Time Day

June 10 is Toki no kinenbi, Time Day. The Tokyo Astronomical Observatory and the Seikatsu Kaizen Dōmeikai, a league for improving daily life linked to the Ministry of Education, established it in 1920.

The date comes from the Nihon Shoki. It records that in 671 Emperor Tenji first announced the hours with a water clock, the rōkoku, and with bells and drums. Converted to the solar calendar, that day is June 10. According to one account, the day was created to call on people to keep time strictly and to make daily life more rational.

The Birth of Tardiness

In the late Edo and early Meiji periods, Western visitors to Japan often complained that the Japanese were careless about time. A Dutch naval engineer in Japan at the end of the shogunate was one of them.

The 2001 essay collection Chikoku no tanjō (The Birth of Tardiness) studies how this changed. Most of its essays discuss systems introduced in the Meiji period. A co-organizer of the research writes that time discipline took hold fast in modern institutions such as railways, factories and schools, but spread to the rest of life only after World War II.

Within about 150 years, the old complaint had turned into its opposite.

The School Gate

On July 6, 1990, at Kobe Takatsuka High School, a public school in Hyōgo Prefecture, a male teacher closed the iron school gate at the 8:30 chime as part of lateness control. A first-year girl arriving at that moment was caught by the gate, which weighed about 230 kilograms. She died.

The teacher was dismissed. A court convicted him of professional negligence resulting in death and gave him a suspended sentence.

Delivered on New Year’s Day

Japan Post delivers New Year cards, nengajō, on January 1. For the 2026 New Year, it asked people to post them by Thursday, December 25, 2025, if they wanted the cards to arrive on ganjitsu, New Year’s Day.

The Vocabulary of Set Times

Teikoku (定刻): the set time. The Daijisen dictionary defines it as a decided, fixed time, and gives the example basu wa teikoku ni hassha suru, the bus leaves at the set time.

Nōki (納期): the time for delivering goods or paying taxes, and its deadline. The dictionary’s example is nōki ga semaru, the delivery date is drawing near.

Five Minutes Early

Gofun mae kōdō means acting five minutes early. A first-year newsletter from a Japanese junior high school defines it as gathering at the place of an activity five minutes before it begins. It adds that in the adult world, too, the rule is considered “the key to trust.”

The newsletter also does the arithmetic. When one late person delays the start, the time lost is the delay multiplied by the number of people.

Day-Shift Education

On April 25, 2005, a JR West train derailed on the Fukuchiyama Line, and 107 people died, 106 passengers and the driver. Earlier in the run, the train had overshot its stopping position at Itami Station by about 72 meters and arrived there about one minute and eight seconds late.

JR West had a practice called nikkin kyōiku, day-shift education. After an incident, a crew member could be moved to day duty and retrained. The Kobe Shimbun calls it punitive training. It writes that the investigators’ report suggests that the driver may have been under pressure from the nikkin kyōiku he had been through.
