- If the title has official English localized name, use that. Meaning take the official English name over the Japanese name were available. Both should be synonyms.
If I'm not mistaken, the series "Hataraku Saibou" has an official English title: "Cells at Work!" So, can we create the tag cells-at-work and make hataraku-saibou its synonym? I think this would be in line with the above quoted policy.
