Konnichiwa Cazaust-san!
My name is Nangi. I live in Hyogo that is next prefecture of Osaka, and I have lived in Osaka in the past. I reply your question as much as possible.
Osaka is the second city in Japan. Of course the biggest city is Tokyo. Osaka is the first capital city at ancient times and there is a lot of old temples.
There is an international airport, Shinkansen(special express) station, many railroad and subway stations. Osaka's traffic is very conveniently.
There is a lot of warmhearted people. But most of all people has curiosity and impertinent. Japanese are very well mannered but Osaka people is the worst ill mannered.
Australia consulate is in Osaka.

Ugly and Beautiful. The center of city is a street lined with office buildings and is a beautiful(and safe) place. The periphery of middle city is the shopping area and is not beautiful(and not safe) place. Some of shopping area is very ugly and dangerous. Japan is very peaceful country but there is a lot of larcenist in Osaka.
Some other areas I have read how there are lovely walking trails, or nice beaches etc but I havent found much information about Osaka.
There is not a beache in Osaka city because the coast of Osaka is factory district.
How far is it to Kobe by train or car?
Kobe is about 50 minutes from Higashi Osaka by train. I think 30 minutes by car.
I know that Kobe is a man made area and that is why when the earthquake struck there it was so devastating. It Osaka on man made land?
The west area is a man made land.
