They are also known as the fireworks makers that mesmerized many with their power of expression that extends beyond a given worldview’s themes and imagery. Their time-difference fireworks that emits strong light has special characteristics to them; their formation and ability to manipulate the space upon buursting,  gives a boost to the entertainment level of any fireworks musical. With their ability to flexibly adapt to the requirements on-site, they have achieved numerous successes in choreography, as well as fireworks launches. The name of Marugo is so well-known out of Japan, that overseas fireworks experts actually make the trip to Japan just to view their fireworks displays.
“>With Satoshi Saiki as the main hanabi artisan, whose constant stance is to pursue “even better hanabi”, Marugo and its hanabi artisans are the best pick of people who will make STAR ISLAND an even more attractive entertainment event.
As mentioned before, Marugo, Beniya Aoki and Marutamaya Ogatsu all share the same passion and sentiments for Japanese fireworks. We believe that having all 3 companies involved will bring the spectacle to greater heights.
