ayu's wikipedia page (EN)

[Katsuyuki012]

I was thinking about updating it because it barely mentioned anything she's done since her return in the career section. It's just kinda annoying getting all the sources, especially since there is a lack of articles (sources like Arama etc don't count) that talk about her new stuff. It's mostly press releases, but that should be enough for a mention in her article. I'll have a look.
I've been keeping her releases up-to-date but I ran into some issues regarding sources and notability etc, so I didn't feel like working on the main article, as well.

Just checked the page and someone did update it to mention the recent singles, which is something! I think, for a while, DaD was the last release to be mentioned in the main article.
So I'd say that, as of right now, most of the important stuff is mentioned at least, but it's missing stuff like her embarking on a proper tour again, her participating in the 17Live thing or her Bilibili Macro Link performance.
Maybe I'll add that sometime soon...

"The discography is completely outdated."
Do you mean the discography section that only includes her albums? Or the stuff that's mentioned in the "Life and career" section? If it's the former, that is actually as updated as it can be. They only include studio albums there, after all. For some time they had three categories there which listed all her albums, EPs & compilations but it got changed back.

Also, anyone can edit a Wikipedia page, as long as it's not protected. Entering the info of your sources correctly might be a tad confusing in the beginning, especially if you use Japanese articles.
