Oshi-Katsu Chronicle 2017: Insta-Bae and TikTok, Kemono Friends, TWICE's Japan Debut, and the Rise of VTubers
In 2017, “insta-bae” (Instagram-worthy) was chosen as a grand prize winner in the Buzzword of the Year awards, referring to photos or places that look striking when posted on Instagram. In autumn, the short-form video app TikTok also launched in Japan, expanding the spaces where people shared what they loved through photos and short clips.
The anime Kemono Friends grew from shared theories and reactions on social media into collaborations with real zoos, while in music TWICE made its Japan debut and Namie Amuro announced her retirement for the following year as her all-time best album Finally earned a double-million shipment certification. The year also saw the launch of the Nintendo Switch console and the rise of “Virtual YouTubers (VTubers)” led by Kizuna AI.
Kemono Friends: From Reacting to the Anime to Visiting the Zoo
Aired late at night from January to March, the TV anime Kemono Friends followed the journey across the vast “Japari Park” zoo of Serval—an animal transformed into a human girl known as a “Friend”—and Kaban, a girl who does not know what kind of creature she is. Mysteries hidden behind director Tatsuki’s gentle dialogue and affirming catchphrases like “Sugoi!” (“Amazing!”) and “Tanoshii!” (“Fun!”) caught fire on Twitter and Niconico Video, pushing free streams of Episode 1 past 10 million views.

On February 8, the opening theme song “Youkoso Japari Park e” (“Welcome to Japari Park”), written and composed by Masayoshi Oishi and sung by Doubutsu Biscuits x PPP, was released. Praise from musician Gen Hoshino on his radio show helped propel the song to music-show appearances and long-running CD sales. Victor’s record of the release (in Japanese)
After the broadcast ended, from April 22, a collaboration event was held at Tobu Zoo in Saitama Prefecture, placing character panels around the real animal exhibits and playing in-park announcements by the voice actors.
