Most Japanese people describe themselves as non-religious, and most Japanese people also visit a shrine in January and hold a Buddhist funeral when someone dies. Neither statement is a contradiction, because in Japan religion survives less as a set of beliefs than as a set of habits.
Ask a room of Japanese adults whether they belong to a religion, and a clear majority will say no. Surveys have shown this for decades. The Institute of Statistical Mathematics, which has run its "National Character Survey" (日本人の国民性調査, Nihonjin no Kokuminsei Chōsa) every five years since 1953, and the NHK Broadcasting Culture Research Institute have both recorded, over many years, that somewhere between six and seven in ten respondents say they hold no religious faith. By the standard a Western pollster would use — do you believe in a specific God, do you belong to a specific church — most Japanese people opt out.
And yet the same country empties its train stations every New Year as tens of millions make hatsumōde (初詣, the year's first shrine or temple visit), queues at family graves during Obon (お盆, the midsummer festival for ancestral spirits), and holds Buddhist funeral rites for the overwhelming majority of its dead. None of this is treated as unusual, or as a lapse into religion by people who otherwise avoid it. It is simply what a year looks like.
A survey that measures belief, not practice
The gap is not a paradox so much as a mismatch of instruments. Surveys ask about shūkyō (宗教, "religion") as a category — an institution one joins, a creed one affirms. Scholars of Japanese religious life have long pointed out that this question imports a distinction, native to Abrahamic traditions, between religious and secular life that Japan's own history never drew in the same place.
Inoue Nobutaka, professor emeritus at Kokugakuin University's Faculty of Shinto Studies, put it plainly in a recent interview: religious customs in Japan are so woven into ordinary life that most people carrying them out do not register them as religious at all. Roughly seven in ten Japanese visit a grave at Obon or make a New Year shrine visit, he notes, without considering either act "something special." The behavior is common. The label is not. Inoue estimates that some eight in ten Japanese carry what he calls a "faint" or "unconscious" religiosity — present in practice, absent from self-description.
This is also why a single household can, without friction, keep a Shinto kamidana (神棚, a small household altar for Shinto deities) for everyday protection, a Buddhist butsudan (仏壇, a household altar honoring ancestors) for family memory, celebrate Christmas with a cake and lights, and still answer "none" when a survey asks about religion. Each practice is doing a different piece of work — marking a season, honoring a specific ancestor, giving children an event to look forward to — and none of them requires the household to have picked a side.
Religion carried as custom, not creed
Once the frame shifts from belief to practice, the calendar looks less like contradiction and more like continuity. Hatsumōde opens the year at a shrine. Setsubun (節分, the early-February ritual marking the change of season) scatters beans to drive out misfortune. Ohigan (お彼岸, twice-yearly Buddhist observances at the spring and autumn equinoxes) and Obon bring families to ancestral graves. Shichi-Go-San (七五三, a rite of passage for children aged three, five, and seven) takes children to a shrine in formal dress. Christmas, imported in the twentieth century, now sits on the same calendar as a family holiday, displacing nothing older.
None of these observances asks the participant to affirm a doctrine. What they ask for is attendance — showing up at the shrine gate, at the grave, at the family table, at the season's turn. Researchers of Japanese religion often describe this as minzoku shūkyō or folk religious practice: a layer of custom that predates, and now simply coexists with, the formal categories of "Shinto" and "Buddhism" that outside observers reach for first. The two traditions themselves have shared temple grounds and household altars for so long — a fusion historically called shinbutsu-shūgō (神仏習合, the syncretic blending of Shinto and Buddhist practice) — that asking a Japanese household to choose one over the other misreads the situation from the start.
Feeling a place more than believing a claim
If the customs do not ask for belief, what do they ask for? Something closer to attention. Standing at a shrine's inner precinct, under old cedars or beside a sacred rope marking a stone, most visitors are not evaluating a truth claim about a deity's existence. They are registering that the place is different from the street outside it — quieter, ordered, worth a small bow and a coin in the offering box.
This is close to what Shinto has long called kannagara (惟神, living in accordance with the way of the kami): not a set of propositions to accept, but a disposition toward certain places and moments as worth a different kind of attention. A shrine forest, a mountain, an old tree — each can carry the sense of kami (神, spirits or sacred presences associated with natural phenomena and specific places) without any requirement that the visitor hold a settled theological position on what a kami is. The feeling precedes, and often entirely replaces, the doctrine.
A pine tended on shrine grounds in Tokyo. Trees kept within a shrine precinct are cared for as part of the site itself — not worshipped, but treated with the same quiet attention as the shrine buildings around them.
What outsiders find hardest to place
Visitors from societies where religious identity is a fixed, singular category — you are Catholic, or Muslim, or an atheist, and the categories do not overlap — tend to find this the single most disorienting feature of Japanese life. Not the shrines themselves, which read easily enough as tourist sites or historic architecture, but the discovery that the people bowing beside them at New Year would, an hour later, describe themselves on a form as having no religion at all, and mean it sincerely.
The disorientation fades once belief is set aside as the wrong measure. What is actually on display is a culture that has kept its religious customs mostly intact by unhooking them from religious identity — free to be practiced by anyone, revised by no committee, and passed down less as dogma than as the shape of a year.
That same instinct — care and attention paid to a place, a season, or an object without a doctrine attached to justify it — is also what keeps a Japanese garden raked, a tea bowl repaired rather than replaced, and a bonsai tended for a hundred years by owners who never meet one another. Azukari works from the same instinct: a tree stays in Japan, cared for through the seasons by an artist, and its owner joins that rhythm from wherever they live, no belief required beyond the sense that the tree, and the attention it receives, are worth continuing.
For more on the sensibilities behind this kind of attention, see "What Is Ma?" and "Why Japan Avoids Symmetry." Our field letter from the Meiji Jingu Bonsai & Suiseki Exhibition looks at a shrine forest and its bonsai in more detail.
