SMAP has already outsold ayumi on the 1st day by almost 2.5 : 1 so I don't think it's possible for ASB to get #1 anymore
Also , GIFT of SMAP is their 20th album overall & being released in 4 editions ... they're not known as (still) the best selling Johnny's of all time for nothing
1) SMAP - GIFT of SMAP ; 85,362
2) ayumi - A SUMMER BEST ; 31,803
