A Star of Festivals
Summer is the season of vibrant festivals in Japan, when residents and visitors celebrate myths, history and culture with decorations, parades, dances, fireworks and more. One popular summer festivity is Tanabata on July 7, a celebration of love and aspiration, when rainbow-coloured streamers flutter high above streets and homes, and displays of bamboo branches are laden with multicoloured papers, each holding the written, secret wishes of hopefuls.
Whether you're visiting Japan, attending a local event, or simply want to mark the occasion at home, this guide covers everything you need to know about Tanabata 2026.

The Legend Behind the Star Festival
Known as the Star Festival, Tanabata was born from a legend of celestial, romantic drama. At its heart is a poetic tale of star-crossed lovers — Orihime, a princess who wove garments for the gods, represented by the star Vega, and Hikoboshi a cowherd of the heavens, represented by Altair. Their love was all-consuming, so much so the couple began to neglect their celestial duties. Orihime stopped weaving and Hikoboshi’s cows wandered aimlessly across the heavens.
To restore order, Tentei, the Sky King and Orihime’s father, decided the lovers had to be separated and banished them to opposite sides of the Milky Way — an uncrossable celestial river. On seeing his daughter's despair and sorrow, however, Tentei was so moved, he finally agreed to allow the two to reunite, but just once a year. The seventh day of the seventh month — Tanabata — is the day that Orihime and Hikoboshi eternally pine for, the only day they can be together.
What makes this mythology compelling is the astronomy behind it. Vega and Altair are two of the brightest stars in the summer sky and genuinely do appear to sit on opposite sides of the Milky Way — Altair sits 17 light-years from Earth, and Vega 25 light-years away, placing the two lovers on entirely different celestial shores. Every July, stargazers can look up and see the star-crossed lovers themselves.

From Imperial Court to the Streets
Tanabata was introduced to Japan from China by Empress Koken during the Nara period (710–794). It began as a courtly event that later merged with Japanese traditions like the summer Obon festival that honours ancestors. By the Heian period (794–1185), Tanabata was a time to reflect on love and longing, marked by Japanese nobility with poetry writing and wish-making under starlit skies.
Some took their wishes to an artful extreme. Prayers were written on mulberry paper using ink mixed with dew collected from taro leaves at dawn with the belief the magical concoction would make their wishes more potent. It wasn’t until the Edo period (1603–1867), when the festival became popular among the general public and people began writing desires and hopes on tanzaku votive slips, colourful strips of paper that were hung on bamboo branches as prayers to the gods.
By the Meiji Era, the festival had been adapted to the Gregorian calendar, assigning Tanabata on 7 July. Some regions, particularly in northern Japan, still celebrate according to the original lunar calendar, holding festivities in August instead.
How Tanabata is Celebrated Today
Today, Tanabata is celebrated across Japan with surprising regional variety. Here are some of the most distinctive traditions:
Sendai, Miyagi hosts Japan's most famous Tanabata festival, held each year on 6–8 August. The city's covered shopping arcades are transformed by over 3,000 handmade fukinagashi streamers crafted from washi paper, silk and crepe in every imaginable colour, some hanging several metres in length. Around 2 million visitors travel to Sendai for this event each year, and a spectacular fireworks display on the evening of 5 August marks the official start of festivities.
Tokyo and most of Japan celebrate on 7 July, with neighbourhoods, shopping streets and railway stations adorned with bamboo displays and colourful tanzaku wishes.
Hiratsuka, Kanagawa — running 3–5 July 2026 — is considered one of Japan's largest Tanabata festivals, drawing enormous crowds with its elaborate street decorations, lit-up streamers in the evening and lively food stalls.
Anime and popular culture have also kept Tanabata thriving in younger generations. The festival appears in countless popular series — from "Naruto" to "Sailor Moon" to ""Your Name (Kimi no Na wa) — making it one of the most culturally recognisable Japanese celebrations worldwide.
What Do the Tanzaku Colours Mean?
The tanzaku coloured strips of paper hung on bamboo branches aren't chosen at random. Rooted in the Chinese philosophy of the Five Elements, each colour carries a specific meaning:
Green/Blue: Nature, courtesy and self-improvement CORRECTION 4
Red/Pink: Gratitude to ancestors and parents
Yellow: Friendship and interpersonal relationships
White: Sincerity, integrity and duty
Purple: Wisdom, academic success and career (traditionally black, but purple is used in Japan as black is considered unlucky)
Most Tanabata displays use all five colours together, creating the vivid, festive cascades of paper that we see today.
Celebrating Tanabata at Home
You don't need to be in Japan to mark the Star Festival. Here's how to bring Tanabata into your home this July:
-
Set up a bamboo branch display. A single branch of bamboo or even a flowering sprig from the garden works beautifully as a display. Stand it in a vase or pot of earth ready for you to hang your tanzaku from the branches.
-
Write your wishes on tanzaku slips. Use strips of coloured paper — roughly A6 in length works well. Write one wish per strip, fold the top and thread it with string for hanging.
-
Choose your paper colours with intention. Pick colours that match what you're wishing for — see the guide above — though it's also fine to use all five for a vivid, traditional display.
-
Use quality paper and a good pen. Japanese calligraphy brushes or fine ink pens make the wish-writing itself feel like a mindful ritual.
-
Look up at the night sky. If the weather allows, step outside on the evening of 7 July and find Vega and Altair — the two lovers — on either side of the Milky Way. It's surprisingly moving.
-
Make it a family moment. Tanabata is a wonderful celebration to share with children. Encourage them to write their own wishes; there's no wrong answer, and the tradition of articulating hopes and dreams aloud (or in writing) has real value beyond the mythology.
