The difficulty of problems A-F will not be changed. The range of difficulty of new problem Gs will be wider, some of them can be as easy as current problem Gs, while others can be as hard as current problem Exs. Please check the point values of each contest for more accurate estimation of difficulties. We are looking forward to your participation!

We have invited top-runners of AtCoder Race Ranking 2019-2022 to Tokyo. We will combine the results of the two contests to decide on the champion. The score of the participant is calculated as (score of Day1) + (score of Day2) + (the number of Advancements to Finals). The time penalties are also summed. You will see this combined score in the standings during the contest. Considering that the special rules will affect strategies of participants, the Finals itself is unrated. Note that, unlike other onsite competitions, there's no freeze in the contest. Mirror contests don't have special rules, so they are just two independent rated contests. They happen at the same time as the Finals (=13:00 in UTC+9), so they are much earlier than usual AtCoder contests. We are looking forward to your participation!
