Carles Perez was Barcelona's hero as the La Liga champions were victorious in Spain on Saturday.
The second-half substitute netted in the 59th and 86th minutes as Barca defeated Vissel Kobe 2-0.
The result came after Barca had been beaten 2-1 by Chelsea on Tuesday in Saitama.
Antoine Griezmann, who joined the club earlier in July from Atletico Madrid, played the first 45 minutes but is still yet to get on the scoresheet for his new employers.
There were some familiar faces in the opposition line-up with former Barca players Andres Iniesta, David Villa and Sergi Samper all featuring.
Iniesta had his chances and 28,000 fans sighed their frustration as he put a fierce shot just wide.
"It was my first goal for Barcelona and I'm glad to score even two," Perez said.
"It's been my dream to score goals for this great team since my childhood," he added.
The win wrapped up Barcelona's pre-season friendlies in Japan following their 2-1 loss to Chelsea earlier this week.
