Super Mario Odyssey sold 511,625 copies during its first three days of release in Japan, according to the latest Famitsu numbers.
The numbers include both download card and Switch Super Mario Odyssey hardware bundles, but do not include download sales.
Switch hardware sales for the week were 133,000 units, which is nearly 5.6 times the 24,000 units sold the previous week. Super Mario Odyssey undoubtedly played a role in this boost.
Super Mario Odyssey launched worldwide for Switch on October 27.
