While brides-to-be may complain that their future spouses do nothing to help them prepare for the big day, it's often the case that men just don't have a clue about what to do to help.

Tokyo-based publisher Can-Z Co. is attempting to remedy the situation by launching a Japanese version of a British wedding magazine exclusively for men called Stag & Groom.

"Women usually take the initiative in planning their wedding ceremonies and parties, but we noticed that some men are also interested," said Kumi Iekura, editor in chief of the magazine, which debuted earlier this month. "They just don't know where to start due to lack of information for grooms-to-be."
