In English: (There aren’t many good resources on Yukiko in English, but I’ve collected what I can. If there's any I'm missing, don’t be afraid to contact me!)

Kayo Kyoku Plus: While not about Yukiko Okada specifically, if you have an interest in Japanese music from the 70s and 80s this is definitely worth checking out as it's the #1 English language resource on Shouwa-era music. This blog has been active for many years, and the wealth of information contained on the site is simply stunning. Highly recommended for fans of Yukiko, or Japanese music in general.

The Suicide of Yukiko Okada: Japanese youth and the Yukko syndrome: A very interesting, informative article about the Yukko Syndrome that followed Yukiko's death. Notable for being written close to the time of her death (July 1986), which makes this article unique amongst English-language coverage of Yukiko Okada.

Kanashii Yokan: The Life and Legacy of Yukiko Okada: This is an extremely important piece of work in terms of increasing knowledge of Yukiko amongst English speakers, and for many fans, this is how they first learned of her. It’s a shame it was taken off Youtube, since this is a truly monumental series. A huge amount of work and research has clearly gone into this highly engaging documentary series. However, I will caution anyone who wants to watch it, as it very prominently shows colour photographs of Yukiko Okada’s dead body (pictures that genuinely ran in many of Japan's sensationalist newspapers and magazines, sometimes on the cover.)

In Japanese: (you can use Google Translate to navigate)

ユッコスマイルをもう一度！: The definative and perhaps longest-running Yukiko Okada fansite, in operation since 1997. A great resource for information, and has some interesting interviews transcribed. Many of the sites in the Links section are dead, but you can look them up on Web Archive to find a wealth of lost late 90s Yukiko-centred websites.

かのん: An indispensable site for Yukiko fans, and a must-visit if you have any interest in her. Contains many rare pieces of Yukiko material, including scans of biography manga and the fanclub pamphlet (given how expensive materials related to Yukiko's fanclub are these days, these are particuarly valuable), as well as some exclusive photos. This is a truly amazing resource, and is highly recommended if you have any familiarity with Japanese.

Yukiko☆Fan: A newer site than most, this has quickly risen to be one of the truly great Yukiko Okada sites. This site is a full database of every TV show and radio show Yukiko appeared in, every location Yukiko performed or visited and every award she won. Much of this information is based on the site’s highly accurate, in-depth schedule that collates information from various sources. (Much of my work on the schedule is shamelessly copied from this site.) This is a monumental piece of research, and is an indispensable resource for Yukiko fans interested in her day-to-day activities. More information is constantly being added, so this is a site to keep an eye on.

Yukko in Swiss: Switzerland Travel Guide: A must-visit if you're planning on visiting Switzerland. The site lists the exact locations Yukiko visited while shooting the 'Yukiko in Switzerland' videos, so you can plan your Yukiko Okada inspired Swiss holiday.

ネットで集めた岡田有希子: My primary resource when researching the Yukiko Okada schedule. A great site for those wanting a timeline of Yukiko’s life, and an in-depth look at her day-to-day schedule.

In Korean: (machine-translated)

namu.wiki: Owing to the recent boom in popularity of retro Japanese music in South Korea, Yukiko Okada’s page on NamuWiki is quite in-depth, and has a lot of information and anecdotes that are hard to find elsewhere. While an entertaining read, I will caution that much of the information is hearsay, rumours, or just outright lies. Unless it’s corroborated elsewhere, take what you read here with a grain of salt.
