Japan is home to countless beloved characters, from Hello Kitty to Pikachu. But have you heard of “Yuru-Chara”, Japan’s unique local mascots?
The term “Yuru-Chara” comes from “yurui mascot character”—loosely meaning “laid-back mascots.” These characters have become popular across Japan in recent years, serving as regional PR ambassadors. Their designs often highlight local specialties, traditions, or landmarks, making them both cute and meaningful.
One of the most famous Yuru-Chara is Kumamon from Kumamoto Prefecture. But this time, we’ll shine a spotlight on the mascots of Yamanashi Prefecture, home to the iconic Mt. Fuji.
In particular, we’ll introduce the mascots of the Northern Area of Yamanashi, which includes Kofu City (the prefectural capital), as well as Hokuto City, Kai City, Nirasaki City, Minami-Alps City, Chuo City, and Showa Town. Each has its own mascot full of regional character and charm!

By around 2031, the Linear Chuo Shinkansen (maglev train) is scheduled to open at Yamanashi Station, located between Kofu City and Chuo City. With this exciting development on the horizon, the region is attracting even more attention.
Now, let’s meet the adorable Yuru-Chara mascots of Yamanashi’s Northern Area!
Hokuto City | Yatsugatake Happī
Yatsugatake Happī is the official mascot of Hokuto City, designed as a cheerful bee that flies energetically around the Yatsugatake area. One of its most charming features is that it wears a different regional flower necklace each day, symbolizing the area’s rich nature and seasonal beauty.
Hokuto City is especially famous for its sunflowers, and every year hosts the popular Sunflower Festival, where vast fields of sunflowers bloom in full glory. Happī reflects this vibrant local identity and adds extra charm to the region.
Although updates on its official X account have paused since 2019, many locals and fans continue to support Happī, hoping to see the mascot actively return in the future.

Kofu City | Takeda Haru-kun
Takeda Haru-kun is the mascot of Kofu City, designed as a 9-year-old boy who dreams of becoming a samurai one day. Full of youthful spirit, he especially loves Hōtō, Yamanashi’s signature noodle dish.
His name comes from “Harunobu”, the name once taken by the legendary warlord Takeda Shingen when he came of age. This gives Haru-kun a strong historical connection to Kofu, which is deeply tied to the Takeda clan’s legacy.
Although Haru-kun is a rather low-profile mascot for now, many look forward to seeing him grow into a strong and dependable figure, much like Takeda Shingen himself.
