Overview
Adauser Mizca is a Japanese-language YouTube channel that retold crypto news for people who read Japanese rather than English. Its creator, who publishes under the pen name 渡辺水華 (Watanabe Mizuka), built each episode around an article from overseas that she had translated herself1. The channel has stopped uploading, so what is left is an archive rather than a running feed2.
Most of that archive follows Cardano, a public blockchain network. She worked through open letters and blog posts from Input Output Group and EMURGO, two of the organizations behind Cardano, alongside exchange notices and commentary from the crypto press3. Her own channel blurb sums the job up as mainly publishing video translations of overseas articles about crypto assets1.
Key Features
- Overseas crypto writing, retold in Japanese. The channel's stated format was video translation: take an article published in another language, then talk it through in Japanese for a local audience1.
- Cardano's founding organizations covered at the source. A joint open letter from Input Output Group and EMURGO to the Cardano community became a multi-part Japanese series, worked through in full rather than summarized second-hand3.
- Public thanks from EMURGO's Japanese account. EMURGO's Japanese-language account shared one of her Cardano translation videos and thanked her by name for the work4.
- A looser talk series beside the translations. A recurring strand she named つぶやきラジオ (Murmur Radio) mixed Cardano reading with everyday observation, and its title points at radio rather than video5.
- More than Cardano in the later years. The channel was not a Cardano-only feed across its whole run: later uploads widened into Japanese personal finance, including tax-free investment accounts and brokerage security notices6.
What to Expect
Everything on Adauser Mizca is Japanese, from the spoken narration to the titles and the descriptions, and the channel says plainly that it was made to carry overseas crypto articles to Japanese-speaking viewers1. Readers who do not know Japanese will usually find the underlying articles easier to reach in their original language.
The last stretch of uploads returned to Cardano and ADA subjects: Charles Hoskinson interviews, institutional money moving into ADA, and a demonstration pairing Cardano with Bitcoin2. That thread ran to the final video, so the Cardano identity holds even though the subject mix had widened along the way.
Adauser Mizca is no longer publishing2. Treat it as a back catalogue rather than a feed. Its worth is as a record of how English-language announcements from the Cardano ecosystem reached a Japanese-speaking audience, one translated article at a time, and it is not a place to look for ongoing news. Anyone who wants a channel that is still posting can start from the other Cardano YouTube channels in this directory.
