Zaiko documents ticket access controls, not concert attendance

The setup

Zaiko is the ticketing and paid-livestream platform that Japanese VTuber agencies, music labels and event promoters use to sell access to concerts and shows, both in person and online. Its own organizer-facing pages and its public homepage, as retrieved on 16 September 2026, describe a company identified as Zaiko K.K. that states it has operated for 7+ years and hosted 80,000+ events. This entry documents what those pages state about how a ticketed livestream is actually built and protected, not which specific VTuber concerts used the service beyond what an event's own page says.

What the documents show

The organizer pages describe three things plainly. First, ticket types: an organizer can create free, paid or mixed tickets, and can bundle single shows into multi-day festival or pass formats. Second, access control: a ticket page can be restricted with hidden links, password protection or fan-club-only availability, and a high-demand release can run as an apply-to-buy lottery with automated intake and winner notification. Third, fees: the platform lets an organizer choose whether the platform fee is absorbed, passed to the attendee, or shared, with a payout preview shown before the event goes live. The homepage adds that an event's archive is often kept viewable for an extended period after the broadcast ends, though neither page states one universal replay window, since that appears to be an organizer setting rather than a platform-wide rule.

The craft

For a production team, these are the levers that turn a single livestream into a ticketed event: whether a show is open to anyone with a link, gated behind payment, or limited to a fan-club tier; who absorbs the transaction fee; and how long a paying fan can rewatch it afterward. None of this is unique to VTubing, but it underlies almost every ticketed VTuber concert or paid members-only stream not run natively on YouTube or Twitch. Choosing an apply-to-buy lottery over first-come sales trades speed for fairness at scale, a trade-off the documentation frames around high-demand releases.

Keeping the creator in control

The access-control options matter for a performer's say over who sees a show and on what terms: a password-gated or fan-club-only stream keeps an event out of casual public view, distinct from a fully open premiere. The fee-sharing choice is a direct, disclosed decision about how much of a ticket price reaches the production versus the platform. This is an editorial reading beyond what Zaiko's own pages claim: a team's choice of ticketing platform and access settings is itself a statement about who an event is really for.

• Which access control best matches this show: an open link, a password, or fan-club-only availability?
• Who is meant to absorb the platform fee, and is that shown to the buyer before purchase?
• How long will the archive stay watchable, and is that window stated anywhere a fan can check?

Read together, Zaiko's own pages describe a configurable back end for ticketed streaming rather than a single fixed product, which is exactly why the same platform can host a solo apply-to-buy fan meeting and a mass-market festival broadcast without changing tools.
