This is what is happening now. Since last Friday and until December 2nd, Ritsurin Garden will stay open until 9pm (it usually closes around nightfall). For the occasion the garden has special illuminations and also various events such as concerts on the week-ends.
So if you have the opportunity to go to Takamatsu before December 2, make sure you don’t miss seeing Ritsurin Garden at night.
As I didn’t go yet (that was the plan for today, but the weather decided otherwise), here are the pictures I took last year (not my best pictures, I still need to learn how to better take night pictures) but that will give you an idea.
Of course, no picture can do justice to the actual Ritsurin Garden’s beauty.
