Debuting at No. 1 on the latest Billboard Japan Hot 100 dated Sept. 25 to Oct. 1 is “Shori No Gaika,” the first single by a six-member group called “Touken Danshi Formation of Mihotose.” The group’s name basically means “sword boys from Mihotose,” and the members are characters from the musical Mihotose No Komoriuta (“300-year lullaby”), the fourth stage production based on the incredibly popular Touken Ranbu video game that depicts Japanese swords as attractive young men.
The single sold 75,034 copies in its first week and came in at No. 1 for physical sales and look-ups, propelling it to the top spot. Devoted fans of the franchise have been mentioning the song in tweets (No. 5 for Twitter mentions) as well, and depending on how well the single continues to sell, it has enough momentum to stay in the top 10 for a while.
Namie Amuro, who landed 12 songs in last week’s Japan Hot 100 after announcing her retirement from show business in less than a year’s time, still has 6 songs on the tally with “Hero” at the highest at No. 11. The songs are mostly being driven by download points, and all 6 songs are in the top 25. The download rankings for each song are No. 1 for “Hero” (2016), No. 7 for “Love Story” (2012), No. 12 for “Can You Celebrate?”(1997), No. 18 for “Don’t Wanna Cry” (1996), No. 23 for “Baby Don’t Cry” (2009), and No. 24 for her latest single “Just You and I,” and she still has 13 songs in the top 100.
AAA’s new single “Life” rises from No. 8 to No. 5 on the Japan Hot 100 powered by downloads and streaming. Twitter mentions for the song have surged (No. 2 this week from No. 7 last week) and the CD will go on sale Oct. 18, which suggests that the track could continue to rise on the chart.
The digital-only collab single “Koi No Hajimari” by Leo Ieiri, Sakurako Ohara, and Sakura Fujiwara debuts at No. 9 this week, coming in at No. 2 for downloads, No. 3 for radio airplay, and No. 23 for Twitter mentions.
