I know that Jingu-Gaien is the area that is most famous for the yellow Ginko trees in the peak Autumn season.
However, it can also get extremely crowded.
It is ten minutes walk from Tokyo Tower, itself. If you’re having a hard time locating it, try putting the Minato Library into google maps as it is right next to the playground equipment.
So if you have small kids or just really dislike crowds, I recommend this yellow spot as a quieter alternative.
If you get your timing right, it’s spectacular. It looked like this on December 7th, 2017 and on December 2nd in 2018.
It is the perfect spot for hide’n’seek (and lots of playground equipment too.)
This is a playground section of Shiba Park called Shiba Koen Kodomo Heiwa Koen and it’s right next to Onarimon Station (Exit 10.)
You also have a great view of Tokyo Tower here.
There are public toilets here.
Even the pedestrian bridge on the way from Tokyo Tower gives a spectacular view of the Ginko trees.
The park, normally, isn’t majorly special, but in this season? Wow.
