What's an OshiroBots gojōin
(See #02 Takamatsu Castle in this book for full details.) 「城郭合体オシロボッツ」 is a MIXI ANIME franchise launched December 2022 that re-imagines Japanese castles as transforming-robot mecha. As of 2024 the lineup includes 10+ castles. Collaborative gojōin (300 yen each) are sold at each castle's gift shop and were initially distributed at the Shiro EXPO 2023 event.
The Himeji OshiroBot's "white heron" theme
The Himeji OshiroBot is designed around the castle's poetic nickname 白鷺城 (Shirasagi-jō / "White Heron Castle"):
- White-armored body echoing the castle's brilliant white-plastered walls
- Wing-like outboard structures that resemble a heron taking flight (the way the connected sub-keeps fan out from the main keep is often described as bird-like)
- Heron-headed helmet with a beak silhouette — the Mecha's most distinctive visual element
The red silhouette of the shirasagi behind the brush calligraphy reinforces this theme, even though the actual castle exterior is pure white — the red silhouette is a graphic-design choice for the gojōin print.
The Himeji-Okayama black-and-white pair
Himeji is 白鷺城 (White Heron Castle) — and Okayama, ~80 km east, is 烏城 (U-jō / Crow Castle) for its black-lacquered exterior. The two castles are deliberately discussed as a black-and-white pair in tourism materials, reflecting their opposed visual identities + their shared OshiroBots collaboration. The user's collection of both #03 (Okayama OshiroBots) and #13 (Himeji OshiroBots) in this book is a deliberate set.
