if you've payed attention to japanese sales you would know that first day sales are generally 2/3 of the sales for an entire week. For example VF5 sold 32,500 on day 1 and 50,000 for the week, Fire Emblem for wii sold 50,000 on day 1, and 74,000 for the week. 120,000 sounds like a huge number to sell in 1 day to us, but in Japan it happens all the time. Second and third week sales will only be a fraction of that.
