station, you’ll see that it’s full of travelers, train lines, and souvenir shops. But what might not be so obvious is that it’s also full of secrets.
Well, we suppose you could argue that they’re not secrets so much as things almost nobody notices, despite their deep significance. That’s not to say that people are inattentive, though. The first one we’re looking at today, for example, is hiding in plain sight near the ticket vending machines right outside the gates at the station’s Marunouchi South Entrance.
▼ Can you see it?
Inlaid in the floor tiles is an unusual symbol, with a white hexagon inside a black circle. Most people don’t even realize it’s there, and those that do probably figure it’s some sort of marking for maintenance workers. Who it’s really of interest to, though, is historians, because the symbol marks the exact spot where one of Japan’s most shocking political assassinations took place.
The first half of the 20th century was an especially volatile time in Japanese politics, as industrialists and military leaders jockeyed to fill the power gap caused by the dismantling of the shogunate at the end of the Meiji Restoration. With Japan’s isolationist policy revoked and the common people removed from their status as subservient peasants, there was intense debate as to what direction the country should take in this new, wide-open era, and plotting a course that would please everyone was an impossible task for any politician, including Prime Minister Hara Takashi, who took office in 1918.
When Hara was at Tokyo Station on November 4, 1921 to board a train for Kyoto, a rail worker with right-wing political affiliations chose to express his disapproval for Hara’s conduct, with his belief that the prime minister was in the pocket of business conglomerates and his distaste for the politician’s push for universal suffrage among his grievances. He chose to communicate his displeasure by stabbing Hara with a knife in the right side of his chest, killing him almost instantly.
Moving on to the area inside Tokyo Station’s regular ticket gates, if you head towards the gates for the Shinkansen using the building’s Central Passage you’ll come to a short flight of stairs.
Once again, if you look down you’ll see a marking on the floor. This one is larger, making it look even more like some sort of maintenance hatch, maybe one designed by ninja taking a page from the Pokémon manhole cover playbook by decorating it with a throwing star pattern.
Actually, though, this is another place in Tokyo Station where someone wanted to kill the prime minister of Japan. This time the target was Hamaguchi Osachi, who began his term in 1929. Hamaguchi was also attacked by a right-wing assassin, following anger from the political faction over his unsuccessful economic policies and attempts to limit military expansionism.
Despite the shuriken-like motif on the floor marking, the assassin used a pistol, shooting Hamaguchi on November 14, 1930, while he was at Tokyo Station to board a train for Okayama Prefecture. A doctor was able to perform first aid and Hamaguchi was rushed to the hospital of Tokyo Imperial University (the present-day University of Tokyo) where an emergency surgery kept him alive, but he never fully recovered and died from lingering complications related to his injury the following year.
Both memorial markers are accompanied by Japanese-language plaques on the wall explaining their meanings, but their nondescript appearance means that few, if any, of the people hurrying to their train register that the signs are there, let alone stop to read them.

For those that do understand their significance, though, they’re a reminder of just how much history Tokyo Station has, and how fortunate Tokyoites are to be living in a much more stable society than their counterparts from less than a hundred years ago.
Meanwhile, if you like your Japanese rail secrets a little less blood-soaked, there’s always the Tokyo train station with the hidden kitty cats.
