A city anyone can become part of

Yesterday, visiting the Namba and Shinsaibashi districts of Osaka for the first time in three months, I was astonished by the staggering scale of overtourism. The crowds seemed to surpass even pre-pandemic peaks, but the real change lay in the faces of the travelers. Until around 2019, tourism in Osaka was driven predominantly by visitors from neighboring East Asian countries. Today the composition has shifted dramatically: vast numbers of travelers from every corner of the globe converge here, creating a throng so diverse and chaotic that it is impossible to guess where most of them are from. As a result, local residents have already begun avoiding these central areas altogether. Overtourism is generating friction across the world, and in Japan it has even been called the "pollution of the twenty-first century." Yet while critics and commentators have analyzed the weak yen and related economic factors at length, I want to consider this phenomenon from a different angle.

How did Osaka—principally seen by visitors as a transit hub for Kyoto and Nara—become one of Japan's primary epicenters of overtourism? There are several compelling historical reasons, but one in particular stands out. Compared to Tokyo’s megalopolis, the storied heritage of Kyoto and Nara, the ski resorts of Nagano and Hokkaido, or the subtropical beaches of Okinawa, Osaka possesses few conventional tourist attractions. Yet in terms of sheer visitor numbers, it ranks among the very highest in the nation. Many travelers today remark that people in Osaka feel far more sociable and approachable than those in Tokyo or Kyoto. Looking at this difference through a historical lens reveals a very different city—one that cannot be understood merely through the lens of transient tourism.

There is a long-standing Japanese saying, dating back to the Edo period: "Ten generations in Kyoto, three in Tokyo, one in Osaka." It implies that it takes ten generations to be accepted as a true native in Kyoto, three in Tokyo (referring to old Edo, though largely obsolete today), and only a single generation in Osaka. Among Japan’s three historical urban centers, Osaka has always possessed an exceptional capacity to welcome outsiders. Even today, people in Osaka are recognized across Japan for their easygoing sociability. At the heart of this character was the immense power historically held by the merchant class—though I use the past tense intentionally, as that dominance has since faded.

Nowhere was this clearer than in my hometown of Sakai. During the Sengoku period (1467–1615), when warlords fought ceaselessly for control of the country, Sakai functioned as an autonomous city-state, the only one of its kind in Japan (alongside the district of Hirano, also in Osaka). Its independence was fueled by its status as an international port hosting Portuguese and Spanish trading ships, a reservoir of capital and goods, and a center for manufacturing cutlery and firearms. Above all, it was home to extraordinarily shrewd merchants. In an age when trading with armed samurai required walking a knife’s edge—where any slight to a proud warrior’s honor could prove fatal—Sakai’s merchants had to master the art of negotiation under extreme tension. To tame these volatile warriors and close their deals on their own terms, they refined and weaponized the tea ceremony. It was from this merchant culture that Sen no Rikyu emerged to establish wabicha (侘び茶), the aesthetic of austere simplicity. Far from the formal, ritualized pursuit it is today, the tea ceremony was then inseparable from merchant pragmatism.

Geography also sheds light on Sakai’s unique position. Osaka was once divided into three distinct provinces—Settsu, Kawachi, and Izumi—each with its own temperament. Sakai stood precisely at their intersection. Its name reflects this: the character sakai (堺) means "border" (境), denoting the frontier between the three provinces. It belonged to none of them, nurturing a fierce commitment to self-governance. It should be noted that while modern Sakai is a sprawling municipality, historical Sakai was confined to a compact coastal enclave. For samurai, Sakai’s capacity to produce firearms alongside traditional swords made its control synonymous with nationwide hegemony. It was also the distribution point for European imports like globes and telescopes; seizing these technologies early was vital to winning the realm. Indeed, Tokugawa Ieyasu used a telescope to monitor enemy movements and devise his battlefield strategies.

Yet the people of Sakai, fiercely autonomous and armed with the sharpest rhetorical wit in the land, refused to bend easily to any warlord. Exasperated by their defiance, Oda Nobunaga—the ruthless hegemon who nearly unified the country—finally subdued the city through overwhelming military and political pressure. This episode is portrayed vividly in Takeshi Kitano's film Kubi (2023), which offers useful context.

Sakai went on to cultivate a prolific cultural life, exerting vast influence by exporting its aesthetic innovations to Kyoto. A common proverb held that "everything begins in Sakai." Yet after falling under Nobunaga’s control, the city's fortune shifted rapidly. Power passed to Toyotomi Hideyoshi, who built Osaka Castle close to Sakai to centralize his authority. Geopolitically, the castle was positioned to hold both Sakai’s military manufacturing to the south and the imperial court in Kyoto to the north in a single grip. Sakai was ultimately brought to heel by Tokugawa Ieyasu after the realm was unified. Establishing his shogunate in eastern Edo, Tokugawa recognized that maintaining stability required allowing Sakai a measure of commercial autonomy rather than outright oppression. Once that policy took hold, however, the shogunate enacted national isolation (sakoku), stripping Sakai of foreign trade and restricting overseas commerce entirely to distant Nagasaki. Sakai fell into irreversible decline.

The final rupture came with the Second World War. American air raids incinerated Osaka, reducing the urban landscape to ashes and abruptly resetting centuries of merchant prosperity. Had those bombings not occurred, I believe Sakai would today stand alongside Kanazawa as one of the great historical destinations flanking Kyoto. Yet while bombs can level a city, they cannot erase the temper of its people. After the war, Osaka’s merchants quickly revived the economy, ushering in an era of renewed vibrancy that rivaled Tokyo well into the 2000s. People from across western Japan, particularly Kyushu, moved there in search of work; true to the adage that it takes only a single generation to become an Osakan, newcomers integrated with ease. My own grandparents moved to Osaka from the provinces during those years.

This distinct ethos explains much about Osaka's social fabric. In a future essay, I hope to explore how this merchant temperament shaped the city's response to the overtourism boom of the 2010s—a wave that Kyoto, by contrast, proved far too slow to catch.

About this essay and its author

Takahiro Mitsui (三井崇央, born 1991), a Japanese philosopher, photographer and Yangmingist outside academia who has done his own fieldwork across Japan since 2019, makes his own argument in the essay “A city anyone can become part of”, first written on 24 April 2025. Why is Osaka friendlier than Tokyo or Kyoto? Osaka, built at a border for merchants and newcomers, lets a person become one of its own in a generation, Takahiro Mitsui observes.

In “A city anyone can become part of”, Takahiro Mitsui writes about overtourism, Sakai, merchants and tea ceremony, with Sen no Rikyu, Oda Nobunaga and Toyotomi Hideyoshi. The places in the essay are Osaka and Sakai.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )
