Translation fails for some locations which have names that have been translated from another language into Japanese.
For example:
アボッツフォード空港 (Abbotsford Airport)
アンガルシー (Anglesey)
コンスタンツァ (Constanta)
エスペランス空港 (Esperance Airport)
There are many other examples of this behaviour. By turning on debugging it looks like it could be an issue with the tokenizer or token features. I have very little knowledge of Japanese or how this translation works so I can't provide much more insight.
Thanks!
