I
cannot
find the Japanese translation for it other than "manhooru". I found
it in the older road side of Ozasaki. Unlike the official manhole
cover plates containing the city name, department name with a year or number
reference, it depicts a Japanese Castle (Joo) at night, with firework blazing
in the sky and flower bed -- probably Sakura, decorating the foreground.
On the lower left, it imprinted discreetly: "osui", I supposed it means
water line.
Then,
there was this abstract cover plate with no indication of whatever it was
for. Or perhaps the main task for the repairmen is to know how to
read the hidden meaning. And then came Indiana Jones who would have
put all of them out of work.
In
Nagoya, I found this plate depicting the industrial nature of the city,
with the emphasis on their Castle (the Nagoya Joo in the centre).
Lily must be their city flower, and the water below represented the Nagoya
Harbor. Interestingly enough, and it is the main reason I took this
picture, was that for some plates, there was an engrave of "N"-- north
on the top of the inner ring, and this particularly plate was actually
pointing to the North. I made a point to check out other plates,
and so far, to my surprise, most of them were pointing roughly towards
the northern end-- not exactly, but close.
