After 21 minutes of drudgery, the match sprung to life courtesy of a penalty awarded to Croatia.
Miyamoto's clumsy challenge on Prso virtually ensured the Japan defender will not be named in the end-of-tournament XI.
Srna stepped up to take the spot-kick, but his near-perfect effort was spectacularly saved by Kawaguchi low down to his left.
Croatia did not seem too disheartened after wasting their golden opportunity, with Kranjcar and Klasnic causing serious problems for the Japanese defence.
Both came close twice, Kranjcar heading into the side-netting and seeing his 30-yarder rebound off the crossbar, while Klasnic scuffed a shot from three yards and had a stinging 20-yard effort saved by the alert Kawaguchi.
Kawaguchi made a superb save down to his left
Japan were restricted to one clear chance, albeit from distance, with Stipe Pletikosa called on to parry Hidetoshi Nakata's piledriver.
Zico's Japan needed to step up a gear after the break and the introduction of Junichi Inamoto and the industry of Nakata seemed to give his side a lift.
Soon after the restart Yanagisawa missed arguably Japan's best chance, when he mis-hit Akira Kaji's pacy ball from the right.
Nakata stung Pletikosa's palms again from distance and late in the game Alex and then Masashi Oguro failed to connect when the ball flashed across Pletikosa's goal.

TRIVIA
This goalless draw ended Japan's streak of 17 competitive matches in which they scored at least one goal. Japan have not won in their last three World Cup matches (losing 0-1 to Turkey in 2002, and 1-3 to Australia in this tournament before the clash with Croatia).
Croatia are now winless in five international matches. Their most recent victory was 1-4 against Austria on 23 May 2006. Croatia have not scored in their last three World Cup matches (losing 0-1 to Ecuador in 2002 and 0-1 to Brazil in this tournament before the stalemate with Japan).
Japan's starting line-up for this game had an average age of 28 years and 210 days, the oldest Japanese line-up in World Cup history. Goalkeeper Yoshikatsu Kawaguchi earned his 91st cap and is now joint second most capped player for Japan, behind Masami Ihara (123 caps). Dario Simic made his 82nd international appearance, thereby becoming Croatia's most capped player of all-time, surpassing Robert Jarni.
50px Japan and Croatia drew 0-0 in the heat of Nuremburg, Sunday.

Both teams worked hard and had clear chances to score but lacked the necessary ruthlessness in front of goal. On a hot field and under the blue sky in the Frankenstadion the conditions won as the match petered out at a walking pace.

 Frankenstadion, Nuremberg.

In the first period Japan's goal keeper Yoshikatsu Kawaguchi kept Japan in the game. Kawaguchi dived low to his left to save Darijo Srna's driven penalty after Dado Prso had been knocked down from behind by Tsuneyasu Miyamoto.

The yellow card for the central defender and captain of the Japan team meant he would miss Japan's next match against Brazil.

The Japanese keeper was centre of the action again when the Croatian coach's son Niko Kranjcar turned brilliantly and rattled the crossbar from 25 yards.

With half an hour gone Kawaguchi got a shock - a bouncing back pass bobbled one meter in front of him. Fortunately for Japan though it evaded his control the ball trickled just wide of the post.

Croatia had the better opportunities. Overall, their physical presence meant they were dangerous from their 11 corner kicks and were capable of making space to shoot from the edge of the area.

If Zlatko Kranjcar might have wished for more luck in front of goal, Japan coach Zico might also rue the lack of finishing from his team. Atsushi Yanagisawa missed an open goal on 50 minutes.

Both sides gave their best in the heat and deserved their first Fifa World Cup point. The result did not play either team out of the World Cup but the advantage in Group F remained with Brazil and Australia who had three points after the first games.
