Postcard JP-395000

kon ni chi wa Urara,
I am Leo, a newcomer to Postcrossing. you can read about me at Leo9Ely
While looking through the Gallery of cards registered by members, I found I am very fond of the cards sent from Japan. I want to use some of these to illustrate my personal preferences. I like JP-39500 for its design,the colours, the drama of the waves and the inclusion of the iconic Mount Fuji and Japanese calligraphy.Can you please let me know what the writing says.
best wishes Leo
