a) Allows multiple business activities: A general work visa only allows you to engage in the business listed on the visa, but a Highly Skilled Professional visa allows you to engage in multiple businesses, such as running a business while engaging in academic research at a university.
b) 5-year residence period: Generally, the duration of a work visa ranges from 3 months to 5 years. The Immigration Bureau will determine the duration of each visa based on your residence record, company size and operating conditions, etc. However, Highly Skilled Professional visas are always issued for 5 years and can be extended later.
c) Relaxation of permanent residence permit requirements related to residence: If the spouse is non-Japanese, foreigners must have lived in Japan for 10 years before they can apply for a permanent residence permit, and they must hold a work visa for 5 years. However, under the Highly Skilled Professional visa system, as long as you score 80 points or above, you can apply for a permanent residence permit after maintaining work for one year; with a score of 70 points or above, you can apply for a permanent residence permit after maintaining work for 3 years, so it is regarded as a shortcut to obtain a permanent residence permit.
d) Employment of spouse: Spouses with general work visas do not have employment qualifications and need to apply for a "permit for activities outside the qualifications" to be allowed to work no more than 28 hours a week; or meet the "education", "technology or humanistic knowledge or international business” visa academic qualifications and work experience requirements before you can engage in full-time employment. However, spouses holding Highly Skilled Professional visas can still obtain visas to work full-time even if they do not meet the academic qualifications, work experience and other requirements.
e) Parents are allowed to live together under certain conditions: Highly Skilled Professional visa holders, if their family income exceeds JPY8,000,000, can use the reason of taking care of children under 7 years old, or taking care of the pregnant visa holder/spouse, may apply for parents of one side to live together in Japan.
f) Allowing domestic helpers to live with them under certain conditions: Japan originally only allowed foreigners engaged in "business management" or "law/accounting" to live with overseas domestic helpers. In some cases, holders of Highly Skilled Professional visas can apply for domestic helpers to live in Japan together. 1) If the family income exceeds JPY10,000,000, they can pay the helper a monthly salary of JPY200,000 or more, and the helper has already paid for this before coming to Japan. If the family has been working overseas for more than one year, it can continue to hire and apply to live in Japan; or 2) If the family income exceeds JPY10,000,000, it can support the monthly salary of a helper of JPY200,000 or more, and there are children under 13 years old in the family who need care. You can apply to bring the same overseas domestic helper to live with you in Japan.
g) Priority processing of entry/residence procedures: first-time application, approval time is about 10 days; application for extension of period of stay or change of status of residence, etc., processing time is about 5 days.
