Depends on how and where he's played, surely?
Prior to joining Hertha: "Genki Haraguchi made 162 appearances in the Japanese top-flight scoring 33 goals and providing 22 assists"
This very season: "Haraguchi has netted only once for his Bundesliga side so far this season, but in November he became the first Japan player to score in four consecutive final-round qualifiers in a 2-1 win at home to Group B leaders Saudi Arabia."

Lots of twitter traffic about it: https://twitter.com/search?q=Genki%20Haraguchi&src=typd
Would be a good signing to ensure we become a popular destination for Japanese football tourists. Sign him up I say.
