About まさゆき / 【IT系】株式会社Decryption

Masayuki (@masayuki-decryption) runs a Japanese-language YouTube channel focused on certification exam preparation. The channel posts long audio-only glossary videos, such as 2級建築施工管理技士 and 宅建 term lists, with narrated terms and explanations meant for listening during commutes and chores. Uploads run at about 50 a year, and the channel also links to a related study website, according to website excerpts.

Viewers are estimated to be Japanese adults in their twenties and thirties preparing for licensing exams in construction, real estate, accounting, care work and similar fields. Audience figures are estimates only, since the channel has a small subscriber base and no published audience data. The channel's median of 54 views per video is low, so reach per video is limited.

A sponsored integration is priced at $150 to $250 per video. That works out to about $20 to $35 per 1,000 median views, which is a higher CPM than the typical $10 to $30 for paid ads. Brands selling study tools, exam prep courses or career learning products to Japanese candidates should consider booking this creator.
