The training camp has been an exceptional one for the youngster, who is tipped to be a sensation by those in Japan.
As part of the training Maruta was recently sparring with Olympic champion Felix Diaz (17-0, 8), and by all accounts held his own with the 2008 Olympic god medal winner, despite a hug gulf in experience and weight.
Although the training camp comes to an end in a few days it's fair to say that Maruta has learned so much from spending a month stateside in conditions very different from those at the Morioka gym. Sparring with Diaz will have been a huge learning experience and really will have taught the youngster so much more than many fighters learn from actually fighting.
Although we know when Maruta will be debuting, and we also know that the debut will be in Osaka, we don't yet know who he will be facing. The talk however is that the youngster will be facing a world ranked fighter at either 118lbs or 122lbs with an announcement to be in the next weeks.
