<a href="/artist/6745279/daoko/chart">DAOKO</a> x <a href="/artist/6677778/kenshi-yonezu/chart">Kenshi Yonezu</a>'s long-lasting hit "Uchiage Hanabi" returns to No. 1 on the latest Billboard Japan Hot 100 chart dated Sept. 18 to 24, still faring well in most metrics besides radio airplay to accumulate points in a balanced way.

But after ruling downloads, streaming and video views for five consecutive weeks, the track gives way to a couple of singles from the past for reasons we'll get into below, and the Japan Hot 100 top 10 has shifted significantly since last week.

The song at No. 2 on the Japan Hot 100 this week is "Dancing Hero" by Yoko Oginome. It's the Japanese-language cover of Angie Gold's 1985 disco tune "Eat You Up" that was also released that same year. The cover became a huge hit when it was released and is still one of Oginome's best-known songs, and its sudden resurgence after 32 years takes some explaining of recent events in Japan.

"Dancing Hero" beat "Uchiage Hanabi" in video views, because some dance videos using the song have garnered over 8.7 million views combined (twice the figure for "Uchiage Hanabi"). The girls of Osaka's Tomioka High School dance club came in second place at a national competition this year with their routine, donning outrageous '80s fashion -- long spirally hair with poofy bangs and gaudy shoulder-padded mini-dresses probably borrowed from their moms -- and the videos have gone viral, thanks in part to the endorsement by the singer herself.

Popular female comedian Nora Hirano also uses the song in her routine that pokes fun of the "bubbly" late '80s to early '90s Japan, and the song is quickly becoming an upbeat symbol of fast times that only people aged 40-something and up remember nowadays.

Meanwhile, the iconic songstress Namie Amuro broke the Japanese internet on Sept. 20 when she announced on her official website that she would retire from show business in less than a year. Devastated fans are apparently downloading her past catalog in droves, and she currently has 17 songs in the top 100 in downloads including her hit "Hero" from last year at No. 1.

The massive uptick in download points has powered 12 of her old songs into the Japan Hot 100. Eleven of her past albums including Best Fiction from 2008 have also returned to the top 100 in downloads, reflecting the phenomenal impact of the news of her retirement. This phenomenon is expected to continue for a while, similar to when the iconic boy band SMAP broke up last year.
