By approximately 2008-2009, her online presence — including fan blogs, her agency’s profile, and sales pages for her DVDs — vanished without a trace. This is known in idol fandom as sakura saku (the cherry blossoms fall). There was no farewell DVD, no public announcement, and no social media cry (as social media was in its infancy).
