About

What this is

Ticket sales come in phases — fanclub presale, a separate window for overseas fans, lotteries in Japan, general sale. Each vendor only posts its own, and the window overseas fans need is often a different day. We gather them all and hand you one calendar.

What this is not

This will not help you buy faster. No macros, no bots, no automated purchasing. We tell you when sales open and send you to the official vendor to buy there yourself.

Where the dates come from

We read official vendor notices, notice when one changes, and pull out the sale phases. Anything we are not sure about waits for a person instead of going up.

What we do and don't take

We only read sources that allow it, we never repost a notice's text — just the facts and a link — and we say who we are in our requests.

Sometimes we will be wrong

Vendors move dates, and a wrong time here is the thing we least want. Every event page has a report button that needs no account. That is the most useful thing you can send us.
