The Japanese word for "Hornet" is suzumebachi 雀蜂.
- Vespinae vs. Waspsuzumebachi 雀蜂 refers to the subfamily Vespinae. All Vespinae are Wasps, so you can always translate suzumebachi スズメバチ to "Wasp," but some Wasps aren't Vespinae, so you can't always translate "Wasp" to suzumebachi スズメバチ.
The word "Hornet" katakanized would be hōnetto ホーネット.
Beware: some kanji that are difficult to handwrite are easy to type on the computer, which may skew the usage statistics.
