Shigoto-osame / Goyo-osame -- The Last Workday of the Year

What Is Shigoto-osame?

Around December 28th comes shigoto-osame, the last working day of the year. In government offices it is called goyo-osame, where goyo means official duties -- a word held over from the Edo period, when it referred to the business of the authorities. Shigoto-osame is the general term used in the private sector, and because most companies align with the government schedule, the two land on roughly the same date.

Why the 28th? The Answer Goes Back to Meiji

On January 7, 1873, Daijokan Proclamation No. 2, "Establishing Holidays," set official holidays as January 1-3, June 28-30 and December 29-31. The framework of a year-end break running from December 29 to January 3 dates from that moment. Today it is carried on by the Act on Holidays of Administrative Organs (Act No. 91 of 1988), which designates December 29 through January 3 as holidays for government bodies.

• In a normal year: December 28, the day before the break starts, is goyo-osame
• If the 28th is a Saturday: the previous day, December 27, becomes the last working day
• If the 28th is a Sunday: it moves back two days, to December 26
• In 2026: December 28 falls on a Monday, so that is goyo-osame

Banks and the Stock Exchange Work a Little Longer

Government offices may close on the 28th, but the country does not stop. Banks keep their counters open through December 30 (moving earlier if the 30th falls on a weekend), and the Tokyo Stock Exchange's final session of the year, the dainōkai, is normally held on December 30 as well -- a Wednesday in 2026. Those extra days matter if you have year-end transfers or settlements to make.

What "Goyo" Still Carries

Goyo originally meant the official business of the court, the shogunate or a government office. It is the same word behind the constable's cry of "Goyo da!" in period dramas and behind goyokiki, the old term for a shop's order-taking rounds. After the Meiji Restoration it stuck as the word for government work, giving us goyo-osame at the end of the year and goyo-hajime at the start of the next. Goyo-hajime falls on January 4, which in 2027 is a Monday. In the private sector people simply say shigoto-osame and shigoto-hajime; goyo is best understood as an older word that survived around officialdom.

Tips for Marking This Day

• Tidy your desk and your shared folders so that next year's you can find things
• Leave a single handover note covering only what moves in the first week of January
• Look back on the year's work and settle on just one goal for the next
• Thank the colleagues and clients who helped you through the year

A Year-End Break 150 Years Old

The December 29 to January 3 holiday has run largely unchanged since 1873. Late December goes by in a blur, but shigoto-osame is a marker resting on a century and a half of habit. Clear the desk, and cross into the new year with a clean one.
