Why Japan's Business Year Starts in April, Not January
A 19th-century cash crunch forced Japan to shorten its fiscal year and move the start to April. The fix outlived the crisis, and now governs hiring, school terms and earnings season for the world's fourth-largest economy.
File a project report in Tokyo for work done last January, and a Japanese colleague will describe it as happening in a different fiscal year than a report on the same month filed in Seoul, New York or London. Not because anyone made an error. Japan's fiscal year runs from April 1 to March 31, so the January just past still belongs to the fiscal year that started the previous April. Every company earnings report, government budget line and school term in the country runs on that same offset calendar — and the reason traces back to a cash crunch in the 1880s, not a modern conviction that spring is a better place to start counting.
A shortened year, on purpose
Japan's fiscal year used to start in July. In 1884, the Meiji government, pouring money into rapid Westernization and a military buildup, ran short of tax revenue and began drawing on the following year's budget just to cover its bills. To stop the shortfall from compounding, officials moved the fiscal year's start from July to April in 1886 — which meant the 1885 fiscal year lasted only nine months instead of twelve. Shrinking the year on paper shrank the window the government had to spend money it didn't have, and the crisis eased. April start stuck as the default.
A second explanation, not mutually exclusive, ties the date to the old land-tax calendar: under the Edo-era system, rice was harvested in autumn, sold for cash over the winter, and taxes were settled once that revenue came in — leaving spring as the natural moment to open a new set of books.
The date that now runs the whole country at once
Once the treasury moved, everything downstream followed. Japan's Elementary School Law formalized an April academic start by 1900, and it now governs universities too — meaning the country's school year and its business year turn over in the same week. Companies fell in line for a practical reason: recruiting is far simpler when new graduates walk straight from a March commencement into an April desk. Job-hunting season runs from roughly November to February so that offers are locked in well before graduation, and on April 1 itself, employers across the country hold entrance ceremonies on the same morning.
The scale of that synchronized start shows up in the numbers. At its April 2024 ceremony, the ANA Group inducted 2,848 new employees at a Haneda Airport hangar; convenience-store chain Lawson brought in 107; Daiwa Securities welcomed 486. One new hire at insurer Sompo Japan captured the mood most new employees share walking in that morning: "Although I felt somewhat anxious about the consecutive incidents of misconduct, I've come to take it personally. It's important for me to sincerely engage with each customer as I step into society."
Why it still trips up outsiders
The offset keeps creating friction for anyone doing business across the border. A Japanese company's "first quarter" runs April through June, not January through March — so a foreign investor skimming a headline about "Q1 results" from a Tokyo-listed firm is reading about a period that ended in June, three months after their own Q1 closed. Corporate earnings season lands in a correspondingly different window too: results for the fiscal year that just ended in March get finalized and released in late April and early May, which is also why Japanese stationery shops stock diaries and planners that begin in April instead of January — an entire consumer product category built around a 19th-century budget fix. The tax shortfall that forced Tokyo's hand a century and a half ago is long resolved. The calendar it left behind still sets the rhythm of how tens of millions of people start their jobs, close their books and turn the page each spring.
