About STRUM-CH
STRUM-CH is the YouTube channel of Kazuki Kuwahara, designer for the Japanese leather brand STRUM, according to his brand's website. The channel posts short vertical clips and occasional longer explainers on leather jacket construction, aging, rain care, and styling, with a Japanese-speaking audience. Viewer demographics are estimates based on the channel's content and language, not verified platform analytics.
The channel has about 16,700 subscribers and a median of around 6,100 views per video, with roughly six uploads in the last 90 days. Its output is mostly Shorts, so sponsored integrations are priced at $4 to $8 per 1,000 median views, which works out to $150 to $250 per video. That compares with a typical paid-ad CPM of $10 to $30, so the cost per view is comparable.
The channel suits brands selling leather care, outerwear, or motorcycle apparel to Japanese menswear buyers. It is a poor fit for English-language campaigns.
