According to Nikkan Sports, it seems Hitoshi Tamura is leaning closer toward exercising his international FA option. If he does, it'll likely be done on the 16th, the last day players have to exercise their options. Tamura has also already informed the Softbank Hawks of the situation and will continue to negotiate with the club until then.
Sponichi also mentions that the Hawks are moving to a contract signing system that gives players a somewhat low base salary full of award bonuses. And the Hawks are apparently sticking to this system with Tamura. Unfortunately, Tamura is looking for a multi-year deal with security so that he can move his family down to Fukuoka.
