Hands down, my favourite thing to do in this area with my children is to go to Arisugawa Park. It is stunning and completely different with every single season. It has a lovely children’s playground up the top of the hill and a Japanese garden with a large pond down the bottom. It’s perfect for turtle, duck and carp spotting! There is a public bathroom up the top near the playground equipment and another down near the pond. Wear mosquito repellant in Summer and Rainy Season.
The park is just 2 minutes walk from Hiroo Station.

See here if you’re looking for more family-friendly options in areas around the park such as Hiroo, Roppongi and Azabujuban.
In my Hiroo with kids post I have coffee and restaurant suggestions too.
