Fireflies is flying

Here in Japan it’s very cold today. In the evening I tried to discover fireflies. And I found 20.
June 30 we have a firefly party at my log house DORONOKISYA. We will try barbeque or pizza or ONIGIRI. Do you know O-NI-GI-RI? It’s a rice ball.
If you come to the party, you can cook together pizza or ONIGIRI.
