English Translation

The Japanese and English say the same thing, but it doesn’t seem true? Geography of Japan - Wikipedia. I wonder what the source for this sentence is.
Take a look at the page of the original source on Tatoeba. The sentence is tagged as “false” statement.
If you need a sentence reflecting the reality, use the following pair instead:
日本は南北に連なった列島であり、山と急流が多く、平地が少ない。(pron. にほんは / なんぼくに / つらなった / れっとうであり、やまと / きゅうりゅうが / おおく、へいちが / すくない)
The Japanese Archipelago across from South to North consist of many mountains and steep streams with limited flatlands.
