How are you doing ? I think Japan is a dream destination for a lot of people including me.
Last fall, I visited Japan for the first time and it impressed deeply in my heart.
I'm curious that whether you all know this place or not ? "Kamikochi" It's quite popular in my country.
They open this place for camping and trekking in Summer and close in November (Depends on each year)
I saw the picture of this mountain in Summer once and it was very beautiful.
