What Is Katori Senkō (蚊取り線香)? Japan's Iconic Mosquito Coil
On warm summer evenings in Japan, you might notice a thin trail of smoke rising from a small green spiral.
It isn't incense.
It's Katori Senkō (蚊取り線香)—Japan's famous mosquito coil.
For more than a century, these slowly burning spirals have helped keep mosquitoes away while becoming a nostalgic symbol of Japanese summer.
Let's discover why they're still loved today.
What Is Katori Senkō?
Katori Senkō (蚊取り線香) is a spiral-shaped mosquito coil designed to repel mosquitoes with its smoke.
The name means:
- 蚊 (ka) – mosquito
- 取り (tori) – to catch or remove
- 線香 (senkō) – incense stick
Unlike incense made for fragrance, mosquito coils are made to burn slowly for several hours while releasing mosquito-repelling ingredients.
Why Is It Spiral-Shaped?
The spiral isn't just for decoration.
A long strip is rolled into a spiral so it can burn very slowly without taking up much space.
One coil typically burns for 6 to 8 hours, making it perfect for relaxing outdoors on summer evenings.
How Is It Used?
A small metal stand is placed through the center of the coil.
Once lit, only the tip burns.
The glowing ember slowly travels around the spiral while producing a gentle stream of smoke.
Many people place mosquito coils:
- On patios
- In gardens
- At campsites
- Near open windows
- During fireworks festivals
- While fishing or gardening
The Famous Pig Holder
One of Japan's most recognizable summer items is the pig-shaped mosquito coil holder.
Known as a Kayari Buta (蚊遣り豚), this ceramic pig safely holds the burning coil inside while allowing the smoke to drift out through its nose and side openings.
Today, the cheerful pig has become almost as famous as the mosquito coil itself.
Do People Still Use Them?
Yes.
Although electric mosquito repellents and sprays are now common, many households still enjoy mosquito coils for outdoor activities.
Some people simply love the nostalgic scent that reminds them of summer.
How do you pronounce Katori Senkō?
It is pronounced:
kah-toh-ree sen-koh
Japanese: 蚊取り線香
