Watanabe Mayu [Synchro Tokimeki] 1st Day Sales

Watanabe Mayu's debut single [Synchro Tokimeki] released yesterday, just barely breaking the 50k mark.

It was a tough fight between her and Johnny's Yamashita Tomohisa, but the Mayuwotas managed to ger her in the lead for now. The exact sales is 50,145, close to what Itano Tomomi sold on her first day for her single Fui ni.

I was actually expecting more than that, maybe rivaling Tomochin's Dear J 1st day sales of 86k. After all  it's Mayuyu's pictures that sell the highest in Yahoo Auctions. Nevertheless it is a good start, almost managing to outsell Warota's Kibou Sanmyaku's 55k 1st day.

So if we use the sales trend of Fui ni and Kibou Sanmyaku, we can approximate that the first week sales will be around 90k. But will it be enough to ward Yamapi off?

Side note: Why does Oricon do that for the covers? It's not like they don't have the covers on their database http://www.oricon.co.jp/prof/artist/478717/products/music/951909/1/
