RMJ

RMJ is the short name of Raumanmeren Juhannus, the beach weekend at Otanlahden Rantapuisto in Rauma, Finland, by the sea. In October 2026 it still stood that the summer of 2026 did not take place. The meeting from Thursday 19 to Saturday 21 June 2025 was the twentieth, with thousands of people on the shore. Jonna Pihkala, head of production, built a disco container called Loop, a flea point and games on the beach. Tinze presents the Ananas Stage.

The first time was in 1999. The founder, the Rauma native, is Riku Räsänen. In 2003 the three-day sum ran around 90,000 and in 2005 it was 99,000. YleX and Radiomafia, its predecessor, recorded concerts from 2002 to 2004. In 2007 the owner passed to SK Festivals Oy, a subsidiary of SK Ravintolat Oy. That year Pamela Anderson was there and there were three deaths. In 2008 the place moved to Kirjurinluoto, in Pori, to the Pori Delta Arena, and the name stayed RMJ. In 2009 SK Entertainment Group let go of the majority. Räsänen, Jyrki Kangas, that same house, Local Crew and Toni Järvinen came back, and the name became RMJ Party Camp. In 2010 there was a smaller date in Rauma called RMJ Unajassa. 2011 closed that stretch.

The return to Otanlahti was the solstice of 2016, with David Guetta, Jason Derulo and Nero on the bill and a target of 30,000 over two days. In 2017 there were three days, 50,000 tickets, and Pendulum, David Hasselhoff, Shaggy and The Rasmus played. In 2020 and 2021 there was no date, because of the pandemic. In 2018 Nelonen Media Live ran the programme and Suomen Elämyspalvelu Oy, Räsänen's company, ran the grounds and the lodging.

The concert is at Urheilukatu 22, 26100 Rauma. The temporary unattended parking is on Sinkokatu, with the sign RMJ Parkkialue, and the car stays off the streets next door. The tent is on Suvitie and Poroholman lomakeskus is at Poroholmantie 8. The bus station at Tallikedonkatu 13 is about 2 kilometres away. The official taxi is Keskustaksi, with a stop on Urheilukatu in front of the main gate, and there is another temporary stop on Raumanmerenkatu. The official tickets are Tiketti and Lippupiste. The grounds are K-18. At the door only a card is valid. The code is read electronically and a lost ticket is not replaced. The prices were 172 euros for three days, 155 for two and 104 for one, plus a group ticket for more than five. A tent at Rantaleirintä and a cabin at Poroholma sold together on Tiketti.

Ares had the album APATHIA out in January. Vitunleija ran a pop-up clothing shop built for the festival.

On Thursday 19 June 2025 Sanni played at Otanlahden Rantapuisto. Doors were at 17:15 and the schedule at 19:00. The title is Sit ku mä oon vapaa. The tour is called Kesä 2025. The summer of 2026 did not take place: production costs had risen and the concept of then did not pay. Ticket sales for 2026 never opened. A later date stays open, with no plan. Those prices were for the meeting of 19 to 21 June 2025, and on Thursday the doors opened at 17:15.
