inconel

I don't know where you get the information tho, it's factually false.

Japanese have have /h/, /ç/, /ɸ/ consonants in ハ行 (written as ha - hi - fu or hu -he - ho but pronounced differently). The consonant /ɸ/ is generally transcribed as f in alphabet.

フ(f+u) is the only letter that pronaunce /ɸ/ in regular ハ行, but ファ行 (f + other vowels) indicates sounds with /ɸ/.

Transcription of wifi in Japanese is ワイファイ, not ワイハイ.

It's just how they word layoff and severance package. In Japan voluntary resignation can be also entitled for severance package depending roles/duration of employment, and this gives larger package than regular voluntary resignation is entitled to, to make them resign "voluntary".
