The billing date is the first of each month, and 1,500 yen is drawn from the bank account. Tally last month’s viewing and it averages forty minutes; bought one-off, that volume would have topped 3,000 yen. Sometimes the charge continues because cancellation was forgotten, sometimes deliberately because the maths favours it.

Gekkaku-uri (月額販売, monthly subscription sales) is the general term for the sales form in which a fixed monthly fee is paid continuously, granting access during that period to all or most of a creator’s content. The counter-concept to one-off sales, it is the core model of the modern creator-economy erotica on myfans, OnlyFans and Fantia.

Lineage and types

The monthly model inherits the old “flat contract” of magazine annual subscriptions, cable television, and monthly adult-video rental membership. On the internet, the 2000s paid AV sites (all-you-can-watch at roughly 3,000 to 5,000 yen a month) were the forerunner, and later FANZA and H!NEXT flat-rate services developed this line.

The OnlyFans, Patreon, FANBOX, Fantia and myfans services that emerged in the late 2010s added “directly supporting an individual creator”. The monthly fee goes not to a single maker or major platform but to a particular creator. Fees mostly fall in the 1,000-to-3,000-yen range, and subscribing to several creators at once is ordinary.

Difference from one-off sales

Where one-off sales sell ownership of a content unit (or indefinite viewing rights), monthly sales sell time-bounded access rights. Nothing is owned; stop subscribing and viewing ends.

The seller’s economics differ too. One-off sales tie revenue directly to a new release’s quality, while monthly sales fix monthly revenue by member count and churn. A hundred members at 1,500 yen yields 150,000 yen a month; a thousand, 1.5 million, a simple multiplication. In return, the operator owes a duty to keep updating content so members do not want to leave: several photo posts a week, several videos a month, occasional live streams and DM replies are effectively forced, a labour intensity specific to individual operation unlike studio production.

Hybrid design

Most monthly platforms adopt a hybrid of monthly and one-off sales. myfans allows one-off charges for individual posts alongside multi-tier monthly plans, so even a member can buy certain high-priced videos separately. OnlyFans’s pay-per-view sells limited videos individually to members by DM, charging a few to tens of dollars on top of the monthly fee. Fantia combines fan-club tiers with one-off sales of individual works, supporting doujin creators in running both steady monthly income and per-release sales.

Structure and psychology of reception

Monthly sales lower the buyer’s psychological cost below one-off sales. The transaction friction of deciding “do I buy this” for each work disappears, normalising into a fixed 1,500-yen monthly outlay, a “sunk-cost continuation”. Having paid once, the subscription auto-renews even in months one does not watch, and the decision to cancel meets a light psychological resistance.

Monthly sales also carry the identity of “being an enclosed member”. Where the platform displays a member number and tenure, a history of “supporting for over half a year” or “cumulative spend over 100,000 yen” becomes visible, strengthening attachment and the motive to keep paying, making cancellation harder.

Churn and operating sustainability

The core metric of a monthly business is churn. Above roughly 10 percent monthly churn, member count tends into net decline; held below 5 percent, long-term growth is in view. Measures to lower churn include keeping update frequency and quality up, enriching upper-tier perks (limited lives, DM replies, meet-up priority), and re-join campaigns at month’s end, methods established in older subscription services and applied to individual operation.
