About California Base
California Base is a Japanese YouTube channel run by Style Ai Home, the home and exterior construction arm of Tobi Aida in Chigasaki, Kanagawa. The channel posts on-site construction work, Japanese-language explainers on home design, insulation, flooring, doors and exterior work, and build-along videos of its "California Base" model homes. Uploads run at about 50 videos a year, with roughly half of them under a minute. Recent titles include a concrete floor pour, a gate build and a salon renovation. The channel publishes Shorts alongside long-form videos.
The audience is estimated rather than measured. Viewers are likely Japanese adults planning a home build or renovation, along with trade-curious viewers. With about 1,460 subscribers and a 755-view median, reach is modest but the audience is specific. Sponsored integrations are priced at $150 to $250 per video, which works out to roughly $20 to $35 CPM on median views for long-form, compared with $10 to $30 CPM for typical paid ads.
This channel suits Japanese tool, building material and home-goods brands that want a trade-focused viewer. It is less suited to mass consumer campaigns.
