Tanabata
七夕
Tanabata is the star festival, one of the old five seasonal festivals. Most of Japan keeps it on 7 July; some places keep it a month later, and Sendai’s runs 6–8 August.
What happens
Tanabata (七夕) was originally one of the five seasonal festivals, held on the seventh day of the seventh month of the lunisolar calendar. After Japan changed calendars, the date came across as it stood, and Tanabata is now most often kept on 7 July.
Not everywhere. Moving the day directly onto the solar calendar also moved it about a month earlier in the season, and some places kept it a month later instead. Sendai is the clearest case: its festival runs 6 to 8 August, and its organisers say they use the calendar one month behind the current one so that the festival falls where the old date used to. Sendai is an example, not the whole of it. Other places keep the later date too, but this archive has not sourced them, so it does not list them.
There is a third reckoning, worth knowing about even though this entry does not carry its dates. The actual lunisolar date is computed each year and has been published since 2001: the seventh day counted from the new moon nearest before the solar term Shosho (処暑). It lands somewhere between 30 July and 30 August and moves every year. If you want to see the sky the festival is about, that is the date to look up; 7 July usually falls before the rainy season has lifted, which is a poor time to look at stars.
So this entry lists two dates a year rather than one, and they are not alternatives to choose between. They are different places doing the same thing a month apart. Which one applies depends on where you are.
Why it matters
What makes Tanabata worth recording carefully is not the festival so much as what happened to its date. It is a festival about looking at the sky, moved by a calendar reform onto a day when the sky is usually not visible. Everything that followed — places keeping it a month later, and an observatory computing the old date and publishing it every year — is people working around that.
It began as one of the five seasonal festivals taken from the older calendar, and it is one of the few places where a reader can see all three reckonings running at once: the solar date, the month-delayed date, and the lunisolar one.
When it happens
Before you go
Japan — national visitor guidance. Not specific to this festival.
Never
- Deface a cultural asset. Graffiti or marks of any kind on temples, shrines and other historic structures cause irreparable damage, and are a criminal offence.
- Take photographs without permission.
- Litter. Use a bin where there is one or carry your rubbish with you, and separate cans, glass and plastic bottles into the right recycling bins.
- Enter private property, including farmland.
- Take large luggage into crowded spaces.
- Ignore posted manner signs. The tourism agency publishes a pictogram set covering locally posted prohibitions — blocking walkways, cutting in line, eating while walking, using a selfie stick, going onto train tracks — and these apply where they are displayed.
Photography
National guidance rather than a rule for any one festival: a responsible traveller does not take photographs without permission, and is asked to be considerate of their surroundings when taking them. Some places post signs prohibiting selfie sticks.
Crowds
Crowds gather at popular places and in peak seasons. The national advice is to plan around them — visit on weekdays, early in the morning or at night — and to avoid sightseeing during commuter rush hours, when local people are travelling to work and school. Using a luggage-storage service, a locker or a courier keeps your hands free in crowded places.
