- Yokohama City will hold YOKOHAMA GREEN CHALLENGE WEEK inside the GREEN×EXPO 2027 venue from Wednesday 26 May to Tuesday 1 June 2027. The city is the organiser, and the week has four main parts: a parade, a butterfly-shaped symbol object, live music and a “park” area.
- Greenroom Co. and Sony Music Group will cooperate on the live music, described as concerts by professional artists.
- Greenroom started GREENROOM FESTIVAL in Yokohama in 2005 and now holds it at Yokohama Red Brick Warehouse.
- Sony Music Group has led CENTRAL MUSIC & ENTERTAINMENT FESTIVAL since 2025, using several Yokohama venues including K-Arena Yokohama and the Red Brick Warehouse.
- The artists, performance dates and how to watch will be announced later. Prices and the exact location inside the venue are not stated.
Our take
The dates of the week and its four parts were already in the city’s 29 September announcement. At that point the music was described only as “live music”; this is the first time the cooperating companies have been named.
Both companies have run music festivals in Yokohama. On the Sony side there is an earlier link: on 24 August Sony Music Entertainment signed a sponsorship contract with the city pavilion, lending exhibits related to the same festival. One company’s festival is now tied to both the city’s pavilion and the city’s event week.
What matters to visitors is what it takes to watch. The release places the concerts inside the Expo venue, so we think an admission ticket will be the minimum. Whether seats are reserved, drawn by lottery or open to anyone passing by will change how you plan the day. Only two of the seven days, 29 and 30 May, fall on a weekend, so the day-by-day line-up will decide which date to pick.
Tips for visitors
- The week runs from Wednesday 26 May to Tuesday 1 June 2027. The line-up will appear on the city’s YOKOHAMA GREEN CHALLENGE WEEK site and in its press releases.
- There is no need to buy a dated ticket for this week before the line-up is out. Ticket types are in our ticket guide.
- The other parts of the week are in our report on the 29 September announcements.
Our take
In September the city only said the week would include live music. Now the two companies cooperating on it are named, and both already run music festivals in Yokohama. The artists, the dates of each show and whether anything beyond Expo admission is needed are still to come.
