By linking with the official Wonderia mobile application, visitors can collect creatures, natural elements, and even scenes from the city of Yokohama as cards. Each card contains one of over 100 original “Wonderia Tips” written specifically for this facility, offering enjoyable and accessible knowledge about living organisms and natural phenomena.

The Tale of Azai Nagamasa and His Family
Studio ONI has produced a hand-drawn Japanese ink painting animation titled
“The Tale of Azai Nagamasa and His Family”
as a satellite exhibition work for the NHK Taiga Drama Toyotomi Brothers (BROTHERS IN ARMS).
From February 1, 2026, the film is now on permanent public display at the mini theater of “Gi to Kizuna-kan (Hall of Loyalty and Bonds),” a newly opened cultural facility in Nagahama City, Shiga Prefecture, Japan.
NHK Taiga Dramas are long-running historical television series produced by Japan’s national public broadcaster, NHK, and are regarded as one of the most influential forms of historical storytelling in Japanese popular culture.
This work focuses on Azai Nagamasa, a Sengoku-period warlord of 16th-century Japan, his wife Oichi (sister of the famous warlord Oda Nobunaga), and their three daughters, who later became key historical figures through marriage into powerful ruling families.
Nagahama City is the region where the Azai clan lived, fought, and built their legacy, making it a place deeply connected to their history.
It is a great honor for us to contribute an official work connected to such a historic television series and to present it in the very land where these historical figures once lived and loved.
If you have the opportunity to visit Japan, we warmly invite you to experience the film in Nagahama.
