Tanabata: Japan’s Star Festival, Wish-Writing Tradition, and Regional Celebrations
Tanabata — the “Star Festival” — is celebrated on July 7 in most of Japan (August 7 in some regions following the old lunar calendar), commemorating the annual meeting of the stellar deities Orihime (the weaver star, Vega) and Hikoboshi (the cowherd star, Altair), separated for the rest of the year by the Milky Way. The festival’s defining custom is writing wishes or poetry on small strips of colored paper (tanzaku) and hanging them on bamboo branches alongside other traditional decorations — a practice combining the star legend, agricultural harvest prayer, and the deeply Japanese aesthetic of hoping and waiting expressed in seasonal ritual.
The Legend of Orihime and Hikoboshi
The legend derives from a Chinese tale introduced to Japan during the Nara period (8th century). Orihime, daughter of the Sky King (Tentei), wove cloth on the bank of the Amanogawa (Milky Way) until she fell in love with Hikoboshi, a cowherd on the other bank. So absorbed in their love, both neglected their duties; the Sky King separated them to the opposite shores of the Milky Way, permitting their meeting only on the seventh night of the seventh month — provided the sky is clear. If rain or clouds obscure the sky, the meeting is delayed until the following year. The legend’s combination of separated lovers, the visible Milky Way on a clear July night, and the conditional reunion depending on weather gives Tanabata a melancholy beauty that resonates with the Japanese aesthetic sensitivity to transience.
Tanzaku: Writing Wishes
Writing wishes on tanzaku (5cm × 30cm strips of colored paper) and tying them to bamboo is the festival’s central participatory practice. The color of the tanzaku traditionally corresponds to the five Chinese elements: blue/green (wood), red (fire), yellow (earth), white (metal), black/purple (water). Wishes were originally written in the categories corresponding to each color — academic improvement (gold), improvement at work (blue), love wishes (pink/red) — though the color-coding is rarely observed strictly in contemporary practice. Bamboo branches decorated with tanzaku and other paper decorations are displayed outdoors, in homes, schools, and shopping centers throughout July.
Major Tanabata Festivals
Sendai Tanabata (August 6–8): The largest Tanabata festival in Japan, held in Sendai according to the old calendar. The city’s main shopping arcades are transformed by enormous hanging decorations (kazari) — massive streamers of paper and bamboo in traditional forms (cranes, nets, paper strips) extending 5–10 meters from shop awnings. The scale and craftsmanship of Sendai’s decorations are unmatched anywhere in Japan; the festival draws over 2 million visitors annually. A preliminary fireworks display on August 5 opens the festivities.
Hiratsuka Tanabata (Kanagawa, July 7–9): The largest July 7 Tanabata celebration in the Kanto region, held in the city of Hiratsuka south of Tokyo. The shopping district is decorated with handmade streamers; food stalls and entertainment events accompany the decoration display.
Asagaya Tanabata (Tokyo, early August): The Asagaya neighborhood’s Pearl Center covered shopping arcade in western Tokyo hosts a charming neighborhood Tanabata with handmade decorations made by local shopkeepers and schools — a smaller-scale but highly authentic event.
Tanabata in Daily Life
Tanabata’s wish-writing custom extends beyond the major festivals into schools, kindergartens, and public spaces throughout Japan. Large bamboo branches set up at train stations, shopping malls, and hospitals invite passersby to write wishes and add them to the display; the resulting collection of hundreds of small colored strips — wishes for passing examinations, recovering health, meeting again with distant loved ones — creates a moving public expression of private hopes. For visitors, writing a tanzaku wish in whatever language is natural and hanging it on a public bamboo is a simple, genuine participation in one of Japan’s most human seasonal customs.
