It's now been announced that the OPBF "interim" titles will be retro-actively re-named the OPBF "silver" title, following the naming convention of the WBC and their "silver" world and youth titles.
Last week the JBC declared that they would be reviewing their stance on OPBF "interim" belts, and today they have made their stance public. They will not recognise the titles, at all.
Essentially what the JBC have said is that they will not sanction OPBF "silver" title bouts and will not recognise them. This is because they feel the titles are set to be misused, and aren't used as a title belt for when a champion is inactive but instead used as just another title, much liek the WBA "interim" world titles have been.
It does seem like Japanese fighters will be able to fight in OPBF "silver" title bouts away from Japan, but not in the country. Essentially with the JBC treating them with the same respect they treat the WBA "interim" titles.
