Each year during spring, Ibaraki's Kokaigawa Fureai Park comes alive with the color of around two million poppies in bloom. There are so many flowers that the ground almost looks blanketed by them, and the addition of Mount Tsukuba as a backdrop makes this park a photographer's delight. The poppy flowering period is typically throughout the month of May, and updates about their status will be posted on the park website (in Japanese).
The venue is divided into "zones", and along with the flower zone, visitors can also enjoy a children's zone filled with play equipment, a sports zone comprising of 4 softball fields and a soccer field, and even a barbecue zone where you can grill some lunch and make a day out of your visit (reservations are required).
