Both AS lack an "aut-num" object in JPNIC, which is why there is no parseable information for them at hand in there. Not sure where RIPEstat gets their description from...
Anyways, ARIN, LACNIC and a better approach to missing data is on my list for next week. I'll see what we can to then.
AS names (the holder's name) shown on RIPEstat come from the CIDR report https://www.cidr-report.org/as2.0/ according to RIPE NCC's reply.
Maybe this is a one for all solution.
Since you apparently don't like this data source and I always thought RIPEstat has pretty good data quality: Would you mind sharing your opinion on this?
