Billboard Japan Hot Albums

The Billboard Japan Hot Albums, also referred to as Combined Albums, is the primary album record chart published by Billboard Japan. It is released weekly on Thursday in Japan Standard Time.

The Hot Albums was launched on the week dated June 4, 2015, with Superfly's White (2015) as the inaugural number one. It initially ranked albums based on a combination of physical sales, digital downloads, and PC look-ups, and was the only combined albums chart in Japan until the establishment of the Oricon Combined Albums Chart in December 2018. Since December 2024, the chart has been based on physical sales, digital downloads, and streaming; the look-up factor was removed after Billboard Japan became unable to collect such data from the provider since October 2022. Physical sales units are provided by SoundScan Japan, whereas GfK Japan tracks digital downloads from Amazon, iTunes, Mora, Mu-mo, and RecoChoku, with additional iTunes data courtesy of Luminate, and streaming from Amazon, Apple Music, and Spotify, etc. In June 2025, Billboard Japan introduced the recurrent rule for the Hot Albums, alongside the Japan Hot 100, applying to albums charting more than 26 weeks. It came into effect on the chart week of June 4.

The South Korean band Seventeen holds the record for most number ones on the chart with a total of 14. Hikaru Utada, who has topped the chart 11 times, holds the record for solo artists. For specific albums, Dreams Come True The Best! Watashi no Dorikamu (2015) by Dreams Come True has the record for most weeks at number ones on the chart, with seven, and Kana Nishino's Just Love (2016) has the most number ones as a solo album, with five. Back Number's Encore (2016) has the most total chart weeks with 319; Kenshi Yonezu with Yankee (2014), Dreams Come True with their aforementioned album, Yumi Matsutoya with Nihon no Koi to, Yuming to (2012), and Southern All Stars with Umi no Yeah!! (1998) are the only other artists to have albums surpass 200 weeks.
