Borussia Dormund started their Asia pre-season tour with a huge win in Japan.
The friendly match was Dortmund's first appearance in Japan since 1997, when they defeated Cruzeiro in the Intercontinental Cup.
The pairing against J.League side Kawasaki Frontale was made through Puma, the kit-makers for both sides.
The friendly was a homecoming of sorts for Mitsuru Maruoka, who is on loan to Dortmund from Cerezo Osaka.
But the night's main attraction was undoubtedly Shinji Kagawa, the Samurai Blue star and one of the J.League's most famous exports.
New Dortmund manager Thomas Tuchel praised the response of Japanese fans, with over 5,000 attending a training session the day before the match.
Shinji Kagawa needed just five minutes to score the game's opening goal with a header from close range.
Half an hour later, the former Manchester United man added a second goal to his tally.
Germany star Marco Reus did not disappoint fans with a fine performance up top.
Kagawa and J.League veteran Yoshito Okubo swapped uniforms at halftime.
Fans of Cerezo Osaka, Mitsuru Maruoka and Shinji Kagawa's previous club, were amongst the fans who came out in droves for the sold-out match.
After Kagawa scored twice, Maruoka landed on the scoreboard by beating Frontale backup Yohei Nishibe in a one-on-one encounter.
Pierre Emerick Aubameyang delighted fans with two goals in the second half.
Frontale were unable to find a goal despite several chances created by Kengo Nakamura and others in the second half.
Dortmund players thanked the crowd with a Japanese banner after their 6-0 win.
Dortmund mascot Emma, who has accompanied the team on their Asian tour, signed autographs before the match.
24,650 attended the match at Todoroki Stadium, which opened its new main stand this season.
Most supporters stayed after the final whistle to greet their favorite players as they took a lap of honor around the track.
Frontale supporters unveiled a "Forza Dortmund" banner in the style of their own "Forza Kawasaki" banner after the match.
