Okinawa Autumn and Winter: Mild Climate and Vibrant Seas in the Hidden Best Season

Okinawa Autumn and Winter Trip

From October to February, Okinawa is an off-season when the typhoon season ends and the summer crowds settle down. Even so, the climate stays warm: the normal daily mean temperature in Naha is 25.5°C in October, 22.5°C in November, 19.0°C in December, 17.3°C in January and 17.5°C in February (Japan Meteorological Agency normals for 1991 to 2020). It is a calm travel season when you can enjoy island time at a leisurely pace. Airfare and accommodation costs also become reasonable, making it a recommended time especially for those who want to travel wisely.

October to November

The time when the typhoon season ends and the climate is most stable. There are also fewer tourists, and accommodation costs are reasonable. The sea is still warm, and the transparency for diving and snorkeling is also kept high, so marine activities can be fully enjoyed. During the day, the weather is warm enough to spend in short sleeves.

December to February

The normal daily mean temperature in Naha is 19.0°C in December, 17.3°C in January and 17.5°C in February (Japan Meteorological Agency), warmth like the spring of Honshu. While swimming in the sea is tough, it is comfortable for sightseeing, driving, gusuku (castle) tours, and cultural experiences. From winter into early spring, humpback whales visit the waters near Okinawa to breed and raise their young. Around the Kerama Islands, the Zamami Village Whale Watching Association usually runs tours from early January to late March (in 2026, January 8 to March 25). December is often still outside the operating period, so check the latest information from each operator for your dates.

Kanhizakura, the Cherry Blossom That Blooms Early

From late January to early February, "Kanhizakura" comes into bloom in various places a step ahead of Honshu. At the "Nakijin Gusuku Sakura Festival" held at the Nakijin Castle Ruins, you can enjoy the cherry blossoms together with the light-up of the World Heritage gusuku. The 19th edition ran from January 31 to February 8, 2026 (check the official Nakijin announcement for the next edition). Admission to the Nakijin Castle Ruins is 1,000 yen for adults, 500 yen for junior high and high school students, and free for elementary school age and younger (revised September 1, 2025).

Japan's Earliest Cherry Blossom Festival: Mount Yaedake in Motobu Town

When it comes to cherry blossoms in Okinawa, the other place you cannot leave out is Mount Yaedake in Motobu Town. According to the Motobu Town Tourism Association, Yaedake is the second-highest mountain on Okinawa's main island at an elevation of 453.4 meters, and rows of more than about 7,000 kanhizakura trees line both sides of the roughly four-kilometer climbing road to the summit. Around the time of the "Motobu Yaedake Cherry Blossom Festival," known as "Japan's earliest cherry blossom festival" and held in January, the whole mountain is dyed with flowers, and the contrast between the deep green primeval forest and the vivid scarlet of the kanhizakura leaps out at you.

"Yaedake Sakura no Mori Park" on the mountainside (921 Aza Namisato, Motobu Town) has play equipment, rest facilities, toilets and a multipurpose open space, with parking for about 500 cars. Inquiries go to the Motobu Town Planning, Commerce and Tourism Division (0980-47-2700), and on Saturdays and Sundays during the cherry blossom festival the park management building (0980-47-6688) serves as the contact point. The dates shift from year to year and may be extended depending on how the blossoms open, so be sure to check the latest announcements from Motobu Town and the tourism association.

Places to Stop By in Autumn and Winter

If you are visiting the Nakijin Castle Ruins or Mount Yaedake, it is efficient to go around the facilities gathered on the Motobu Peninsula together.

• Okinawa Churaumi Aquarium (Motobu Town, inside Ocean Expo Park): usual opening hours are 8:30 to 18:30 (last admission 17:30). Apart from temporary closures for typhoons and the like, there are in principle no closed days, including the New Year period. The huge "Kuroshio Sea" tank where whale sharks swim is its signature attraction. Note that Ocean Expo Park itself has different opening hours in the regular season (October to February) and the summer season (March to September).
• Nakijin Castle Ruins: located on the north side of the Motobu Peninsula, where undulating rows of stone walls look down on the sea. It is an easy drive from Yaedake and the Churaumi Aquarium.
• Kerama Islands: the base for whale watching. Ferries run from Naha's Tomari Port to Zamami Island and others.

The Look of Autumn and Winter, and What to Wear

According to the Japan Meteorological Agency normals (1991 to 2020), the daily mean temperature in Naha is 25.5°C in October, 22.5°C in November, 19.0°C in December, 17.3°C in January and 17.5°C in February. Looking at the numbers alone this is close to spring in Honshu, but how it feels is quite different.

• October to November: short sleeves are enough during the day. The sea is highly transparent and marine activities can be enjoyed comfortably.
• December to January: there are days with a strong north wind, and when the wind picks up the perceived temperature drops sharply. Long sleeves with a light outer layer, plus one windproof jacket, will put your mind at ease.
• February: the kanhizakura heads toward the end of its season and the sunlight gradually grows stronger. Even in winter you need protection from ultraviolet rays.

Because the gap between morning and evening and midday, and the presence or absence of wind, changes how it feels so much, clothing you can adjust in layers is the right answer.

Photography Tips

• Kanhizakura does not open facing upward like Somei-Yoshino; its deep pink flowers bloom facing downward. Shooting from directly below at an upward angle, with the blue sky or the sea in the background, brings out the shape and color of the flowers.
• At the Nakijin Castle Ruins, layering the line of the undulating stone walls with the cherry blossoms makes for a distinctly Okinawan shot. This is a World Heritage historic site, so climbing on the stone walls or entering no-entry zones is strictly forbidden.
• The nighttime light-up is a scene where you will want a tripod, but the cherry blossom festival period is extremely crowded. Always follow the guidance of the organizers and on-site staff about whether tripods may be used and where they may be set up.
• On whale watching trips the boat rocks heavily. Securing your equipment to your body with a strap and setting a faster shutter speed in advance will reduce failures.

Best Season

If you want to spend time leisurely, October to November is the target; for kanhizakura, late January to early February; and for whale watching, January to March. Since it can get cold in the mornings and evenings, having a light layer to throw on gives peace of mind.

Access

Flights to Naha Airport operate year-round. In the off-season, cheap airfares are easy to get, and reservations are also relatively smooth.

Practical Information

• Best season and time of day: for a leisurely stay, October to November. Whale watching in the Kerama Islands usually runs from early January to late March (in 2026, January 8 to March 25).

• Access: reaching the Nakijin Castle Ruins is basically done by car, such as a rental car, from Naha Airport. For the Kerama Islands, take a ferry from Naha's Tomari Port to Zamami Island and others.
• Parking: the Nakijin Castle Ruins have about 320 spaces in total across car parks No. 1 to No. 4, free of charge.
• Photography rules: the Nakijin Castle Ruins are a World Heritage historic site. Please do not climb on the stone walls or enter no-entry zones. During the cherry blossom festival there are nighttime displays and it is extremely crowded, so always follow the guidance of the organizers and on-site staff about whether tripods may be used and where they may be set up.
• Safety notes: ultraviolet rays are strong even in winter, while mornings and evenings are chilly, so bring a light layer to throw on. On whale watching trips the boat rocks heavily. Do not forget to prepare motion-sickness medicine, and trips are cancelled on days when the sea is rough. The stone paving and stone steps at the castle ruins are slippery in the rain, so wear shoes that are easy to walk in.

*The operating period for whale watching changes from year to year. December is often still outside the operating period, so be sure to check the latest information from each operator.*
