Japan held to goalless draw
Venezuela had the first chance of the match when 17-year-old debutant forward Fernando Aristiguieta missed a header from close range in the ninth minute following midfielder Giacomo Di Giorgi's long-off effort.
But it appeared to be the best chance for either side in a game bereft of clear scoring opportunities.
Mitsuo Ogasawara, playing for Japan for the first time since the 2006 World Cup, fired a sizzling shot from outside the area, forcing goalkeeper Leonardo Morales to save in the 16th minute.
Ogasawara and Brazilian-born Marcus Tulio Tanaka missed a couple more shots, while Aristiguieta failed to catch up with Caracas defender Hose Manuel Rey's free kick to end a goalless first half.
Venezuela piled on the pressure in the second half but managed just one shot on goal through defender Giovanny Romero.
Sota Hirayama, who scored a hat-trick in an Asian Cup qualifier against Yemen last month, was sent on with Sanfrecce Hiroshima striker Hisato Sato in a fruitless attempt to lend the Japanese some rhythm.
"Mitsuo struggled in the first half as the combination with the others was not so good but he did very well in the second half.
"We have three more games this month (in the East Asian championship). We are going to level up our team through the championship, looking forward to the World Cup," Okada added.
Japan will play China, South Korea and Hong Kong in the championship starting in Tokyo on Saturday.
