Spring is a photographers dream in Japan, not only do you get the cherry blossoms which are spectacular but you get Wisteria blossoming everywhere too.
There are quite a few places you can travel to to see the Wisteria I chose to go to Ashikaga Flower park and Kameido Tenjin Shrine. Ashikaga was by far the most crowded, I have never seen so many people in a flower park before but the Wisteria there is impressive especially the 150+ year old trees, they are so well looked after.
Kameido Tenjin Shrine also has very impressive Wisteria but not the colour variety that you will find in Ashikaga. It is however much easier to get to and it is in a nice location with the sky tree behind it and it has 2 red bridges within the garden which are very photogenic.
If you just want to see Wisteria I would recommend the Ashikaga flower park because of the amount and variety that it has, but if you don’t have a lot of time and are not able to travel that far you cannot go wrong with Kameido. I cannot choose between the two and definitely think its worth seeing both if you can.
