Tokyo Schools Brace for Record Heat as University Enrollment Shake-Up Looms

At least a dozen public elementary schools in Suginami and Nerima wards cancelled outdoor physical education classes this week after Tokyo Metropolitan Government heat alerts pushed wet-bulb globe temperatures beyond the 31-degree threshold that triggers mandatory activity suspensions. The disruptions, running from Monday through Thursday, affected an estimated 14,000 students across the two wards alone, according to ward education board notices reviewed by The Daily Tokyo.

The timing matters. Japan's Education, Culture, Sports, Science and Technology Ministry — known as MEXT — is simultaneously managing one of the most significant overhauls to university entrance procedures in a decade, with new guidelines on international student enrollment scheduled to take effect for the April 2027 academic year. Schools and universities are juggling administrative deadlines against a summer that is breaking heat records before it has properly begun.

Campuses Feel the Squeeze

At Waseda University's Nishi-Waseda campus in Shinjuku, administrators confirmed this week that summer intensive courses — a key revenue stream for the university's global education division — would shift to hybrid delivery through at least July 18. The decision follows a similar call by Keio University's Mita campus in Minato Ward, where several lecture halls lack adequate cooling capacity for daytime occupancy above roughly 60 percent. Both universities declined to specify how many enrolled students are affected, but Waseda's global education division alone handles more than 6,000 international students per semester.

The heat is compounding pressure on the Tokyo Metropolitan Board of Education, which in late June allocated ¥2.3 billion toward accelerated air-conditioning upgrades for 47 municipal schools still running older cooling systems. That figure, confirmed in the board's supplementary budget passed June 27, is meant to cover installation before the 2027 school year — a timeline some ward officials say is already slipping given contractor availability.

Meanwhile, the MEXT reform attracting the most scrutiny in higher-education circles is a proposed cap on the share of international students that any single department can admit through direct-enrollment tracks, rather than through Japan's Common University Entrance Test. The ministry circulated a draft framework to national university administrators on June 30, setting a departmental ceiling of 20 percent for direct-track foreign enrollment. Critics at several Tokyo institutions argue the ceiling is arbitrary and would disproportionately hurt graduate engineering programs that have relied on overseas recruitment to offset domestic demographic decline.

Numbers Behind the Debate

Japan's 18-year-old population fell below 1.06 million for the first time in 2025, a figure MEXT has repeatedly cited as justification for opening enrollment pathways. Tokyo's universities — there are 140 within the metropolitan area — collectively enrolled approximately 178,000 international students in the 2025 academic year, up from 134,000 in 2022. Inbound tourism's surge has also intensified demand for Japanese-language programs in central areas: enrollment at the Tokyo Japanese Language Education Center in Shinjuku rose 22 percent year-on-year in the spring 2026 semester.

Yen weakness is a complicating variable. With the yen trading near ¥158 to the dollar this week, tuition costs for students paying in foreign currency have effectively dropped relative to two years ago, making Japanese institutions more attractive even as living costs in central wards like Chiyoda and Minato have risen sharply for everyone else. Average monthly rent for a single room within a 15-minute commute of Ochanomizu — a neighborhood dense with universities and prep schools — now sits around ¥95,000, up roughly 12 percent since early 2024.

For families and students navigating the next academic cycle, the practical advice from education counselors this week is to watch the MEXT consultation deadline of August 29, when universities must submit responses to the draft international enrollment framework. Any institution seeking exemptions — particularly those running specialized research programs — needs documented filings before that date. Tokyo Metropolitan Government's education bureau has also advised parents to check their ward's heat-protocol calendar, now updated weekly on each ward's official website, before assuming outdoor school events scheduled for late July will proceed as normal.
