If possible, it would be Good if APNIC could also make contact with the rightful owners of the following additional 3 Japanese blocks,
Because whois contact information is, seemingly by acquisition and relocation, obsolete, it should be impossible for APNIC to do so.

I tried to make contact myself with the legit owners of all of the above, but found it to be quite difficult. The registered owner of the first one appears to have gone into hiding on a remote island someplace.
From whois information: remarks: reg-date: 1993-03-22 notify: tmiyoko@gaijin.co.jp mnt-by: MNT-ERX-CROSFIELDELE-NON-JP last-modified: 2008-09-04T07:31:15Z I guess CROSFIELDELE is Japanese branch of: https://en.wikipedia.org/wiki/Crosfield_Electronics The firm was eventually taken over by Fujifilm Japan and named Fujifilm Electronic Imaging, now FFEI Ltd. following a management buy-out in 2008.[1] though, according to: https://www.ffei.co.uk/about-ffei-design-and-manufacture-digital-inkjet/ MBO was in 2006. In the page, we can also confirm that FFEI was crosfield until 1997.
Making contact with the legitimate owners of the other two blocks, both of which belong to Japanese corporations that are still very much alive, was rather difficult also, because I am only a stupid gaijin, and don't speak a word of Japanese.
Both relocated. I send queries to the current contact points. Maybe, blocks with stale contact information are attacked. Masataka Ohta
