Kamuhakari

Kamuhakari (神議) is the name of the tenth month in the traditional Japanese calendar, when the country's gods gather at the Izumo Shrine. It is also referred to as Kannazuki (神無月, lit: "the month when there are no gods") by those not in Izumo or Kamiarizuki (神在月, lit: "the month when the gods are present") by those who are in Izumo.

In-universe, it is treated as a ceremony where gods create fated ties. It has been held at least 2,600 times in the past ; the 2,6XXth ceremony begins in chapter 58.

Notably, during this time, most gods are absent from their shrines, including those guarding the sealed hafuri vessel. Only a few gods stay behind in order to watch over the country in the others' absence. Normally, Ebisu is one of these gods, but in this case, he wishes to form favorable ties since the economy is still in a recession; he also has his shinki performing 24-hour land purification to protect the Near Shore while he's gone.

Invitations
Only gods who are recognized as legitimate and who are loyal to Heaven are allowed to attend. The invitation is a slip of paper, where gods mark "attending" or "not attending" and sign their name. To send their answer to Heaven, Yato is shown folding the invitation into a paper airplane and throwing it to the sky.

It seems that it is customary for a god to bring only their guidepost with them. However, Hiyori is able to accompany Yato under the guise of a retainer, suggesting that this may also be common practice.

Activities
Gods' popularity rankings among humans are announced at Kamuhakari, consisting of first through third place place and a "rookie of the year" award.
 * 1st place: Ebisu
 * 2nd place: Inari
 * 3rd place: Tenjin
 * Rookie of the year: Stationmaster Tama

Afterwards, gods partake in a "matchmaking" event. In order to form a more harmonious world, gods weave favorable ties between humans, which bring peace and abundance to the Near Shore. They do so by tying ema, each representing a single human, together with cords.
