The Star Crossed Lovers Japan Celebrates Every Summer

Tanabata turns a Chinese star legend into paper wishes on bamboo and streamers over shopping streets, and this guide covers the story, the customs and where to see it.

Quick answer: Tanabata, the Star Festival, celebrates the legend of Orihime, a weaver, and Hikoboshi, a cowherd, two stars separated by the Milky Way who meet once a year. People write wishes on paper strips called tanzaku and hang them on bamboo. It begins on July 7, but many regions celebrate in early August.

The legend of Orihime and Hikoboshi

The story behind Tanabata features two lovers who are also stars. Orihime, a princess who weaves cloth for the heavens, is identified with the star Vega, and Hikoboshi, a cowherd, with the star Altair. The tale says they were so happy together that they neglected their duties, so they were placed on opposite banks of the Milky Way and allowed to meet only once a year.

That meeting is said to fall on the seventh day of the seventh month. In one popular version, magpies form a bridge across the river of stars so the pair can reach each other. If rain falls on the day, it is sometimes described as the lovers' tears, which is why a cloudy or rainy July 7 is a familiar part of the festival's mood. The legend is widely retold in picture books and school lessons.

From a Chinese festival to a Japanese one

Tanabata comes from the Chinese Qixi Festival. Reference works say it arrived in Japan in 755, during the reign of Empress Koken, in a court observance often described as a festival to plead for skill. Courtiers prayed for improved weaving, sewing and handwriting, and the event was linked with a Japanese weaving ceremony tied to Shinto belief.

Over the centuries the festival also took on elements of Obon, the late-summer season of remembering ancestors, and it spread from the court to ordinary people, especially in the Edo period. The result is a celebration that is neither purely Chinese nor purely Japanese. The name itself is written with characters meaning seventh evening, and the common reading, tanabata, is thought to relate to an old weaving custom.

Wishes on paper: tanzaku and bamboo

The best-known custom is writing a wish on a narrow strip of colored paper called a tanzaku and tying it to a branch of bamboo. Traditionally the wishes concerned skills such as penmanship and sewing, and some were written as short poems. Today people write about everything from school exams to health and family happiness, and children often decorate classrooms and kindergartens with their own bamboo.

The bamboo is usually set outdoors or in a doorway, where the paper strips sway in the breeze. When the festival is over, the branches are often floated down a river or burned, in a gesture of sending the wishes on their way. Many shopping centers, train stations and community halls set out a bamboo branch with paper and pens, so visitors can try the custom for themselves. Check local signs for how to join in.

Decorations and what they mean

Beyond tanzaku, Tanabata is known for its decorations. In Sendai, the festival traditionally features seven types of ornaments, each with its own meaning. They include paper cranes for family safety and long life, a purse for business success, a fishing net for a good catch, a paper trash basket for cleanliness and thrift, a paper kimono for good health and sewing skills, and long streamers linked to weaving. The tanzaku is counted among the seven.

Another common ornament is the kusudama, a ball decoration with trailing paper strips that looks something like a giant flower, often hung above the streamers though it is not one of the seven. Each item is typically made of washi, the traditional Japanese paper, and the decorations are often made by hand by local shops, schools and neighborhood groups. Descriptions of the seven ornaments vary slightly between sources, and wording differs from one city to another, so treat the list as a general guide.

Why the dates differ by region

July 7 is the starting point on the modern calendar, but Tanabata is held on different days across Japan. The old festival followed the lunar calendar, and the seventh day of the seventh lunar month falls in August on the modern calendar. Many places therefore celebrate on or around August 7, a pattern often called the one-month delay, while others stay with July 7.

Early July often falls within the rainy season in much of Japan, which is one reason the later August date appeals to some places. For a visitor, this means there are several chances to catch a Tanabata event between early July and mid-August. Exact dates change from place to place, so check each festival's official site or the local tourist office before booking travel.

Famous Tanabata festivals

Sendai's Tanabata Matsuri is the best-known regional version, held each year from August 6 to 8, with a fireworks show the evening before. Streamers of washi hang from the roofs of covered shopping arcades, and local people often wear yukata. Tourism material describes the decorations in Sendai as especially elaborate, and they are often put up earlier than the festival itself.

In the Kanto region, Hiratsuka in Kanagawa Prefecture holds one of the largest festivals around July 7, and the Asagaya neighborhood of Tokyo holds a well-known event shortly before the mid-August Obon holidays. Many smaller towns, temples and shopping streets also have their own events, usually with food stalls and displays. Dates and details can change, so verify the current program before visiting.

Joining in as a visitor

Tanabata is easy to enjoy because the main activity is simple. Visitors can write a wish on a tanzaku wherever a bamboo is provided, then tie it up at a spot that is clearly set aside for that purpose. Short, positive wishes are common, and writing in English is generally fine. Pens are often provided, but it helps to bring a favorite just in case.

Other tips are practical. Festival streets can be crowded in the evening, so going earlier in the day often means a calmer look at the decorations. Wearing a yukata is popular but never required. Weather can change quickly in summer, so a small umbrella and water are useful. Bamboo and decorations at public events belong to the organizers, so avoid taking them home as souvenirs.

Frequently Asked Questions

When is Tanabata celebrated?

Tanabata starts on July 7, but the date varies by region. Many places celebrate in early August, often around August 7, because the old festival followed the lunar calendar. Sendai's famous event runs from August 6 to 8. Because schedules differ and can change, check the local organizers' current information before traveling.

What do people write on tanzaku?

People write personal wishes on the narrow paper strips. Traditionally the wishes were about skills such as calligraphy, sewing and weaving, and some were written as poems. Today they cover a wide range of hopes, including health, school, work and family. Short, positive wishes are typical, and they are hung on bamboo for the duration of the festival.

Which stars are Orihime and Hikoboshi?

Orihime is associated with Vega and Hikoboshi with Altair, two bright stars of summer that appear on opposite sides of the Milky Way. In the legend, the river of stars separates them. On a clear night, the Milky Way is easiest to see away from city lights, so rural areas and mountain towns are the best places to look.
