Streaming took over the world as the main way of listening to music.
Japan is still changing in that direction, but streaming is the only distribution method growing in recent years.
Correlating with this developement, the RIAJ started its streaming certification chart in April 2020, also certifying all songs reaching a threshold before.
This is a thread to list all official streaming certifications made by the RIAJ.

Up to today (March 2024) twelve songs reached the highest certification Diamond for 500,000,000 streams:

Yoru ni kakeru - YOASOBI
Gunjo - YOASOBI

General information

What's RIAJ and this all about?

Spoiler:

The Recording Industry Association of Japan (RIAJ) is an industry trade group composed of Japanese corporations involved in the music industry.
It was founded in 1942 as the Japan Phonogram Record Cultural Association, and adopted its current name in 1969.
In 1989, the Recording Industry Association of Japan introduced the music recording certification systems.
It is awarded based on shipment figures of compact disc or cassette tape which was reported by record labels.

The RIAJ Streaming Certification system is a system to track the songs with highest streaming numbers in Japan.
RIAJ counts all streaming plattforms for their certifications and it's updated accordingly.
Full list consists of:
Amazon Music Prime、Amazon Music Unlimited、Apple Music、au Smartpass Premium Music, AWA、KKBOX、LINE MUSIC、Rakuten Music、Spotify、TOWER RECORDS MUSIC powered by レコチョク、YouTube Music、YouTube Music Premium.

Here's the monthly chart with all certifications: https://www.riaj.or.jp/f/data/cert/st.html.
This is where all certifications are listed and where I took my information from to make those lists following in this thread.

What are the certification thresholds?
There are five main ones:
Gold (ゴールド) (50,000,000 streams),
Platinum (プラチナ) (100,000,000 streams)
Double Platinum (ダブル・プラチナ) (200,000,000 streams)
Triple Platinum (トリプル・プラチナ) (300,000,000 streams)
Diamond (ダイヤモンド) (500,000,000 streams).

In December 2021 they adjusted the thresholds a bit and discarded the Silver one for 30,000,000 streams.
Streaming certifcations just start from Gold since then.
