Katori Senkou is what we need during the summer

Summer has come.
I like this season the most.
Traveling to seaside towns is a big fun for summer.
However, there is a thing that irritates us in this season.

It is mosquito.
They suck our blood.
In addition, sometimes mosquitoes carry viruses to us.
Even if they don't have any viruses, they are really irritating.
At around pond, thicket or grove, there are swarms of mosquitoes.
Everywhere we go to in summer, there they are!

Also mosquitoes invade into our house daily.
So, we have to do something to prevent their attack.

For preventing mosquitoes, there is Katori Senkou (mosquito coil).
Katori Senkou is a spiral shaped incense and used as a mosquito repellent.
It was invented by Ueyama Eiichiro in Japan in 1895.
It contains Jochugiku (pyrethrum) so it can kill mosquitoes.

In summer, the smoke from Katori Senkou are in the air in many houses.
While we smoke the incense, we can be safe from that irritating mosquitoes.
I have a nostalgia when I smell the perfume of Katori Senkou in every summer.
That reminds me of the summer in my childhood.
