Torre starred in the first half and there was a debut for Julian Araujo
Franck Kessie and Eric Garcia were on target as Barcelona beat Vissel Kobe 2-0 in Tokyo on Tuesday.
Both goals came in three first-half minutes as Barca officially brought the curtain down on their season after LaLiga ended on Sunday.
Former Barca player Andres Iniesta played his final game for Vissel Kobe before embarking on a new adventure elsewhere -- he has not yet revealed where -- but it was Pablo Torre who stole the show in the first half.
The youngster hit the post early on before creating the opening goal for Kessie in the 16th minute with a fine pass which split the Kobe defence open.
Torre is also known as a dead ball specialist and that proved so when his delivery was headed in by Garcia as Barça doubled their lead in the 19th minute.
Iñaki Peña had to be alert to make some good saves in the first half as Barça got in at the break with a two-goal advantage.
Barça also took advantage of the game to hand a debut to Mexico international Julian Araujo, while youngsters Pau Prim, Dani Rodriguez, Marc Giui, Hector Fort and Unai Hernandez also featured.
Xavi Hernandez made a string of changes in the second half and Raphinha and Ferran Torres both missed chances to extend Barça's lead.
Kobe also had openings to get back into the game but were unable to beat Peña or his replacement, Arnau Tenas, as Iniesta bid farewell with defeat against his former side.
