x -> 1 -> 1 Kanjani∞ (Aoppana) - 104,797 + 49,044 = 153,841
Note: Numbers in copies, all versions included.
For comparison (as of this year's):
Ai deshita。 - 103,158 + 75,452 = 178,610
ER - 172,299 + 72,812 = 245,111
Well it dropped a lot, under 50k even! No doubt because of the heavy purchasing on the first day. Also, I've read that some stores are already out of stock since yesterday, and based on experience, the re-stocking will only occur on Friday nights and Saturdays, so we can expect the numbers continue to drop.
Compared to their other singles from last year though, Aoppana has already done better:
Tsubusa ni Koi (1st week) - 152,859
365 Nichi Kazoku (1st week) - 158,141
My Home (1st week) - 158,060
T.W.L/Yellow Pansy Street (2 days) - 84,325 + 46,587 = 130,912 (1st week: 200,816)
So I hope, it's still enough to make it to 200k in the first week.
