Their South American leg would be the final stops for JYJ's first worldwide Tour. On February 23, 2012, JYJ released a 90-minute film titled The Day in South Korea. It was a documentary film featuring their daily lives and dreams, and was screened for 4 days at Lotte Cinema‘s 17 major chain theatres across the country, drawing 24,000 fans. In June 2012, JYJ held the first ever large-scale international fan fair in South Korea. The "2012 JYJ Membership Week" was put together specifically as a gift for their fans, and fully funded by the members themselves in spite of numerous sponsorship offers. It was held for 4 days— from June 28 to July 1—at SETEC (Seoul Trade Exhibition & Conventions) at Hak Yeo Ul station and cost an estimated KRW 3.7 billion. The membership week included photographic and video-based exhibitions of the group, theatre screenings of The Day as well as two sets of fan meetings that invited over 15,000 Korean fans and 7,000 Japanese fans. The huge influx of foreigners was the largest for a single event, and generated great economic benefits for South Korea. JYJ's representative C-JeS Entertainment has announced that this Membership Week event will be held annually. In August 2012, JYJ released Mahalo, a premiere collection photobook with over 200 pages taken during their trip to Hawaii in December 2011. On February 25, 2013, JYJ performed a medley of hit songs from the '90s as well as their own songs at the 18th South Korean Presidential Inauguration Ceremony for the country's first female president Park Geun-hye, in front of an audience of 70,000 people. At the same time C-JeS Entertainment announced that the band would be able to perform at Tokyo Dome in Japan after a four-year hiatus due to their lawsuit with Avex Group. The band held a 3-day concert series titled "The Return of the JYJ" from April 2 to 4. As all 150,000 tickets were sold out, footage was released to 118 theatres across Japan in order to accommodate fans unable to obtain tickets for the concerts. In July 2014 the band released their first studio album in three years, Just Us. The band reached the music charts with the song, "Back Seat". 2018–present:
