What religion is practiced in Japan?

Shinto and Buddhism sit side by side in everyday Japanese life, and this guide explains how they overlap, what the numbers mean and how visitors can take part respectfully.

Quick answer: Japan's two main religious traditions are Shinto and Buddhism, and many people take part in both, so the figures often overlap. Small Christian communities, newer religious movements and other faiths also exist. Many people join shrine and temple rituals for seasonal, family or cultural reasons without describing themselves as strongly religious. Survey results differ depending on how each question is worded.

Two main traditions that live side by side

Shinto is Japan's indigenous belief system, and the name means "the way of the kami," the sacred spirits and powers found in nature, places and ancestors. Buddhism arrived from the Asian mainland around the sixth century and grew into several schools, including Zen and Pure Land traditions. For most of Japanese history the two blended closely, and a family might visit a shrine for a festival and a temple for a funeral.

That blending is why a simple religion-in-Japan percent chart can feel confusing. Shinto has no founder, no single scripture and no formal membership, so people rarely say they "are" Shinto in the way someone might say they belong to a church. Instead, a shrine visit is treated as part of life: a custom, a celebration, a way to mark a moment.

There are tens of thousands of Shinto shrines across the country, often estimated at around 80,000 or more, from grand national sites to tiny neighborhood shrines tucked between buildings. Temples are equally common, and many towns have both within walking distance. This everyday presence helps explain why religion in Japan feels woven into daily scenery rather than set apart from it.

How the statistics work and why they overlap

Published numbers come from different kinds of sources. The Agency for Cultural Affairs collects figures from religious organizations themselves, and those totals add up to well over 100 percent because people can be counted by more than one group. In the 2015 figures cited on Wikipedia, Shinto stood at roughly 70 percent, Buddhism at roughly 70 percent and Christianity at about 1.5 percent.

Opinion surveys give a different picture. Pew Research Center figures reported for 2023 on the same Wikipedia page show Buddhism at roughly 46 percent and "no religion" at roughly 42 percent as the largest self-descriptions, and other surveys word the question differently and find different shares. Both pictures are accurate in their own terms: many people do not identify with an organized religion, yet they still visit shrines, join festivals and keep family customs.

What religious life looks like through the year

Everyday practice follows the calendar and the life cycle. New Year visits to a shrine or temple, called hatsumode, are among the most widely observed customs. Summer brings the Obon season, when families remember ancestors, often with Buddhist observances and a visit to the family grave. Local festivals, called matsuri, are usually linked to shrines and community life.

Life events are also marked with religious rituals. Babies are often taken to a shrine soon after birth, children aged three, five and seven are celebrated at Shichi-Go-San, and many young adults mark coming of age. Funerals are largely Buddhist, while weddings may be Shinto, Christian style or non-religious, depending on the couple. Each rite is chosen to suit the occasion rather than to express exclusive belief.

Many homes also keep a small Buddhist altar called a butsudan, where relatives are remembered, and some keep a household shrine shelf for the kami. Visitors staying at a family home or a guesthouse may notice these quiet corners and offerings of rice, tea or flowers.

Other faiths and newer movements

Christianity reached Japan in the sixteenth century, was banned for a long period, and was permitted again in the nineteenth century. Today Christians form a small share of the population, with estimates generally between about one and two percent depending on the source and method. Churches, cathedrals and Christian schools exist in many cities, and Nagasaki is among the places with a notable Christian history.

Japan also has a large number of newer religious movements, many founded since the mid-nineteenth century, some rooted in Buddhist or Shinto teachings. Smaller Muslim, Hindu, Jewish and other communities exist as well, including among residents from overseas. Visitors will find mosques, churches and other places of worship in major cities, though they are far less common than shrines and temples.

How visitors can join in respectfully

Shrines and temples welcome people of any faith or none. The Association of Shinto Shrines notes that there are no specific restrictions on visitors from other religions, and it asks guests to respect the grounds and behave politely. A simple visit might include a bow at the gate, rinsing hands at the water basin and a brief prayer or quiet moment at the main hall.

At shrines, the common routine is two bows, two claps and one more bow, while at temples visitors usually press palms together quietly without clapping. Signs at the entrance or notes from staff will mention any special rules. Photography, entering certain halls and dress expectations can vary by site, so follow posted guidance and take cues from other visitors.

Common misunderstandings

A frequent misunderstanding is that Japan must be either "Buddhist" or "Shinto." In practice, many households follow both traditions at once, and the line between them is not drawn the way it might be elsewhere. Another is assuming that a person who says they have "no religion" has no spiritual life; the phrase often just means no membership in an organized group.

Visitors also sometimes assume that every shrine ritual carries strict religious obligations. For most worshippers, a prayer for health, exams or travel safety is an ordinary courtesy to the kami, not a statement of creed. Treat these places as living sacred spaces: speak quietly, avoid climbing on structures, and do not touch offerings or ritual items unless invited.

Planning your visit and next steps

To see both traditions in one trip, pair a shrine and a temple in the same area, noticing the torii gate at the shrine entrance and the large main gate and incense at a temple. Seasonal events such as New Year, summer festivals and autumn celebrations offer vivid chances to watch community religion in action. Check each site's official page for opening times, rules and events.

For deeper background, encyclopedia entries on Shinto and Buddhism in Japan explain the history in more detail. Local tourist offices can also point to festivals, and they can explain what a visitor may join. Statistics are estimates and change between surveys, so treat any figure as a rough guide rather than a precise count.

Frequently Asked Questions

Do visitors need to be religious to enter a shrine or temple?

No. Shrines and temples are open to people of all backgrounds, and no belief is required to enter the grounds. Visitors are asked to behave respectfully, follow posted rules and observe quietly. Some inner halls or ceremonies may be closed to the public, and signs will usually say so.

Is Shinto a religion or a cultural custom?

Both descriptions are used. Shinto involves shrines, priests and rituals, so it is a religion in the formal sense, yet many people experience it as tradition tied to seasons and family milestones. It has no single founder or scripture, which is why scholars often describe it as a set of practices.

Do most people in Japan follow Buddhism?

It depends on the question. Many families have a Buddhist temple connection and hold funerals in that tradition, and some surveys show Buddhism as the most commonly named religion. Others describe themselves as non-religious while still observing Buddhist and Shinto customs, so no single percentage tells the whole story.
