When Is Obon? Japan's Obon Season, Explained

Obon (お盆) is one of Japan's most important traditional festivals, observed each year from August 13 to 16 in most of Japan and in mid-July in some regions.

During obon season, it is believed that the spirits of ancestors return to visit their families.

Japanese people welcome them with welcome fires (mukaebi), make food offerings at home altars and ancestors' graves, perform the bon odori folk dance, and send the spirits back with farewell fires (okuribi) on August 16.

Obon is not an official holiday in Japan but is widely observed as a family holiday, with most workers taking time off during what is commonly called obon week.

This article covers the origins, history, and customs of obon to help you understand and appreciate Japan's most beloved summer festival.

What is Japan's obon season? 

Honoring of one's ancestors remains a predominant tradition throughout Japan. During obon season, tradition has it that one's family's deceased members return to earth where they are welcomed into one's home and worshiped.

Customs include lighting welcome and farewell fires, making offerings, cleaning deceased family members' graves, and performing a bon odori to entertain the ancestors prior to their return to the spirit world. 

What are the origins of obon? 

The official name of obon is 盂蘭盆会 = urabone or 盂蘭盆= urabon. One theory has it that the word "urabon" is derived from the Sanskrit word Ullambana, which means "the pain of hanging upside down." 

According to the Ullambana Sutra, the central figure of the origin story is a Buddhist monk named Maudgalyayana (known in Japanese as Mokuren and sometimes referred to as Maha Maudgalyayana), one of the most gifted disciples of the Buddha.

Through his supernatural powers, Maudgalyayana saw his deceased mother suffering in the realm of hungry ghosts, a lower realm in Buddhist cosmology reserved for those consumed by greed during their lifetime. The hungry ghosts are depicted as ravenously hungry and thirsty, but everything they attempt to consume turns to fire, so they can never be satisfied.

Hoping to save her, he asks the Buddha for advice and Buddha replies, "If you make offerings from your heart to many high priests on the 15th day of the seventh month of the lunar calendar [around the middle of August in the present day], you will be able to save your mother from suffering.”

Maudgalyayana does as instructed, makes offerings of food and clothing to the Buddhist monks attending their annual summer retreat, and his mother is freed from the realm of hungry ghosts.

Overjoyed, he claps his hands and dances in celebration. This joyful dance is widely believed to be the origin of the bon odori, the folk dance performed during obon. The bon dance thus began not as a ritual of mourning but as an expression of joy and gratitude.

It is said that after this sutra was introduced to Japan, the obon festival began, including visits to graves and the lighting of welcome fires to express gratitude to the ancestors.

The Japanese kanji 盆 = bon also describes a container for placing offerings. Through the passage of time, it has also become a name for the spirits who are enshrined. In some places, spirits are called bon-sama.

When is obon celebrated? 

Currently, there are two primary dates when obon is observed: July 15 and August 15. The reason for this is that when Japan's calendar was modernized during the Meiji era, some areas held the event on July 15 of the new calendar, while others held it in August to keep with tradition. 

In Tokyo, many wards hold the ceremony in July, but the most common period nationwide is said to be the four days from August 13 to August 16.

The calendar of events for obon celebrations generally looks like this: 

• August 13: Welcoming one's ancestors

• August 14 - 15: Visiting graves and making offerings

• August 16: A farewell fire for one's ancestors

The bon odori festival may take place on any day throughout August 13 and 16.

How many days is obon in Japan?

Obon in Japan spans four days in most regions: August 13 as the welcoming day, August 14 and 15 for visiting graves and making offerings, and August 16 as the farewell day when the okuribi fire guides ancestral spirits back.

In regions that observe the July dates, the same four-day structure applies starting July 13.

The most spectacular farewell ceremony in Japan takes place in Kyoto on August 16 at 8pm.

Called Gozan no Okuribi (五山送り火), it involves five enormous bonfires lit on the mountains surrounding Kyoto, each in the shape of a kanji character, a boat, or a torii gate.

The fires are lit in sequence at five-minute intervals and are believed to guide ancestral spirits back to the spirit world. The event, which dates to at least the 13th century, is also known as the Daimonji festival after its most famous fire, the kanji character 大 (meaning "large") lit on Daimonji-yama. It is one of the most visually dramatic events in Japan's annual calendar and draws hundreds of thousands of viewers to Kyoto every August 16.

Is obon a national holiday? 

Although obon is not an official holiday in Japan, around 60% of businesses close during this period.

Many Japanese employees receive a longer break of 7 to 15 days during what is commonly known as obon week, making it one of Japan's three major holiday travel seasons alongside New Year and Golden Week.

Public transport and accommodation prices typically rise significantly during this period as people travel to their family homes.

What happens during Obon?

Many things happen during obon in Japan. Two main things happen: visiting family and going to local festival celebrations. Let’s take a further look at them.

What is mukaebi and okuribi? 

The welcome fire, 迎え火 = mukaebi, is lit on the evening or the night of August 13 to mark the return of one's ancestors to this world, helping to guide them so they do not get lost. 

The farewell fire, 送り火 = okuribi, follows the same pattern as mukaebi, except it is burned on August 16, as a farewell to the ancestors who have spent time with us during obon.

Today, ogara (hemp stalks) are burned or lanterns are lit in place of actual fires, often at the threshold of one's house or leading to one's ancestors' graves.

What type of offerings do individuals make during obon? 

Obon offerings お盆のお供え物 = obon no osonaemono are unique to each region. In many areas, eggplant and cucumbers are displayed, but this is not a nationwide practice. Baskets of fruits or the ancestors' favorite snacks are also often chosen. 

Offerings will differ from household to household, but the purpose of all of them is to honor the spirits of one's ancestors.

What is bon odori or an obon festival? 

Bon odori (盆踊り), which means "bon dance," is performed throughout the obon period from August 13 to 16 and at many community festivals across Japan during July and August.

Rather than being fixed to a single date, bon odori events are held whenever local obon festivals take place in each community.

It is often seen as a way to entertain the ancestral spirits before they return to the other world and to celebrate the reunion of the living and the dead.

One of Japan's most famous bon odori festivals is Gujo Odori in Gujo, Gifu Prefecture, which runs for an extraordinary 32 nights from mid-July to early September, with all-night dancing on four special nights during obon week. Each region has its own distinct bon dance tradition with its own music, costumes, and steps.

While it is widely believed the origins of the bon dance have Buddhist roots, the folk dance soon transitioned to a local folk entertainment, where citizenry reveled in costumes, choreography, and music, and by the beginning of the Muromachi period (1333–1573), people began to beat drums and dance, and the festival transitioned to what is quite similar to its modern form.

Additionally, some traditions point to bon dances as a ritual to pray for a good harvest, as well as express gratitude to Mother Nature.

What happens during a bon odori festival? 

There are many variations to the bon dance, depending on your region. Music and dance steps will also depend on your region and city. In some areas, the dancers are predetermined, but for the most part it is generally understood that anyone and everyone can join in. 

Many festival goers don yukata (although it is not required) and dance around a yagura (raised stage), which functions as a stand for Japanese taiko drums and singers, who perform mostly traditional songs. Recently, anime and pop music also make their way into the evening's playlist. 

Outside of music and dancing, festival spots often include a line of stalls that sell Japanese street food and other treats, toys, and games for children to play.

What is toro nagashi?

Toro nagashi (灯籠流し) is the obon custom of floating paper lanterns on rivers, lakes, and the sea to guide ancestral spirits back to the spirit world at the end of obon.

Small paper or bamboo lanterns are lit with candles and released onto the water, creating a serene procession of lights flowing downstream.

The custom is often performed on August 16, coinciding with the farewell fires (okuribi), and is held at many locations across Japan including Hiroshima, where it also carries the significance of remembering those who died in 1945.

Tips for visiting Japan during obon

Obon is one of the most rewarding times to experience Japanese culture in person.

Bon odori festivals are open to everyone, including visitors and tourists. You do not need to be Buddhist or Japanese to join the dancing. Wearing a yukata is common and welcomed, and many festival sites have stalls where you can rent one nearby.

Plan transport and accommodation well in advance.

The obon travel peak in 2026 runs from August 8 to 16, and shinkansen tickets, domestic flights, and hotel rooms in major cities and rural hometowns sell out weeks ahead.

Travelling between cities on August 13 and returning on August 16 will involve the heaviest rail and road traffic of the season.

Some shops, restaurants, and businesses in smaller cities and rural areas close for obon week. Major cities including Tokyo, Osaka, and Kyoto generally remain open. Museum and attraction ticket purchases in advance are recommended for popular sites during this period.

Is China's Hungry Ghost Festival related to obon in Japan?

China's Hungry Ghost Festival and Japan's Obon Festival share similar roots and themes, but the two traditional festivals are celebrated differently.

Both festivals are based on Buddhist and Taoist traditions and involve paying respects to ancestors and the deceased. They both occur around the same time of year and involve rituals intended to appease the spirits of the deceased, who are believed to visit the world of the living during this time.

In China's Hungry Ghost Festival, tradition goes that hell's gates are opened and ghosts are free to walk the earth, seeking food and entertainment. These ghosts are said to be ancestors of those who did not pay tribute to them after they died. People appease these hungry ghosts by offering food and burning 'hell money' and other forms of joss paper.

On the other hand, during Japan's Obon Festival, it's believed that the spirits of ancestors return to visit their relatives. Japanese people clean their houses and light lanterns to guide the spirits home, make food offerings, and visit their ancestors' graves. At the end of obon, floating lanterns are put into rivers, lakes and seas to guide the spirits back to the world of the dead.

So, while they share common themes of ancestor veneration and the belief in the mobility of spirits during a certain time of year, the specific customs and beliefs associated with the Hungry Ghost Festival and Obon are distinct to their respective cultures.

Bonus: Japan's summer greeting cards have obon origins

Japan's summer greeting cards 暑中見舞い = shochumimai are said to originate in obon customs. 

This summer manners guide published by Japan Post describes how during the Edo period (1603–1868) people would bring gifts to the spirits of their ancestors when they returned home for obon. 

For those homes that were too far away to visit, gifts and letters were sent in their stead. And with the development of the postal system in 1873, this custom of giving and receiving gifts was simplified into the custom of sending greeting cards. In the Taisho era (1912–1926), the current form of summer greeting cards was established. 

Frequently asked questions

When is Obon?

Obon 2026 falls from Thursday August 13 to Sunday August 16 in most of Japan. The four days follow a consistent calendar: August 13 for welcoming the ancestral spirits, August 14 and 15 for visiting graves and making offerings, and August 16 for the farewell fire that guides the spirits back. Some regions including Tokyo and parts of eastern Japan observe obon in mid-July (Shichigatsu Bon) instead of August (Hachigatsu Bon). Okinawa and some other areas follow the lunar calendar, resulting in slightly different dates each year.

What is Obon season?

Obon season is one of Japan's three major holiday periods alongside New Year and Golden Week. It runs from mid-July through mid-August depending on the region. For hachigatsu bon, the most widely observed version, the main days are August 13 to 16. In 2026, the peak of the obon travel season is anticipated to fall between August 8 and August 16, with the busiest departure days being August 8 and 11 to 13 and the busiest return days being August 15 and 16. Train tickets, flights, and accommodation in major cities sell out quickly and prices rise significantly during this window. Booking well in advance is strongly recommended for anyone visiting Japan or travelling within Japan during obon week.

How is Obon celebrated?

Obon is a traditional festival celebrated with various customs. Families who celebrate Obon usually gather in their hometowns, visit gravestones, perform rituals, and attend festivals. However, not every family follows the same customs.

Does Obon vary by region in Japan?

The celebration of Obon can vary by region. For instance, in Tokyo, Obon is celebrated around the 15th of July, while in other parts of the country, it's celebrated around the 15th of August. Some regions, like Okinawa, may have slightly different dates.

What is the significance of Obon?

Obon is one of Japan's most important festivals. It is a time to honor and remember the spirits of ancestors and loved ones who have passed away. The festival is marked by various traditions and customs, including visiting family graves and participating in the bon odori dance.

Is Obon like Day of the Dead?

Obon and Mexico's Day of the Dead (Día de los Muertos) share the central idea of welcoming the spirits of deceased loved ones back to the world of the living for a limited time each year, but they differ significantly in origin, practice, and atmosphere.

Obon is rooted in Buddhist tradition and derives from the story of the monk Maudgalyayana freeing his mother from the realm of hungry ghosts. It is observed through quiet family rituals including grave cleaning, food offerings at home altars, and the lighting of welcome and farewell fires. The bon odori dance is a communal celebration performed in large circles at outdoor festivals. The overall tone of obon combines solemnity with summer festivity.

Day of the Dead is rooted in a blend of indigenous Mesoamerican traditions and Catholic influence. It is observed on November 1 and 2 and centers on elaborately decorated altars called ofrendas, marigold flower offerings, face painting, and processions. It is considerably more colorful and visually exuberant in its public expression.

Both festivals treat the return of the dead not as frightening but as welcome and comforting, which distinguishes them from Halloween and similar Western observances. Obon is also commonly compared to China's Hungry Ghost Festival, which shares Buddhist roots but differs in its Taoist influences, its emphasis on appeasing unknown wandering ghosts rather than family ancestors, and the practice of burning joss paper offerings.

In closing

As we approach the Obon season, understanding its origins, significance, and associated customs can enhance our appreciation of this profound tradition. Whether you're participating in the festivities or simply observing, Obon offers a unique insight into Japanese culture and the enduring respect they hold for one's ancestors.
