Okufu Letter
The monthly deep dive
The public catalog on this site is a dated snapshot. The Okufu Letter is the paid PDF that reads the same sold history as a market report: where prices moved, which titles to watch, and how book, obi, flyer, and both compare.
What each issue covers
- Market line - watchlist pulse, series breadth, biggest movers, tier dashboard, object-class charts.
- Focus desk - every issue includes the three S+ titles (Dragon Ball, One Piece, Demon Slayer), plus a rotating set of lower-tier titles with median ± σ and unveiled charts.
- Takeaways - short conclusions you can price against.
Facsimile sample
A short FACSIMILE PDF with invented figures. Same layout language as the paid letter, reduced so you can see the reading experience without live tape.
