As you guys may or may not know, the Japanese cherry blossom festival, Hanami, passed a couple of weeks ago. It's held all over Japan in spring and people view the lovely cherry blossom trees that are in bloom in that period. I live very close to a Japanese Garden (for the ones in Belgium: it's in Hasselt) that also celebrates the event and it's amazing to see the whole garden full of pink flowers.
Unfortunately this year I didn't go, since it has been raining for weeks on end. Hopefully next year the weather will be better, but I do have some pictures left from last years Hanami festival when the sun was shining and it was unusually hot for april!
If you want to see the Japanese gardens, they celebrate important Japanese holiday events so it's nice to go on a day like this to see something new! You could go on Children's day in May, or my personal favorite: the star festival Tanabata in July.
You can buy a crane bird for good luck, and it gets added to a string of them in the garden.
Don't forget to bring some food for the massive koi fish!
