It's a lovely park with many beautiful flowers and lovely elderly staff. We were abit offseason, bit late for sakuras and too early for wisteria (which was a pity). The tulips were in full bloom though! Note if you come from Hamamatsu train station, it's a direct bus 30 from the bus terminal outside the train station. However, it's a 45min ride and bus frequency is not that often. Advise to check before you go. Tip: note google maps will tell you to alight at the 'zoo' stop which is the other entrance. You can get off a few stops earlier at the western gate and save yourself a long walk. Look out for the Flowerpark on the opposite side of the road.
