Yuya Osako's 73-minute header handed Japan a perfect start to the 2018 World Cup over 10-man Colombia.
Carlos Sanchez was handed the first red card of this summer's tournament - and the second quickest in World Cup history - after deliberately handling a goal-bound shot in the third minute of the game. Shinji Kagawa slotted home the resulting penalty to put Japan ahead.
Juan Quintero's clever rolling free kick from just outside the penalty area sneaked inside the post, just past the outstretched hand of diving Japan goalkeeper Eiji Kawashima, to level things up before the break.
But Japan would make their man advantage count when Osako jumped highest to guide Keisuke Honda's corner home.
Poland and Senegal, also in Group H and the final two teams not yet so start their World Cup, kick off at 4pm.
55 mins Colombia 1 Japan 1
Colombia need to come up a gear, and there are signs that they are doing so, Falcao is putting it about.
But, not for the first time, Davinson Sanchez is a little bit out of position and, not for the first time, Inui is free and clear down that left flank. He gathers, checks inside and tries to bend it into the corner. Ospina palms it away.
Half time: Colombia 1 Japan 1
Well done Colombia, what an effort. Anybody's game. Awful start for the South Americans, Carlos Sanchez having a complete shocker and sticking his hand out. Also to blame: Davinson Sanchez, who let himself be bamboozled by a simple long ball, and then bullied by the Japanese runner, leading to the shot from which Carlos stuck his mitt out.
But Colombia did not let their heads drop. Cuadrado led several attacks but was, curiously, subbed off. Falcao has produced a captain's innings up front, wonderful movement and classy presence. Falcao eventually won a free in a handy position, and Qunitero cheekily slotted it under the wall.
GOAL! Quintero has slipped it under the wall! Colombia 1 Japan 1
That's a cheeky bit of genius! Love it, well done Quintero. He waited for the wall to jump and threaded it into the corner of the goal. The Japan keeper desperately tried to claw it out.
Some players are protesting, not sure why, not only is it a) obviously in b) they have goalline tech so no point in grousing to the human ref anyway.
37 mins Colombia 0 Japan 1
Falcao goes down. And now Falcao goes down again. Mahoto Hasebe was his assailant both times.
He's doing everything he can to win a penalty, is Falcao. No foul for the first one. Second one, he gets instead a freekick on the edge of the box.
Colombia have a freekick on the edge of the box... it's Quintero...
30 mins Colombia 0 Japan 1
Oooh, shocking play from Colombia. They try to play it back to Davinson Sanchez, hospital pass... the Japanese left-sided forward Yuya Osako steals in and slashes a shot across goal. Should have done better.
Cuadrado has been subbed. Remarkable. Wilmar Barrios, a defensive midfielder, comes on. Tactical move.
20 mins Colombia 0 Japan 1
Colombia committing loads forward, they've got five or six in a line here, but the problem is the obvious one: when they lose it, they are looking very short staffed. Hasebe and Inui have both attempted to lead breaks. Davinson Sanchez is doing some good robust spoiling work.
Drama! Penalty!
Japan break away, just a simple long punt down the middle but Davison Sanchez has made a meal of clearing it. Yuya Osaka races on to the ball and shoots, David Ospina does well but Shinji Kagawa pounces on the rebound. He shoots from the edge of the box, Carlos Sanchez sticks his arm out.
Colombia are all over the shop here. A shot... Carlos Sanchez sticks his arm out and gets in the way. Red card! Penalty!
1 mins Colombia 0 Japan 0
Colombia it is who are stroking the ball around at the back, sensibly favouring the bit of the pitch that is sunny.

Anthems
Colombia's is a smasher! Plenty of Colombians in the crowd and they are giving it everything. It sounds like someone throwing a dinner service down a metal fire escape. Falcao has a T in the E, bless him. Emotional scenes.
The Japanese one could hardly be more different: stately, lilting, dignified.

Earthquake in Japan gives World Cup squad unwelcome scare
Word of a deadly earthquake in Japan and an early-morning false alarm at a team hotel have given the country's World Cup squad some unsettling moments.
Japan coach Akira Nishino, who built his professional reputation coaching Gamba Osaka, said he and a number of his players have acquaintances or loved ones affected by Monday's quake, making for an unwelcome distraction on the eve of the team's Group H opener against Colombia in Saransk.
"The psychological impact is something I'm slightly worried about at this point," Nishino said before Monday afternoon's training session. "As staff members, we are consulting with them and I'd like them to be settled down as soon as possible."
Osaka is Japan's second-largest city. The 6.1 magnitude earthquake killed at least three people - including a 9-year-old girl - and injured hundreds.
Midfielder and captain Hasebe Makoto said that on behalf of the team, he "would like to extend heartfelt condolences to those who've been affected and I hope damage can be limited as much as possible and recovery is as fast as possible."
Makoto agreed that players with loved ones in the Osaka area "might have been negatively impacted" emotionally.
"The team as a whole would like to extend support, and I, as captain, would like to do that," he said.
Japan players with Osaka ties include goalkeeper Masaaki Higashigushi and midfielder Hotaru Yamaguchi, who play professionally in Osaka, while attacking midfielder Keisuke Honda was born in the area.
Nishino said he and players found out about the earthquake shortly after it happened because an alarm went off at the team hotel in Saransk and blared for about 15 minutes around the same time as the earthquake struck.
"The alarm continued for a while and there are some delicate, nervous players, and some of them looked a bit tired in the morning," Nishino said. "So I assume there was some negative impact."
Team officials said that none of the players have reported earthquake-related injuries among family or close friends, and players haven't reported any difficulty contacting loved ones.
