The Japanese have played a major part in the taming of the English. They spent months watching endless re-runs of English hooligans abroad, expecting the same here. Instead they see fans coming to have fun and have simply joined in.
My picture will appear in many family albums here because Japanese fans wanted their photo taken with me simply because of my England shirt.
One England fan was even given free drinks all night after convincing gullible locals that he was David Beckham's cousin.
Beckham can take credit for the popularity of the English. They simply adore him and visiting a local school to kiss a few kids has helped his image no end.
On the pitch, you can literally see his popularity, thousands of flashbulbs go off every time he touches the ball.
When you go to an England game and nearly all the locals wear England shirts - admittedly fake - you behave in their country. If people start to wave and cheer wildly when they see you in an England shirt you simply have to cheer back. When everyone else at the game is sober you can't get too drunk and when all the locals put their rubbish in plastic bags you do too.
After the Denmark game in Niigata, most England supporters had to get the bullet train back to Tokyo because there were so few hotels in the town. Everyone on the train received a free goodie bag containing food and drink and the entire station staff lined the platform to cheer and clap the fans.
They even unfurled a banner saying "Thank you. Please come back to Niigata". Normally it's goodbye and good riddance England.
England fans have reciprocated the support they received, joining in the newly-learned chants of "Living Inamoto wonderland". They were genuinely upset when Japan got knocked out.
The Japanese have also been supporting Brazil, but my guess is that most fans will back us on Friday. There are, in fact, very few Brazilians here, even though the TV pictures and level of chanting suggest otherwise.
England won't lose the match through lack of support. The 15,000 England fans here have been magnificent and, for once, they deserve to go all the way to the Final, perhaps even more than the team.
Brazil get extra help
I'm told they had packed their bags for a quick getaway after the Denmark game and, unlike the Irish, were not planning to go for a night on the town with the fans.
Anyway, bring on Brazil. A poor Belgium side gave them a good game and who knows what would have happened if the referee hadn't disallowed a perfectly good Belgium goal?
Indeed, I am more worried about the referee than Brazil, who seem to have the officials on their side.
Brazil were awarded a penalty that should not have been given against Turkey, who then had a player sent off because of Rivaldo's cheating. It's a pity Pierluigi Collina will not be in charge.
Fans on the bawl
At least half the fans are young women who scream every time Japan look like scoring.
They also do the same during the replays at halftime. This created a few problems for Victoria Derbyshire, who is here with BBC Five Live broadcasting from bars.
She could hardly make herself heard above the screeching. At least all I had to contend with when I was on air was the baseball which I'm afraid is still more popular than football here, especially now Japan have been knocked out.
Wenger a turn off
He surely doesn't need the money, yet every night he goes on to make a fool of himself.
It's nothing he actually says, it's just that he's surrounded by idiots.
Possibly with his Japanese a bit rusty, he has a producer talking in his ear throughout the programme and ends up looking like a ventriloquist's dummy.
