About haju: | ハユ

haju:harmonics, handled @hajuharmonics on YouTube, is a Japanese virtual singer channel with about 18,900 subscribers and roughly 87 uploads. The channel posts short vocal covers of popular Japanese songs and original releases, most under a minute, with the video of the Ember original song reaching 1.57 million views. Based on channel data, the audience appears to be mainly Japanese-speaking viewers aged 18 to 34, though this is an estimate.

The channel has no sponsorship disclosures in its recent uploads. Its median view count is about 1,900 per video, so a sponsored integration is estimated at $150 to $250 per video, which works out to a CPM of roughly $4 to $8 per 1,000 median views for Shorts-heavy channels. That is below the $10 to $30 CPM typical for paid ads, and the Shorts-based pricing favors short, low-cost campaigns.

Brands seeking Japanese music or anime audiences should consider this channel, particularly for music releases or anime-linked promotions. Upload activity has stopped in the last year, so confirm recent availability before booking.
