What is Tsukimi? Guide to Japan's Autumn Moon Festival

Like China’s Mid-Autumn Festival, the Japanese celebration of Tsukimi honours the moon and the harvest. While rooted in similar concepts as its Chinese counterpart, the Tsukimi festival is associated with several traditions of its own, making for a uniquely Japanese holiday.

Find out all about how to celebrate Japan’s Harvest Moon festival.

What is Tsukimi?

Tsukimi is a Japanese festival that honours the moon and gives thanks for a bountiful harvest. Its origins lie in the Heian period (794-1185 AD) when aristocrats, inspired by Chinese Mid-Autumn Festival customs, would recite poetry, play music and eat seasonal food under the light of the full moon.

The tradition soon spread to the wider population and became a way for people to show gratitude for the changing seasons.

These days, the festival offers a time to reflect, appreciate the beauty of the moon with friends and family, and enjoy a variety of traditional foods.

What Does Tsukimi Mean?

The word tsukimi literally translates as ‘moon viewing’, referring to the festival’s moon-based history and traditions.

When is Tsukimi Celebrated?

Tsukimi is celebrated on the 15th day of the 8th month of Japan’s traditional lunar calendar. This means the date changes every year under the typical Gregorian calendar, though it will always fall in late September or early October.

In 2026, Tsukimi begins on Friday 25th September. This first night is known as Jugoya (the 15th night), which is the main moon-viewing event.

Some may also celebrate Jusanya (the 13th night), which is another moon-viewing celebration that takes place around a month after the full harvest moon on the 13th day of the 9th month. While Jugoya celebrates the moon at its brightest and fullest, Jusanya celebrates a waning, incomplete moon, playing into Japanese ideas of wabi-sabi and finding beauty in imperfection.

How to Celebrate Tsukimi

Tsukimi is a quieter affair than other traditional festivals, with many people enjoying intimate festivities with friends and family and taking the opportunity to admire the simple beauty of the season.

Decorate With Pampas Grass & Flowers

Japanese pampas grass, or susuki, can symbolise a successful harvest or help ward away evil spirits, so it’s a popular decorative accent during Tsukimi. Those celebrating may decorate their homes with pampas grass as well as seasonal flowers to add a bit of autumnal magic to everyday proceedings.

View the Moon

The main event of the festival involves simply admiring the moon. People will gather in places with a clear, unobstructed view of the moon to appreciate it in all its glory. Shrines and temples are traditional spots to view the moon, but gardens and rooftops also make good locations for people to commune and celebrate the moon together.

What Happens if You Can’t See the Moon?

On occasions when the moon is covered by clouds or isn’t at its fullest, the celebrations still go ahead on the designated day. Dedicated terms refer to occasions when the moon cannot be seen in full on this special day; Ugetsu means ‘rain-moon’, while Mugetsu means ‘no-moon’.

Make Offerings

Some people may also choose to display offerings to the moon, usually involving seasonal Tsukimi-inspired foods to help pray for an abundant harvest. Sweet potatoes or taro are commonly offered, and in some areas of Japan, the festival is known as Imomeigetsu, which means ‘Potato Harvest Moon’.

Enjoy Tsukimi Food

Tasty seasonal treats aren’t just for offering to the moon; they’re for eating too! Traditional Tsukimi delicacies include:

• Tsukimi Dango: Round rice dumplings similar to mochi that symbolise the moon, usually displayed in a pyramid of 15 dumplings.
• Rabbit mochi: Sweet mochi dumplings decorated to look like rabbits, tying into the folklore story about a rabbit who lives on the moon and pounds rice into mochi.
• Tsukimi soba/udon: Noodle dishes topped with an egg to symbolise the moon.
• Tsukimi Burgers: Fast food restaurants often serve special Tsukimi burgers that include a fried egg, which represents the moon.
• Kenchin-jiru: A vegetable soup that uses autumnal ingredients such as daikon, carrots and burdock root, offering a hearty bite perfect for chillier evenings.
• Chestnuts (Kuri): A warming seasonal treat, also often serving as offerings to the moon.
• Sweet Potato (Yaki-imo): Baked sweet potatoes are an absolute autumnal staple. It may also be served with rice, with the yellow sweet potato chunks serving as another reminder of the full moon.
• Taro (Satoimo): Similar to a sweet potato, taros are often enjoyed in the form of kinukatsugi, a dish that involves steaming or boiling a taro with the skin on, then peeling back the skin and adding salt.
• Persimmon (Kaki): A sweet, crisp seasonal fruit enjoyed throughout autumn.
