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”.
From a country who strips one’s citizenship if one gets another (Japan) and following the court cases to allow dual citizenship I say the motivation for dual citizenship is not because so that they can work for their origin country. Duties and rights of citizen work in both ways.
From what I can tell the main motivation for citizenship is a) directly related restriction in job market ( eg. operating license for the field) or b) to legalize and secure their right to stay with their family members. Immigrants have financially attached to the country of living and their decision is often practical, and their vote is dependent on whether the policy is beneficial to them, like people with single citizenship.
It needs proper background check for sure, but the argument of foreign interference is fear mongering and often xenophobic imo.
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.
