I got on a trip to the Ibaraki prefecture to reunite with friend after 6 years-ish. We spent a day at one of the most famous spot in town - Hitachi Seaside Park.
I have never seen so many colors in one day :)
You can find these types of flowers in any local flower shop. But the impact when seeing the whole landscape of them, is on another lever.
Some of those are already dying, though.
