View source for Impacts of COVID-19 Pandemic

This page describes the '''effects of COVID-19 Pandemic on 48 Groups and Sakamichi Series.''' 

==Overview==
[[Wikipedia:COVID-19|COVID-19]] has impacted the majority of the entertainment world, 48g included. Most of the groups have had to close their theaters temporarily, pause or modify their handshakes, and postpone releases and events. Some groups even underwent major changes to their line-up.

The first impact of COVID-19 was with in the [[SNH48 Group]] on January-February 2020 when the first quarantines in the world (specifically in China's main cities) were announced, the theaters closed, as well as their group activities were cancelled. Over time, they began to do only online performance and later they gradually opened their theaters without an audience and then with the public, except for the [[BEJ48 Theater]] which was permanently closed. At same time [[AKB48 Team SH]] also was impacted, the shonichi of their 1st stage being postponed. 

Then it spread throughout the world, with Japan being one of the first countries affected. This directly affected the [[AKB48 Group]], who were forced to cancel performances at their theaters. 

Due to the largest wave of infections in Mainland China history, during December 2022 all AKB48 Team SH and SNH48 Group performances were canceled until further notice.

On October 28th, her [[Shiraishi Mai Graduation Concert ~Always Beside You~|graduation concert]] was held virtually, with an estimated viewership of 680,000.

On February 23rd 2021, the [[Nogizaka46 9th YEAR BIRTHDAY LIVE]] was held, although originally scheduled to have a live audience in attendance, due to COVID-19 restrictions, it was later changed to an online concert. Later in March and May, each generation had their own BIRTHDAY LIVE online concert, with the 2nd Generation Live being [[Hori Miona]]'s graduation concert. In late May, the group held the [[Nogizaka46 Under Live 2021]] online as well, being the last live for [[Ito Junna]] and [[Watanabe Miria]].

On June 22nd and 23rd 2021, the group resumed in-person concerts with [[Sa~ Yu~ Ready? Sayuringo Gundan Live／Matsumura Sayuri Graduation Concert]]. The live was also streamed online.

From July to August 2021, the group went on their yearly summer tour, [[Nogizaka46 Summer National Tour 2021]]. Both dates in Fukuoka (August 21 & 22) were streamed online as it was the 10th Anniversary of the group's formation and [[Ozono Momoko]]'s graduation concert, respectively. However, their final tour dates at Tokyo Dome (September 8 & 9) were postponed due to increased COVID-19 cases. This was to be [[Takayama Kazumi]]'s graduation concert, so her graduation was postponed indefinitely.

===[[Keyakizaka46]] → [[Sakurazaka46]]===
----
====Releases====
The group's documentary, [[Bokutachi no Uso to Shinjitsu: Documentary of Keyakizaka46]] was originally scheduled to release on April 3, 2020. Due to the COVID-19 Pandemic, the release date was postponed until September 6, 2020. The documentary was later released on Blu-Ray and DVD on February 3, 2021.

====Events====
On April 15th and 15th, 2020, the planned "Keyakizaka46 4th YEAR ANNIVERSARY LIVE" was cancelled due to the COVID-19 Pandemic. Later on May 29th, the planned [[Keyaki Republic]] concert for 2020 was also cancelled. However, on July 16th the group held their first online concert with [[KEYAKIZAKA46 Live Online, but with YOU!]] where the group announced that they would be rebranding from Keyakizaka46. The estimated total number of viewers reached 300,000. On September 27th, the group held a second online live, [[KEYAKIZAKA46 Live Online, AEON CARD with YOU!]].

On October 12th and 13th, 2020, the group held their final live as Keyakizaka46, [[Keyakizaka46 THE LAST LIVE]], as an online broadcast. In the finale of the second day, they premiered their first song as Sakurazaka46, [[Nobody's fault (Song)|Nobody's fault]]. The estimated total number of viewers for both days was 570,000.

On December 8th, 2020, Sakurazaka46 held their first live with their new name: [[Sakurazaka46 Debut Countdown Live!!]] The live had no in-person audience, and was instead broadcast live in theaters across Japan. Following the release of their 1st and 2nd Singles, the group held mini online lives where they performed each song on the respective single.

In June 2021, Sakurazaka46 resumed in-person concerts with [[BACKS LIVE!!]] and later with [[W-KEYAKI FES. 2021]]. However due to the pandemic, the group continues to have online viewing capabilities for these concerts. The in-person concerts also require the audience members to wear a mask at all times and prohibit shouting and fan-calls.

On July 22nd and 24th, 2022, Sakurazaka46 was scheduled to hold two concerts as part of [[W-KEYAKI FES. 2022]]. However, several members tested positive for COVID-19 days before the event, and the concerts were cancelled. Fans were refunded for their tickets. The hashtag <small>#いつもありがとう櫻坂46</small> (“Thank you always Sakurazaka46”) trended on Twitter in response to the cancellation. Sakurazaka46’s sister group [[Hinatazaka46]] continued to perform at the event. 

Additionally, Sakurazaka46 has not had any in-person handshake events for their 1st to 3rd Singles. Instead, the group has opted for online "Meet & Greets <small>(ミート&グリート)</small>" through Fortune Music's "fortune meets" app.
