Japan Billboard Hot 100 Highlights — August 2026

#BillboardJapan #Jpop #JapanMusic

August 2026 produced four different weekly leaders on the Billboard Japan Hot 100: timelesz opened the month with “消えない花火,” TWS followed with “SODA SODA,” EBiDAN pushed the already-charting “Yes! 東京” from #13 to #1, and TOMORROW X TOGETHER closed the month with “セツナハナビ (Setsuna Hanabi).” The turnover at the summit was substantial, but the month also contained a remarkably stable second layer: Mrs. GREEN APPLE’s “Brand New” remained between #3 and #5 throughout all four charts, M!LK’s “好きすぎて滅!” stayed inside the Top 10, and Sakanaction’s “夜の踊り子” continued to hold upper-chart positions. Billboard Japan’s component data also shows that August’s leaders arrived through different combinations of physical sales, downloads, radio, streaming, and video consumption rather than through one uniform formula. With the weekly #1 changing every time while several established songs remained consistently competitive underneath, was August’s most important story really who reached the summit—or who refused to leave the upper chart?

Top Songs That Dominated August 2026

“消えない花火” — timelesz

timelesz began August at #1 with “消えない花火,” earning 9,059 overall points on the August 5 chart. According to Billboard Japan, the single sold 424,416 copies during the tracking period and ranked #1 in CD sales, #3 in downloads, and #15 in radio. It also represented the group’s first overall Billboard Japan Hot 100 #1 under the timelesz name.

“SODA SODA” — TWS

TWS debuted directly at #1 on August 12 with “SODA SODA,” recording 8,916 overall points. Billboard Japan reported 307,037 CD sales, enough for #2 in that metric, while the track also ranked #2 on radio. The song was the title track of TWS’s Japanese second single and gave the group its second Hot 100 #1 in Japan.

“Yes! 東京” — EBiDAN

EBiDAN delivered August’s largest weekly point total when “Yes! 東京” jumped from #13 to #1 on August 19 with 15,706 points. Billboard Japan reported 1,313,739 CD sales alongside a #3 streaming placement. The song had already been charting before August, so it does not qualify for the new-entry table below, but its mid-month surge made it impossible to exclude from August’s dominant-song discussion.

“セツナハナビ (Setsuna Hanabi)” — TOMORROW X TOGETHER

TOMORROW X TOGETHER closed the month with a direct #1 debut. “セツナハナビ (Setsuna Hanabi)” earned 11,446 overall points and led both radio and downloads, while selling 420,878 physical copies and ranking #2 in CD sales. It also reached #13 in streaming and #21 in video, giving the release one of August’s most broadly distributed metric profiles.

“Brand New” — Mrs. GREEN APPLE

Mrs. GREEN APPLE never reached #1 with “Brand New” during August, but its consistency was notable: #4 on August 5, #4 on August 12, #3 on August 19, and #5 on August 26. Billboard Japan repeatedly reported the song at or near the top of the streaming ranking, making it one of the clearest examples of durable consumption beneath the rotating weekly leaders.

Releases That Charted — August 2026

The following songs made their first Billboard Japan Hot 100 appearance on an August 2026 chart. Release dates come from Billboard Japan’s accompanying Hot 100 reporting and release information; peak positions are restricted to the four charts published in August.

Release Date	Artist	Song Title	Peak Position in August
July 29, 2026	timelesz	消えない花火	#1
July 29, 2026	ILLIT feat. JISOO, MOMOKA of HANA	I Got Your Back	#2
August 4, 2026	TWS	SODA SODA	#1
August 5, 2026	ME:I	花咲く道	#2
August 5, 2026	≒JOY	サマーツインテール	#3
August 12, 2026	Hearts2Hearts	ICONIC HEART	#2
August 19, 2026	TOMORROW X TOGETHER	セツナハナビ (Setsuna Hanabi)	#1
August 19, 2026	AKB48	好きish	#2

The late-July release dates of “消えない花火” and “I Got Your Back” are intentional: both songs made their first Hot 100 appearance on the August 5 chart, so they qualify as August chart entrants even though their commercial releases occurred shortly before the calendar month began.

Observations

• Four different songs occupied #1 across the four August charts.
• EBiDAN recorded the highest weekly point total among those leaders, with 15,706 points.
• Three of the four August leaders—timelesz, TWS, and TOMORROW X TOGETHER—reached #1 on their first chart week.
• EBiDAN took the opposite route, rising from #13 to #1.
• Mrs. GREEN APPLE’s “Brand New” remained between #3 and #5 throughout August.
• M!LK’s “好きすぎて滅!” ranked #8, #7, #4, and #6 across the four weeks.
• Sakanaction’s “夜の踊り子” remained between #8 and #12 throughout the month.
• August showed several high physical-sales weeks, including EBiDAN at 1,313,739 copies, AKB48 at 765,977, timelesz at 424,416, TOMORROW X TOGETHER at 420,878, and TWS at 307,037.

Spotlight on August 2026 Chart Entries

“消えない花火” — timelesz

Released on July 29, “消えない花火” is a single title track and the theme song for the animated film 君と花火と約束と, in which timelesz member Shori Sato has his first lead role in an animated feature. Its opening Hot 100 performance was led particularly by physical sales: Billboard Japan recorded 424,416 copies, placing it #1 in CD sales, alongside #3 in downloads and #15 in radio. That combination carried the track directly to #1 overall on August 5.

Its subsequent movement was considerably steeper: the track ranked #22 on August 12, #64 on August 19, and #83 on August 26. The strategic takeaway is therefore two-sided. The release achieved maximum launch visibility and secured a milestone first Hot 100 #1 for timelesz, but the August data also shows that its peak was substantially more concentrated around the first tracking week than the month’s most durable streaming-led songs.

“I Got Your Back” — ILLIT feat. JISOO, MOMOKA of HANA

“I Got Your Back” was issued as the title song of ILLIT’s Japanese second single, with HANA members JISOO and MOMOKA participating as featured performers and lyricists. Billboard Japan reports that the song was released digitally in advance on July 26 before the CD arrived on July 29. It entered the August 5 Hot 100 at #2 after recording 85,475 physical sales, while also placing #3 on radio and #15 in video.

The song then moved to #15, #26, and #27 through the remaining August charts. That is a significant decline from its debut peak, but unlike some release-week spikes, it remained inside the Top 30 for the full month. Strategically, the collaboration connected ILLIT’s Japanese release cycle with HANA’s audience while producing stronger chart retention than a one-week-only physical-sales surge.

“SODA SODA” — TWS

TWS released “SODA SODA” on August 4 as the title track of its Japanese second single. Billboard Japan recorded 307,037 physical copies during the first tracking period, placing it #2 in CD sales, while radio also ranked the song #2. Those two strong metrics helped deliver 8,916 overall points and an immediate Hot 100 #1.

The chart result also carried broader career significance: Billboard Japan noted that this was TWS’s second Hot 100 #1 in Japan following its Japanese debut song “はじめまして.” The strategic message is clear—the group demonstrated that its initial Japanese chart success could be repeated rather than remaining a one-release event. Within August, however, the month’s constant turnover meant that even a #1 launch existed in an exceptionally competitive weekly environment.

“花咲く道” — ME:I

ME:I’s “花咲く道” was released on August 5 as the title track of the group’s fourth single. It entered the Hot 100 at #2 with 8,093 overall points. According to Billboard Japan, the release sold 146,201 physical copies, placing #3 in CD sales, while also taking #4 in radio and #7 in downloads.

That combination gave ME:I one of the strongest new entries of the August 12 chart, but the later August data did not show comparable upper-chart retention; the song reappeared at #100 on August 26. Its strategic importance therefore lies primarily in the scale of the opening week. The chart demonstrates that ME:I could generate a Top 2 composite result, but August’s broader market rewarded songs capable of maintaining streaming or multi-metric activity after the initial sales period.

“サマーツインテール” — ≒JOY

≒JOY released its fifth single “サマーツインテール” on August 5. The track debuted at #3 on the Hot 100 with 6,832 points. Billboard Japan reported 371,043 physical copies—the group’s largest first-week total to that point—and the song ranked #1 in the sales metric.

Its later movement was much less stable, falling to #69 on August 19 and #98 on August 26. The performance therefore represents a textbook contrast between strong fandom-driven purchasing and broader chart retention. The #3 peak was substantial, but the trajectory illustrates why a high sales rank and a sustained Hot 100 presence are not interchangeable measures of success.

“ICONIC HEART” — Hearts2Hearts

“ICONIC HEART” marked Hearts2Hearts’ Japanese debut single and was released on August 12. It entered the August 19 Hot 100 directly at #2 with 6,983 overall points. Billboard Japan reported 65,176 physical sales and a #1 radio position, giving a new group a notably broad introduction to the Japanese market.

One week later, the track moved to #28. That decline confirms that the debut was front-loaded, but the radio leadership is strategically significant: unlike a release relying exclusively on CD sales, “ICONIC HEART” also had strong broadcast exposure. For a Japanese debut, the #2 Hot 100 entry established immediate awareness even if the second-week position showed how difficult it was to sustain the opening scale.

“セツナハナビ (Setsuna Hanabi)” — TOMORROW X TOGETHER

Released on August 19 as the title track of TOMORROW X TOGETHER’s Japanese fifth single, “セツナハナビ (Setsuna Hanabi)” delivered one of August’s most balanced #1 performances. Billboard Japan reported 420,878 CD sales, placing #2 in that metric, while the song simultaneously ranked #1 in downloads, #1 in radio, #13 in streaming, and #21 in video. It entered the composite Hot 100 at #1 with 11,446 points.

This matters strategically because its result was not built on one category alone. The track showed substantial purchasing strength while also leading two non-sales metrics and appearing meaningfully in streaming. Among August’s direct #1 debuts, it therefore had one of the clearest multi-channel performance profiles.

“好きish” — AKB48

AKB48 released “好きish” on August 19 as the title track of the group’s 68th single. It debuted at #2 on the August 26 Hot 100 with 9,248 overall points. Billboard Japan reported 765,977 physical copies, the highest CD-sales total of the week and considerably more than the 420,878 copies recorded by the overall #1 song from TOMORROW X TOGETHER.

That contrast is particularly useful for understanding Billboard Japan’s methodology. AKB48 dominated physical sales yet placed #2 overall because the Hot 100 combines multiple consumption metrics. Strategically, “好きish” demonstrated the continuing commercial strength of AKB48’s physical-single model while also showing why raw CD volume alone does not automatically determine the composite chart winner.

Market Analysis

Stability vs Virality

August offered a sharp contrast between rotating weekly winners and persistent streaming-era performers. None of the four #1 songs repeated at the top, while Mrs. GREEN APPLE’s “Brand New” remained #4, #4, #3, and #5; M!LK’s “好きすぎて滅!” stayed #8, #7, #4, and #6; and Sakanaction’s “夜の踊り子” ranked #11, #12, #8, and #10. The month therefore supports a distinction between peak dominance and sustained chart strength: release weeks controlled #1, while a smaller group of established tracks repeatedly occupied the surrounding positions.

Media / Anime Influence

Media tie-ins were visibly present in August’s Hot 100. Billboard Japan identifies timelesz’s “消えない花火” as the theme for the animated film 君と花火と約束と, Spitz’s “見知らぬ糸” as the theme for TBS drama Tシャツが乾くまで, Kento Nakajima’s “鬼事” as the opening theme for season two of The Elusive Samurai, and Mrs. GREEN APPLE’s “Brand New” as a theme song for Spider-Man: Brand New Day. Media exposure did not create one uniform chart pattern, but tie-ins clearly contributed to the month’s mix of new entries and durable upper-chart songs.

Fanbase Economics

Physical purchasing remained highly influential but was not sufficient by itself to determine the overall winner. EBiDAN’s extraordinary 1,313,739-copy week coincided with #3 streaming and produced the month’s largest #1 total. By contrast, AKB48 sold 765,977 copies—August’s second-largest figure among the highlighted releases—yet finished #2 overall behind TOMORROW X TOGETHER, whose release combined strong sales with #1 positions in downloads and radio. Billboard Japan’s August data therefore demonstrates the continuing power of organized physical purchasing while also showing why multi-metric performance remains strategically important.

Final Take

August 2026 was a month in which reaching #1 and dominating the chart became increasingly separate ideas. timelesz, TWS, EBiDAN, and TOMORROW X TOGETHER each owned one weekly summit, yet Mrs. GREEN APPLE, M!LK, Sakanaction, ILLIT, and Kenshi Yonezu supplied much of the month’s continuity. Physical sales still generated enormous leverage—particularly for EBiDAN and AKB48—but the contrast between AKB48’s sales leadership and TOMORROW X TOGETHER’s composite #1 shows exactly why Billboard Japan’s multi-metric structure matters. August did not produce one uncontested song of the month; instead, it exposed the different economic models currently coexisting inside Japanese popular music. As release-week fandom power and sustained digital listening continue to compete, which one will define the next generation of Japan’s biggest hits?
