AJX pilots are NOT employed in Japan. They are employed by contract companies, based in places like,USA, Isle of Man and, Vanuatu. The contract companies then second the pilots to AJX.
In the eyes of the Japanese Authorities, the pilots are deemed to be foreign based crew operating into and out of Japan, as a result, the crew enter/exit on a shorepass or passport.
The AJX pilots enjoy NO protection under Japanese employment law, have no access to Japanese social benefits. They are also not liable for Tax in Japan. There are a few who have obtained residence in Japan and they ARE liable for Japanese tax.
Be very careful saying the pilots pay no tax. Tax liability is individual and is influenced by country of domicile etc. Most of the pilots actually DO pay income tax, some are exempt by the laws of their country of domicile.
As far as taxation goes, VERY IMPORTANT, get advice from a tax professional in your country of residence as far as AJX tax goes, this forum is not the place to get it.
AJX pilots are employed differently to other airlines in Japan, eg Peachie, Banilla, Jetstar, etc. AJX pilots are not allowed to conduct domestic operations, all flights have to be international flights.
Lastly, please stop referring to AJX as ANA, it is a subsidiary of ANA but the pilots do not enjoy the advantages of ANA pilots, in fact, they are often reminded they are NOT ANA, except when it suits the company, of course!
