There are things you won't see just by opening an event calendar when trying to learn about festivals on Amami Oshima.
The island has a large festival where fireworks are set off and many people gather.
On the other hand, there are harvest festivals held in small villages, waiting for the day according to the lunar calendar.
The day to put pampas grass under the eaves of the house.
The day we go down to the sea.
A day off from mountain work.
The day to welcome our ancestors.
The day to offer new rice.
A night spent dancing from house to house in the village.
In Amami, these small observances have also shaped the year in each shima community.
This article introduces festivals and annual events that can be confirmed from publicly available documents, focusing on the five municipalities of Amami Oshima Island that Amami Experience primarily covers—Amami City, Tatsugo Town, Yamato Village, Uken Village, and Setouchi Town—as well as Kakeroma Island, Uke Island, and Yoro Island, which belong to Setouchi Town.
This involves cross-referencing the results of on-site surveys of festivals and events conducted by the Kagoshima Prefectural Board of Education with the materials currently made public by each local government.
However, there are some things that cannot be ascertained solely from publicly available online documents, such as family rituals, private events, and events that are currently suspended.
Please read this article as a "Comprehensive Overview of Amami Oshima's Festivals Based on Publicly Available Information."
How to read dates | Reading the old and new calendars together
Many traditional events in Amami are based on the lunar calendar or the Chinese zodiac, rather than the modern Gregorian calendar.
for example,
The third day of the third month in the old lunar calendar.
The 15th day of the 8th month in the old lunar calendar.
The first hinoe (丙) day of the eighth lunar month.
Seven days later, the mizunoe (壬) day.
That's how the decision is made.
Therefore, this article will include both the traditional lunar calendar and the Gregorian calendar as reference points to help travelers visualize the timing.
for example,
The 3rd day of the 3rd month in the old lunar calendar → Usually around April in the new calendar.
The 13th to 15th of the 7th month in the old lunar calendar → Usually around August to September in the Gregorian calendar.
The 15th day of the 8th month in the old lunar calendar corresponds to around September or October in the Gregorian calendar.
That's how you read it.
However, the corresponding dates between the lunar calendar and the Gregorian calendar change every year.
Furthermore, because it is now difficult to hold the festivals on weekdays, some communities have moved the actual dates to Saturdays or Sundays that are closer to the traditional dates. Yamato Village also explains that it sometimes holds the Jugoya Hōnen Matsuri and Kugatsu Kunchi on the nearest Sunday, based on the festival dates in the old lunar calendar.
therefore,
The old calendar = the original reference date for events.
Gregorian calendar guidelines = guidelines for considering travel dates
Actual event date = the date decided by the local government/village in that year.
The basic approach is to consider them separately.
Another key to understanding Amami's customs: "Shima"
In Amami, settlements are called "shima."
Even on Amami Oshima, neighboring shima communities may dance to different songs.
The date of the harvest festival is different.
Even though they're all August dances, the hand movements and melodies are different.
An observance may survive in one shima community while having disappeared in another.
The festivals in Amami do not share a single format across the entire island.
These traditions have been passed down with the differences between individual shima communities intact.
January (New Calendar) | Events to welcome the new year
At the beginning of the year, New Year's celebrations based on the Gregorian calendar and those based on the lunar calendar overlap.
New Year's celebrations are held on January 1st according to the new calendar.
On January 2nd of the new calendar, there are the Sekkunoyoe and Funayoe festivals.
On January 7th of the new calendar, events such as Nankansek are performed.
In Yamato Village, boats are purified with sake and salt during the boat celebration, and prayers are offered for safe voyages and a bountiful catch throughout the year. The "start of farming," in which those involved in agriculture symbolically begin working in the fields and mountains, is also a tradition.
on the other hand,
The 16th day of the first month of the lunar calendar corresponds to around February or March in the Gregorian calendar.
There is a mountain god festival there.
It has been considered a day when the mountain gods descend, and people have been asked to take a break from mountain work and refrain from entering the mountains.
Lunar March 3 | Usually around April in the Gregorian calendar | Sangatsu Sekku and the Going Down to the Shore Ritual
The third day of the third month in the old lunar calendar is called Sangatsu-sekku or Sangatsu-sanchi.
In the Gregorian calendar, this generally falls between late March and April, depending on the year.
The custom of going down to the beach, playing in the tide pools, and eating mugwort rice cakes has been passed down through generations.
In Yamato Village, it is said that this was once such a common event that people would finish school or work by noon and head to the beach with their families and friends.
In Uken Village, the Going Down to the Shore ritual is recorded as a traditional observance in Ashiken, Hirata, Yadon, and other communities.
The day of the Monkey in the fourth month of the lunar calendar | Usually around May-June in the Gregorian calendar | Hamaore Mushiasobi
Hamaore in the Kasari district of Amami City is a traditional observance based on the first Monkey day of the fourth lunar month.
In the new calendar, this usually falls around May or June.
This ritual involves gathering pests from fields and sending them to rivers or the sea, in order to pray for a bountiful harvest.
In the past, there were areas where people ate and drank on the beach, or went boating.
Amami City continues to introduce Hamaore as a community observance in the Kasari district.
The 5th day of the 5th month in the old lunar calendar | Usually around June or July in the Gregorian calendar | Gogatsusek
The 5th day of the 5th month of the lunar calendar is Tango no Sekku, also known as Gogatsu Sekku or Gogatsu Gonchi.
In the Gregorian calendar, this usually falls around June or July.
In Yamato Village, the custom of hanging irises and mugwort from the eaves of houses and eating akumaki (a type of sweet) is described as a way to ward off evil spirits.
In the 2026 Yamato Village official calendar, the 5th day of the 5th month of the lunar calendar corresponds to June 19th in the Gregorian calendar.
Lunar calendar June | Typically July-August in the Gregorian calendar | Rokugatsu-to (June Lantern Festival)
In the Kasari district, the Rokugatsu-to festival, which enshrines the local guardian deity, is held in the sixth month of the lunar calendar.
In the new calendar, it's usually around July or August.
The villagers clean the shrine, put up banners and lanterns, and pray for prosperity and a bountiful harvest.
In some villages, theatrical performances and August dances are held.
July 7th in the old lunar calendar | Usually around August or September in the Gregorian calendar | Tanabata
In Amami, Tanabata is deeply intertwined with the Obon festival.
The 7th day of the 7th month in the old lunar calendar usually falls around August or September in the Gregorian calendar.
In 2026, August 19th in the Gregorian calendar corresponds to July 7th in the lunar calendar. This correspondence can also be confirmed on the official calendar of Yamato Village.
In Yamato Village, a tradition explains that the reason for erecting tall Tanabata bamboo poles is to serve as a landmark so that ancestors returning during the Obon festival do not get lost.
The 13th to 15th of the 7th month in the old lunar calendar | Usually around August to September in the Gregorian calendar | Obon festival
In Amami, many areas still observe the Obon festival according to the lunar calendar.
The 13th to 15th of the 7th month in the old lunar calendar corresponds to around August or September in the new calendar.
In the case of 2026,
The 13th day of the 7th month in the old calendar is the 25th day of the 8th month in the new calendar. The 14th day of the 7th month in the old calendar is the 26th day of the 8th month in the new calendar. The 15th day of the 7th month in the old calendar is the 27th day of the 8th month in the new calendar.
This corresponds to [the relevant category].
In Yamato Village,

Offerings were made on the 14th.
On the 15th, we sent our ancestors to their graves.
The custom of young people performing the August Dance, known as Ashinare, on the night of the 15th is introduced.
August in the old lunar calendar | Typically September-October in the Gregorian calendar | A season when many festivals are held.

In the Gregorian calendar, this usually falls around September or October.
During this period,
Arasetsu
Shibasashi
Dunga
Jugoya
Harvest Festival
August Dance
These events will be held in various locations.
It's important to note that Arasetsu, Shibasashi, and Dunga are determined by the Chinese zodiac, so they don't always coincide with the full moon on the 15th day of the 8th month of the lunar calendar.
It becomes easier to understand if you think of it as a single month, the eighth month of the lunar calendar, where holidays determined by multiple criteria overlap.
First Hinoe Day of Lunar August | Usually around September–October | Arasetsu
Arasetsu is observed on the first hinoe (丙) day of the eighth lunar month.

In Uken Village, there are records of Shibasashi in areas such as Ikegatsu and Amuro.
First Kinoe-ne Day after Shibasashi | Usually around September–October | Dunga
Dunga is based on the first kinoe-ne (甲子) day after Shibasashi.
