Hi, GOwin-san!
Thanks for your question, we are making new details documents about this data in YAMATO city.
So, this is fire hydrants, but we are adding tourism function to real object with local government(= YAMATO city). We are thinking about landmark for tourism in the city, fire hydrants and AEDs have distinctive billboard. We are making new type of real fire hydrant with tourism function. OSM can define fact things, it means we can add emergency=fire_hydrant and tourism=information.
In addition, we will modify this name tag for unique names, thanks!! :-)

Thanks for great support from mappers. I guess, this newbie mapper is RISSHO University's student. Already, I've reported this edit to Teacher of RISSHO university.
We will make OSM class educational relationship in Japan.

Hi,
Please explain this house name.
I think, this is not house number.
We should delete this house name, is that right?

Thanks for you activities.
