As Eita Sato and Aoi Hoshi walked towards their junior high school graduation ceremony, their footsteps echoed in polished halls once crowded and noisy with students.

The two were the only graduates of Yumoto Junior High in a mountainous part of northern Japan - and the last. The 76-year-old school will shut its doors for good when the school year ends on Friday.

“We heard rumours about the school closure in our second year, but I didn’t imagine it would actually happen. I was shocked,” Eita, who like Aoi is 15, said.

As Japan’s birthrate plunges faster than expected, school closures have picked up pace especially in rural areas like Ten-ei, a mountainous skiing and hotspring area in Fukushima prefecture, dealing a further blow to regions already struggling with depopulation.

Falling births are an Asian regional issue, with the costs of raising children dampening birthrates in neighbouring South Korea and China. But Japan’s situation is especially critical.

Prime Minister Fumio Kishida has pledged “unprecedented measures” to boost the birthrate, including doubling the budget for child-related policies, and says maintaining the educational environment is crucial.

But little has helped so far.

Births tumbled below 800,000 in 2022, a new record low, according to government estimates and eight years earlier than expected, dealing a knockout blow to smaller public schools that are often the heart of rural towns and villages.

About 450 close every year, government data shows. Between 2002 and 2020, nearly 9,000 shut their doors forever, making it hard for remote areas to lure in new and younger residents.

“I’m worried that people won’t consider this area as a place to relocate to start a family if there is no junior high school,” said Eita's mother Masumi, also a Yumoto graduate.

Fighting gives way to friendship

Ten-ei, a village of just under 5,000 residents with only around 10% under the age of 18, is in a quiet rural area known for its rice and sake. The Yumoto area has hot spring inns on the mountains and is dotted with ski rental shops and campsites. There are also “beware of bears” signs.

The village at its peak in the 1950s had more than 10,000 residents, supported by agriculture and manufacturing. But the area’s growing inconvenience and remoteness prompted residents to leave.

Depopulation picked up speed after the March 11, 2011 disaster at the Fukushima Dai-ichi nuclear plant less than 100 km (62 miles) away, with Ten-ei suffering some radioactive contamination that has since been cleaned up.

The Yumoto school, a two-storey building located in the centre of the district, had some 50 graduates a year during its heydey in the 1960s.

Photos of each graduating class hang near the entrance, going from black and white to colour - with the number of students visibly and suddenly dropping from around 2000.

There is no picture from the last year.

Eita and Aoi, together since three, were in a five-person class through elementary school but were the only two to go on at Yumoto.

Their desks sat side-by-side in the centre of a classroom designed for 20, and during their first year they “fought a lot”, Eita said.

But tensions eased and they adapted, trying to simulate a normal school experience. For the afterschool club activity that is a key part of Japanese schooling they selected pair sports, mainly table tennis.

On graduation day, teachers pinned corsages on the laughing graduates, usually a job for younger students.

“People are very disappointed there’s no longer a source of culture,” said principal Mikio Watanabe of the decision to close, taken in consultation with village residents. “The place will be quieter without children’s voices.”

Experts warn that rural school closings will widen national disparities and put remote areas under more pressure.

“The school closure means the municipality will eventually become unsustainable,” said Touko Shirakawa, a sociology lecturer at Sagami Women’s University.

Ten-ei will discuss repurposing the school building. In other parts of Japan, closed schools have become wineries or art museums.

Aoi, who dreams of being a nursery school teacher in her hometown, will attend a different school from Eita starting in April.

“I don’t know if there will be any children in the village when I am a teacher,” Aoi said. “But if there are, I want to come back.”
