The title, released on July 23, 2026, topped the Japanese weekly software chart and led software sales for the period, according to the available weekly sales figures.
Sales snapshot and market context
"Sales data show that Splatoon Raiders moved 474,684 physical copies in Japan during its launch week," the weekly chart indicates, underscoring the title's strong physical-market performance.
The launch coincides with a strong hardware week for Nintendo: the Nintendo Switch 2 was the top-selling platform in Japan with 50,168 units sold during the same sales window.
Other notable software performers included Rhythm Heaven Groove (released July 2, 2026) which sold 78,355 units for a lifetime total of 674,592, and Tomodachi Life: Living the Dream (released April 16, 2026) which added 23,468 units to reach a lifetime of 1,500,025 copies.
Long-running Nintendo franchises also appeared in the top ten, with Mario Kart World (Switch 2) and Pokemon Pokopia contributing continued sales to their multi-million lifetime totals.
Hardware breakdown
The Switch 2’s weekly sales of 50,168 lift its lifetime total to 6,102,027 units in Japan.
Sony’s PlayStation 5 Digital Edition was second for the week with 8,512 units sold (1,370,791 lifetime).
Legacy Switch hardware remained in sales rotation: Switch Lite (3,771 weekly, 6,999,458 lifetime), Switch OLED Model (2,770 weekly, 9,612,780 lifetime), and the original Switch (626 weekly, 20,305,232 lifetime) all registered units.
Wider implications
The numbers reflect the continued strength of Nintendo-first franchises in Japan and the importance of strong physical launches for major first-party releases.
Splatoon Raiders’ opening-week figure places it among recent high-profile Nintendo debuts on the Switch 2 platform.
For developers and publishers, the week’s chart reiterates that hardware cycles and first-party IP remain key drivers of Japanese boxed-sales performance.
Weekly software and hardware totals were led by Splatoon Raiders and the Switch 2 respectively, while a mix of long-selling catalog titles and recent releases rounded out the top listings for the period.
