Hamazaki Park is a small park located behind the Tokyo Gas headquarters, near the "Site of Gas Establishment" monument.
To get to Hamazaki Park, go from the south exit of Hamamatsucho Station and proceed along the pedestrian deck.

The pedestrian deck connects from the "Hinode Pier" area, which is located at the bottom left of the Hamamatsucho Station layout.
And, Hamazaki Park is located after you go straight on the pedestrian deck and down the stairs leading to Tokyo Gas.
It's a small park with lush greenery, located in a spot that's not very noticeable.
In fact, you probably wouldn't notice this park unless you go down the stairs from the pedestrian deck.
There were 3 benches, each with three seats.
The benches are in good condition, but for some reason, I didn't feel like taking a break...
When I visited, the outside temperature was around 32 degrees Celsius, and it was also the mosquito season.
There was a slide that seemed like you'd finish sliding in an instant.
The facilities are clean for such a small park.
I visited on a Saturday, but there were no people, let alone children...
However, as it's also a route to Hinode Pier for the water bus, the area near the stairs of the pedestrian deck might get crowded depending on the time of day.
On the Tokyo Gas side, there were 4 benches with three seats each and 4 stone benches with two seats each.
The benches in the front look like you could do sit-ups on them.
I don't really want to sit on the benches in the back...
It might be hard to tell from the photo, but it's in a desolate space sandwiched between the Shuto Expressway and the pedestrian deck, and I think it's an area that not many people other than Tokyo Gas employees visit.
By the way, there's a statue and a signboard near Hamazaki Park.
(It looks a bit like Resident Evil, haha)
Oh, it might be a bit scary if you see it at night.
It seems to be a "Moyai Statue."
This Moyai statue is made using porous stone (kōkaseki) produced on Niijima Island in the Izu Islands, and it was carved by the islanders.
What is porous stone!?
⇒ It's a type of pumice stone with a sponge-like structure, and it's characterized by being easily cut with saws and axes.
By the way, haven't you heard of the Moyai statue before?
That's right, the Moyai statue in Shibuya! The statue in Shibuya also uses the same porous stone from Niijima Island!
And, isn't it the Moai statue instead of the Moyai statue?
⇒ The origin of "Moyai" comes from the word "Moyau" used on Niijima Island.
In kanji, it's written as "催合う・最合う," which means "helping each other."
In other words, it has a different meaning from the Moai statues of Easter Island, which are guardian deities!
I see.
It was a rest area with this kind of trivia, but the atmosphere is so-so, so it gets one star...
Also, there are other Moyai statues located around Hamamatsucho.
Strolling around looking for Moyai statues is quite a niche activity, and it might be pretty interesting, haha.
By the way, the other spot is here (spoiler alert)
So, why not consider using it as a resting place where you can sit down around Hamamatsucho?
