Here’s what I got from Google Translate when I asked it to translate this page from Japanese to English:
Summer vacation concert performance schedule
July 22nd (day) 11 o’clock in the morning & 2 o’clock in the afternoon Tokyo opera city concert hole
July 26th (the wood) 2 o’clock in the afternoon the Chiba prefecture cultural center
July 28th (the Saturday) 11 o’clock in the morning & 2 o’clock in the afternoon the sonic city hole (Omiya)
July 29th (day) 11 o’clock in the morning & 2 o’clock in the afternoon you see as Yokohama everyone, the leprosy hole
July 31st (the fire) 2 o’clock in the afternoon the Kamakura art mansion (the large boat)
August 3rd (the gold) 2 o’clock in the afternoon the Narashino cultural hole
August 4th (the Saturday) 11 o’clock in the morning & 2 o’clock in the afternoon you see as Yokohama everyone, the leprosy hole
August 5th (day) 11 o’clock in the morning & 2 o’clock in the afternoon Tokyo art theater (Ikebukuro)
August 7th (the fire) 2 o’clock in the afternoon the [miyuza] Kawasaki symphony hole
— The japanese filling: Concert information > July
That almost makes sense — it’s a concert schedule. I have no idea what a “leprosy hole” is supposed to be.
