Continuing from last week's tally, the latest Billboard Japan Hot 100 ranking dated Jan. 1 to 7 reflects the impact of 2017 year-end live-music specials, with long-running hit songs by artists who performed in the 68th Annual Kohaku Uta Gassen music program on New Year's Eve dominating the top 20.

This phenomenon occurred partly due to the fact that physical sales were relatively slow during this chart week and songs that rack up points through the digital metrics of the chart's measurement performed particularly well.

The song at No. 1 this week is "Hero" by the Japanese R&B songstress <a href="/music/Namie-Amuro">Namie Amuro</a>, whose highly anticipated final Kohaku performance was the peak of last year's program, hitting an incredible 48.4 percent in viewership ratings. The NHK Summer Olympics and Paralympics theme song from 2016 came in at No. 1 for downloads and streaming, and also showed strength in other metrics such as radio airplay (No. 7) and Twitter mentions (No. 16).

Ten songs boosted by Kohaku performances charted in this week's top 20, with singer-songwriter Pistol Takehara's "Yo, Sokono Wakaino" making the biggest leap, rising 60-15. The song came in at No. 8 for radio, No. 11 for downloads, and No. 16 for streaming, clearly displaying the far-reaching influence of the prestigious year-end extravaganza. Whether or not the song holds onto its current position like <a href="/music/Keyakizaka46">Keyakizaka46</a> did last year after charting under similar circumstances remains to be seen.

Another notable event that catapulted old songs back onto the Japan Hot 100 this week was the first-ever regular TV broadcast of Makoto Shinkai's animated blockbuster Your Name on Jan. 3. The band <a href="/music/RADWIMPS">RADWIMPS</a> wrote the music for this movie and four songs from the soundtrack -- "Nandemonaiya" (No. 32), "Sparkle" (No. 35), "Zenzenzense" (No. 36) and "Yumetoro" (No. 98) -- returned to this week's tally, powered mainly by downloads, video views and Twitter mentions. 

The Billboard Japan Hot 100 combines physical and digital sales, radio airplay, Twitter mentions, YouTube and GYAO! video views, Gracenote look-ups and audio streams from Apple Music, AWA, Google Play Music, KKBOK, LINE MUSIC, Rakuten Music, Recochoku provided by Gfk Japan, as well as streaming counts based on lyrics displayed on PetitLyrics.
