Big Echo x Masashi Sada "Uta Goshuin Meguri" to be held from May 15 – Collect all 50 types by visiting Big Echo stores nationwide!

Daiichikosho Co., Ltd. (hereinafter referred to as "the Company") will collaborate with Masashi Sada, a leading Japanese singer-songwriter, to implement the "Uta Goshuin Meguri" starting May 15, 2026. Fifty Big Echo stores will present "Uta Goshuin" (song seals) with different popular karaoke song titles designed for each store. Masashi Sada released his new song "Kamisama no Iu Toori" (As God Says) in April. In May, he will release an album and simultaneously kick off the "Masashi Sada Concert Tour 2026 Kamisama no Iu Toori," which will visit 36 locations nationwide, starting May 15. The collaboration project with Big Echo will also begin simultaneously with the tour. Uta Goshuin is a popular Big Echo project that presents certificates designed with song titles, similar to the Goshuin (temple/shrine seals) received at temples and shrines. Previously, Uta Goshuin Meguri campaigns were held with THE ALFEE and EXILE, which were so well-received that many people visited multiple stores. This time, 50 popular karaoke songs by Masashi Sada have been selected, and different Uta Goshuin are prepared for each store, mainly at Big Echo locations near the tour venues. These are original designs incorporating handwritten titles by Masashi Sada himself, making them collectible items available only at Big Echo. Furthermore, the "Uta Goshuincho" (Uta Goshuin book) for collecting and pasting Uta Goshuin will be sold at merchandise booths at each venue of the "Masashi Sada Concert Tour 2026 Kamisama no Iu Toori" and on online shopping sites. Combining Uta Goshuin with the Uta Goshuincho allows for both the joy of collecting and the satisfaction of admiring them. The Company aims to promote visits to Big Echo and revitalize karaoke usage by actively developing collaborations with trending artists and works. ■ Big Echo x Masashi Sada "Uta Goshuin Meguri" Overview Implementation Period: May 15, 2026 (Fri) - December 6, 2026 (Sun) Participating Stores: 50 stores (target songs vary by store) *Participating stores may change during the period / Please check the national Uta Goshuin map in and the campaign page on the Big Echo official website for details.
