Learn about the climate and clothing of Kirishima City, Kagoshima Prefecture, where myths and legends live on

Kirishima City in Kagoshima Prefecture is known as the land where the myth of the descent of the heavenly grandson, which appears in the "Kojiki" and "Nihon Shoki," has been passed down, and it is also famous as the destination of Sakamoto Ryoma's honeymoon. The Kirishima mountain range, a group of volcanoes, spreads out in the northern part of the city, and Kinko Bay lies to the south, with Sakurajima puffing smoke. All of these are within the Kirishima-Kinko Bay National Park, and the area is dotted with spots where history lives on, such as Mount Takachiho, said to be the place where the gods descended from the heavens to the earth, and the "Kirishima Jingu Shrine," which is said to have been founded in the 6th century.

It is also famous as a representative hot spring area in Kagoshima Prefecture, and the four major hot spring resorts, including "Hinata-yama Onsen," which Saigo Takamori often visited, are popular. The climate is mild throughout the year, but it is known for having one of the highest levels of rainfall in the country, so it is important to take measures against rain for your feet if you visit during the rainy season or the long autumn rains. The humidity in summer is also among the highest in the country, and the city area remains sultry, but the Kirishima Highlands, at an altitude of 500m, have a comfortable climate with an average temperature of 25°C. The temperature difference between morning and evening is large around the Kirishima mountain range, so be sure to prepare an extra layer of warm clothing for each season.

In early March, the weather fluctuates between cold and warm, with some days seeing lows of 2°C and highs of 20°C. By late March, when the average high temperature exceeds 15°C, the cherry blossoms begin to bloom. In early April, the cherry blossoms at ancient temples like Kirishima Jingu and in local parks reach full bloom. A knit sweater or cardigan is sufficient for daytime cherry blossom viewing, but be sure to bring a coat as temperatures drop significantly at night.
From mid-April onwards, when the mountain climbing season opens, the Kirishima mountain range is colored with flowers. The 'Nokaido' (Malus spontanea), a member of the rose family that grows wild only on the Ebino Plateau, is in bloom from mid-April to mid-May. In late April, the 'Hikage-tsutsuji' (Rhododendron keiskei) blooms yellow on Mt. Ebino, and from mid-May onwards, mountains over 1,500m such as Mt. Takachiho-no-mine are dyed in the deep pink of 'Miyama-kirishima' (Rhododendron kiusianum). You can also spot delicate flowers like the 'Haru-rindo' (Gentiana thunbergii) at your feet. The temperature during this season, when many hikers visit for flower viewing, is about 19°C. Keep in mind that temperatures drop by 0.6°C for every 100m of elevation when choosing your clothing.

The rainy season typically begins between late May and early June. Rainfall is heavy, and it is not uncommon for rain to continue for about a week. The average temperature during the rainy season is about 23°C. Even so, it can feel chilly, so you will want a light jacket. If you are going for a walk or hike in the highlands, choose clothing with cold and wind protection.
The average temperature in July and August is about 26°C. While this is 1–2°C lower than summer in Tokyo, the humidity is about 5% higher. After the rainy season ends in late July, the humid heat characteristic of Kagoshima begins, so breathable clothing is best. A great place to visit during the hot summer is the 'Forest Therapy Road' created around the Kirishima Shinsuikyo Gorge and the Kirishima Highlands, located at an altitude of 500m to 700m. You can enjoy forest bathing while feeling the refreshing breeze. The Kokubu Camp Beach on the northern shore of Kinko Bay, which offers a panoramic view of Sakurajima, is also very busy. We also recommend cooling down from the inside with the local specialty shaved ice dessert, 'Shirokuma'.

Autumn in Kirishima is packed with events. Starting with the "Kirishima City Fireworks Festival" held in late September, it continues with the Kagoshima Jingu Shrine warrior procession "Kirishima Hayato Hama-kudari" in mid-October, the "Tenson Korin Goshinka-sai" (Heavenly Grandchild Descent Sacred Fire Festival) at Kirishima Jingu Shrine on November 10th, and the Niiname-sai (Harvest Festival) on November 23rd. There are many Shinto rituals at historic shrines, so visiting them while touring power spots is also recommended.
While the heat still lingers in early September, the average temperature from mid-September to October is around 20°C, making it comfortable to wear shirts or cardigans. There are many sunny days, making it perfect for outings. The autumn foliage begins in late October. There are many famous spots such as "O-nami-ike," a crater lake on Mount Kirishima where the surrounding mountains are dyed in brocade, and the "Ebino Plateau," which features vast fields of Japanese pampas grass. In November, when the autumn leaves are at their best, the average minimum temperature drops to about 8°C, so be sure to wear warm clothing like coats and stoles when going out for autumn leaf viewing.

Although Kagoshima Prefecture has an image of being warm even in winter, Kirishima City, where the Kirishima mountain range towers, often has days where the minimum temperature drops below freezing. In December, when the average minimum temperature is about 3°C, the Kirishima mountain range is usually completely covered in snow, and rime ice can also be seen. While you can ward off the cold with a thick coat when walking around town, be sure to take cold-weather precautions such as snow boots and down coats in high-altitude areas. January and February, when the New Year is welcomed with the "Tenson Korin Kirishima Kumen Daiko" (Heavenly Grandchild Descent Kirishima Nine-Mask Drum) performed at Kirishima Jingu Shrine, are the peak of the cold. The average temperature drops to around 6°C.
Famous as a hot spring area, Kirishima attracts many people to its renowned hot springs, such as the four major hot spring resorts at the foot of the Kirishima mountain range, where visitors enjoy touring springs with different water qualities and benefits. In late February, when the yellow "Mansaku" (witch hazel) flowers begin to bloom around the snow-melting O-nami-ike, signs of spring appear. Since this is a time when the temperature difference is large, with maximum temperatures still above 10°C and minimum temperatures below freezing, be sure to stay warm with appropriate clothing.
