Arai machi, since included into Hamamtsu City is bit of a strange place completely separated not only by the station (you have to pay 180 yen anytime you want to go to the other side) but also by a sea arm.
The interesting manhole covers lie south of the Arai Machi JR Station while the north housing the professional outboard boat races is pretty drab.

SOUTH SIDE:

The original manhole cover for Arai Machi!
I wonder what the colored one looked like!

Arai Ｍachi is really confusing as this manhole cover seems to belong to belong to neighboring Kosai City!

Same for this one, too!

This pressurized air manhole cover on the other hand solely belongs to Arai Machi!

Same for this water valve pit!

A smaller and different valve pit!

Now, this valve pit definitely belongs to Kosai City!

A smaller Arai Machi water valve pit!

A medium-sized gas valve pit in the middle of the road!

An even bigger gas valve pit still in the middle of the road! They were neighbors and I did take a risk photographing them! LOL

NORTH SIDE

It is the first time I such a shape for any manhole cover! A strange air access for firemen!

A very long one for “high electricity”!

Probably stands for high voltage electricity!

Same shape for “low electricity”!

I wonder if they mean “low electricity output” instead of low voltage electricity!

A sewer manhole cover by Ohtake foundry!

Same but with low voltage electricity indication!

A vertical marking instead of a round indication for low voltage electricity!

Same but for high voltage electricity!

Drainage manhole cover!

Shizuoka Prefecture electricity manhole cover!
