At JOINUS, for two days on Saturday, May 30, and Sunday, May 31, we have prepared an event titled 'GREEN JOINUS Festa' where you can experience SDGs. The venue, the JOINUS rooftop 'JOINUS Forest Sculpture Park,' will host the 'JOINUS Ennichi,' where you can engage with SDGs in a fun way. By presenting a receipt for a purchase of 1,000 yen or more (tax included) from within the JOINUS building, you can participate in two of your favorite games from yo-yo fishing, shooting, and ring toss. Also held at the same time is the 'Disaster Prevention Riddle Solving,' where you can challenge riddles to learn necessary actions and wisdom for disaster preparedness! The first 300 participants each day will receive an 'Irregular Baumkuchen from Muji.' Stores with ethical initiatives such as Ethical-sea, Lush, and Parts Club will gather to sell items and hold workshops.

Furthermore, we will also be holding a value-packed trade-in campaign where you can bring in your unwanted bags and receive a 500 yen coupon usable at JOINUS. This is a limited-time chance to get a 500 yen coupon while contributing to reuse!

Why not take this opportunity to casually participate in SDGs initiatives along with your shopping and dining at JOINUS?
