March 9 marks both Miku Hatsune Day and Zaku Day, making it the perfect occasion for this special collaboration. The Real Grade Zaku II is now presented in Miku Hatsune’s signature color scheme, blending the world of Miku and Gundam in a striking new way.
This exclusive release comes with specially designed realistic decals, adding a unique futuristic aesthetic that complements Miku's digital theme. With amazing articulation and mechanical detailing, this Zaku II delivers both dynamic posing and impressive color separation, a must-have for fans of both Zaku and Miku!
March 9 is recognized as both Zaku Day and Miku Hatsune Day due to the way the numbers 3 (san) and 9 (kyuu) can be read in Japanese.
Zaku Day (ザクの日) – In Japanese, "3" can be read as "za" (a stretch of "san"), and "9" can be read as "ku", forming "Zaku" (ザク), the iconic mass-production mobile suit from the Gundam series. This play on numbers has led fans to unofficially celebrate March 9 as Zaku Day, often showcasing custom builds and tributes to the mobile suit.
Miku Hatsune Day (ミクの日) – Similarly, "3" (mi) and "9" (ku) can also be read as "Miku", making it a natural fit for Miku Hatsune, the beloved Vocaloid. As a result, March 9 has become an unofficial celebration of the virtual singer, with fans creating artwork, music, and special events in her honor.
Since both Zaku and Miku share the same number-based wordplay, the two fandoms have occasionally overlapped, leading to fun collaborations like the RG 1/144 Miku Hatsune’s Zaku II.
