Maika Hamano has signed a contract extension with Chelsea running until 2029.
The 21-year-old Japan forward joined Chelsea in January 2023 from INAC Kobe Leonessa and was briefly loaned to Swedish side Hammarby.
Hamano has since gone on to make 39 appearances and score nine goals in all competitions during her time in west London.
She featured 30 times for Chelsea in all competitions last season and scored six times as the team clinched a domestic treble.
Speaking about her new deal, Hamano said: "Being able to work alongside amazing players and staff, and to give our all toward the same goal throughout a long season -- that's incredible.
