entry, I translated the sentence
Saitama Prefecture borders Tokyo on the north.One of the editors asked if the meaning of my English wasn't the opposite of the Japanese; that is, he suggested that my English seemed to imply that Saitama Prefecture is south of Tokyo. (Saitama is in fact north of Tokyo.)
It turns out that the construction "X borders Y on the [compass direction]" is ambiguous, as shown by these citations from the Web:
William Henry and Isabella spent many happy summer holidays at Kenora, Ontario, which borders Manitoba on the East.I changed my translation to "Saitama Prefecture is Tokyo's neighbor to the north."
