Hana no Ko Lunlun: Konnichiwa Sakura no Kuni

Lunlun travels to Japan with Cateau and Nouveau to reunite with her friends Midori and Yoshio and admire the country's famous cherry blossoms. The visit takes a troubling turn when she sees pollution damaging the scenery she came to enjoy.

Togenishia and Yabouki soon make matters worse by targeting the blossoms themselves, threatening to strip the trees of their petals. Lunlun must protect the spring landscape and the people who cherish it, turning her journey through Japan into a fight to preserve a beauty that cannot survive without care.
