no, it is not an error, as this network entry really didn't provide an abuse address. Heck, they really didn't provide an address at all:

No match!!

looking up the JP00010080 AS number (well, JP number, as it isn't really an AS number) I get:

                                apply@iij.ad.jp

So nic-sec[at]iij.ad.jp would be the address to complain to, and I personally would add a comment to hostmaster[at]nic.ad.jp letting them know that the above entry has no abuse address listed and is spamming
