During the cold Japanese winter, an onsen can warm you up. Many of the hotels and lodges in Hagi have onsens. There are also onsen facilities that you can visit on day trips.

The Hina Doll Festival in Hagi Castle Town is an event that takes place in February and March.

The Hina festival is an annual Japanese event held in the hopes of healthy growth and happiness for girls. During this event, 1,200 precious Hina dolls handed down by households in Hagi are displayed at multiple venues around the city. From the Edo period to modern times, the faces and costumes of Hina dolls have changed over the ages, and a variety of distinctive dolls can be viewed during this event.

There are also beautiful flowers to be enjoyed during the winter in Hagi.
The camellia is Hagi’s most emblematic flower. At the foot of Mt. Kasa is the Mt. Kasa camellia forest — a large area where approximately 25,000 camellia trees grow wild. The blossoms are best viewed from mid-February to late March. These camellia trees are quite tall, five to six meters in height, and their white trunks stretch off into the distance, which makes for a fantastic sight. When the flowers are in full bloom, the fallen camellias that color the ground red are also beautiful. The Hagi Camellia Festival is held each year during the period when the bright red camellia blossoms are best viewed, and it attracts numerous visitors each year.

Ume trees bloom a bit earlier than camellias. The Hagi Okan Ume Orchard contains about 250 ume trees. Visitors can enjoy the fragrant scent and colorful blossoms of the ume trees.

In Hagi, the Kawazu cherry trees bloom from late February to mid-March in a typical year, which is a bit earlier than the Yoshina cherry blossoms that are emblematic of spring. There are about 120 of these trees, which have distinctively intense pink blossoms, arrayed around Shinsui Park, and it is a breathtaking sight to see them all in blossom at once!
