During my travel to Japan I watched a concert of this band in the pictures below. It was softrock in Japanese.
I really like the sound but do not know the name of the band or songs. It was close to Himeji castle I believe.
That's not a concert of a band but a performance played by samurai costume players. The names on the banners are all Mōri clan members; a sengoku daimyōMōri Motonari, his sons, his daughter and her husband.
