From around mid-April to early May each year, Gunma's Tsutsujigaoka Park in Tatebayashi is filled with color thanks to the 10,000 azalea bushes on the grounds. Breaking it down even further, the azaleas here are from 50 different varieties, including the likes of the purple maiden azalea, the white Ryukyu azalea, and the Asuka River azalea to name just a few.
The price of admission to the park differs slightly during the azalea season. When the flowers are at their peak, adult admission is 630 yen. When the flowers are just beginning to bloom or past their best, admission is only 310 yen.
As is the case with any flower festival, the dates can differ slightly from year to year depending on blooming conditions. As an estimate, last year's event ran from April 10th until May 15th, but do check the official website for a confirmation closer to April.
