Japan's Temples Fight for Survival as Population Decline Threatens Religious Heritage

On the Chita Peninsula in central Japan, a 370-year-old temple with a curved roof, timber-frame walls, and an elaborately decorated altar sits in manicured gardens waiting for a buyer. The asking price is 482 million yen—roughly 2.66 million euros. The estate agent's listing includes something unusual: expert heritage craftsmen will dismantle the entire structure and deliver it anywhere in Japan, where it will be painstakingly restored into a two- or three-bedroom home. The sale marks the end of this temple's role in the local community, but it represents a gentler fate than what many other temples across Japan are experiencing.

Japan has approximately 77,000 temples scattered across the country. As many as 17,000 of them no longer have a full-time resident priest. The cause is straightforward: congregations have shrunk, particularly in rural areas experiencing rapid depopulation, and the financial pressures have become unsustainable. The result is a slow-motion crisis. Temples are being sold off. Others are simply shuttered and left to decay, their roofs gradually failing, their grounds overtaken by weeds, their purpose forgotten by the communities they once served.

Tomomi Iwayama took over the abandoned Ganshu-ji temple in Odawara, a coastal town about 80 kilometers southwest of Tokyo, a decade ago. When he arrived, the temple had been without an abbot for 70 years. The building still stood, but it had become economically unviable—too expensive to maintain, too few worshippers to support it. Iwayama has spent the past ten years rebuilding. He has worked to reconnect with the local community, sold plots in the temple graveyard, and introduced innovations like a "smart graveyard" where families use a card to trigger a robotic system that retrieves a relative's ashes from storage. Today, the congregation is growing. But even in Odawara, a city of 200,000 people, the work has been grueling. In the countryside, Iwayama says, it is far worse.

The core problem is Japan's shrinking population. Young people leave villages to attend university in the cities and rarely return. They might visit once a year to pay respects at the ancestral temple, but that single visit cannot sustain a temple's operations. When the head priest of a rural temple retires, his children are unlikely to take on the role. The challenges are simply too great. The result, more often than not, is closure.

Yet Iwayama resists the comparison to religious decline in the West, where Christian congregations have collapsed over decades. He argues that demand for Buddhism remains robust in Japan, even as the traditional revenue streams—funerals, memorial rites, anniversary ceremonies—have begun to dry up. People living fast-paced, technology-saturated lives are seeking something different, he suggests. They are drawn to Buddhism as a philosophy, a way of living. Temples that have adapted are finding success by offering meditation classes, traditional cooking courses, and other experiences that align with what modern Japan is seeking. Temples that cannot make this shift are at risk of disappearing.

Jake Adelstein, an American journalist and author, is now a Zen priest at Zenshoin Temple in Tokyo and is training to become an abbot. He pushes back against the idea that Japanese people are becoming less religious. Rather, he argues, they are becoming fewer due to population decline and less wealthy due to economic pressures. Families want to maintain grave plots they have held for generations, but the annual fees—up to 100,000 yen—combined with the cost of memorials and other rites, have become prohibitively expensive. Many families live far from their ancestral temples and cannot visit regularly to maintain the graves. Young people, meanwhile, have little incentive to pursue careers as priests. Temple salaries are low. The work is demanding. The economics rarely work out. Some temples have begun sharing priests to reduce costs, but Adelstein acknowledges this solution will become increasingly difficult to sustain.

At Zenshoin Temple, Adelstein and his colleagues have launched vegetarian cooking classes and meditation sessions to build community ties and generate revenue. He views the temple as critical to Japanese society and culture, even as he recognizes the brutal economics of the situation. The training to become an abbot is rigorous. The financial model is fragile. Yet he continues the work, aware that without adaptation and without people willing to take on these roles, Japan's temples—structures that have stood for centuries, repositories of art and philosophy and collective memory—will continue to vanish from the landscape.
