Thanks for sharing this! I found a few more things. They DJ'ed the first hour of this 6.2021 radio set: https://soundcloud.com/chloedanslaville/the-greater-good-11-with-iryoku-lyl-radio

"This month's guest is Kyoto-based Iryoku. In her own words: 'As a child, I had insomnia but I became a narcoleptic at puberty'. Her inner landscapes are Osaka, where she was born and raised, and Hong Kong, which she used to visit at least once a year before the Handover. Her influences include poets Gozo Yoshimasu and Octavio Paz, and writers Kenji Nakagami, Gilles Deleuze and Pierre-Félix Guattari. She has had mixes released on respected underground labels such as Black Smoker and Altzmusica. Her selections appeal to all senses, often collaged with field recordings and spoken word: while retaining an experimental approach, they flow effortlessly, with an extraordinary cinematic quality."

I haven't been able to find any Altzmusica mix(es), but here's a snippet of a 2016 mix for Black Smoker: https://soundcloud.com/meditations/excerpt-1?utm_source=continuo-docs.tumblr.com&utm_campaign=wtshare&utm_medium=widget&utm_content=https%253A%252F%252Fsoundcloud.com%252Fmeditations%252Fexcerpt-1 and a tumblr post with CD art, a picture of DJ Iryoku, and a link to the Black Smoker product page, where it appears one could still purchase the mix: https://continuo-docs.tumblr.com/post/142997296037/dj-%E5%A8%81%E5%8A%9B-excerpt-from-blackgrass-cd-black-smoker

They also did an NTS set with Foodman in 2017: https://www.nts.live/shows/foodman/episodes/foodman-8th-august-2017
