Whilst we haven't had the names of the fighters that Maruta sparred we have been informed that Maruta looked sensational and impressed all those that saw him in the ring. This is despite the fact Maruta is just 17 years old.
A post on the Muto boxing blog seemed to the echo the general feeling that Maruta's debut, later this year, is something to be excited about and it seems clear that those in the know are really tipping the youngster who seems to be regarded as the next in the growing line of Japanese super prospects.
This sparring session comes just a few days after Maruta had been sparring Shun Kubo and it's become abundantly clear that the youngster is developing a lot behind the scene. It's also clear that when he does make his debut he will be experienced in having gone rounds with some very talented fighters ranging from domestic level to world class and that his accumulated experience will help him be fast tracked.
Although it's still too early to know how good he is, the general view of those who have seen the youngster spar is that he's a special talent, much like Naoya Inoue and Kosei Tanaka. If that's accurate then Japan has another sensational talent on their hands.
