Iyama Yuta won by resignation, thus successfully defend Tengen crown. Next match against Ichiriki Ryo is January 18-19, the first game out of seven games of Kisei crown. This will be the first time Ichiriki Ryo compete in a two days match as Kisei title match has 7 hours 50 minutes main time per side and 10 periods of 1 minute byoyomi.

Iyama's play suggests to me move 82 (e2) was a crucial mistake. It's locally sente to kill the group but before living Iyama cut and start fighting on the outside and didn't come back to live until move 119. Was it better for Ichiriki to spend a move on the outside (simplest would be m6 connection, is it too slow, try something else like o6 or m10?) because I doubt Iyama would then play a reverse sente move in the e2 area giving Ichiriki another move on the outside (plenty to choose from: right side, top left, centre etc) so then Ichiriki could get his sente there anyway later without all that cut mess on the outside. (and in fact e2 sente was not even a good idea in the game with the change in eyespace of the white bottom left group after the top left fighting!).

The latest Go World has some interesting stats in celebration of Iyama's second heptadiadem - such as having a much stronger likelihood of winning the early games in title match series (overall he scores 70% but in Games 1 and 2 he scores 77%, and in 5-game matches he scores 88% in Game 1. But in Game 4 overall (which by conventional wisdom among pros is the important game in a 7-game title match, he scores just 60%.
But the most important stat, I think, which has been surprisingly overlooked, is that Iyama is well set to break Cho's record of total titles (74). Iyama is on 46 with age on his side (he's 28). He's in 6th place overall but with two more wins he'll move up to 4th, and there's no-one else in the field likely to catch him. He's automatically in the next title match for each of the major events, of course.

More immediate is that if Iyama wins this current Tengen then he breaks Rin Kaiho's 1993 record of 5 wins. That'll be his first "most wins in X big title" record.

What is your source of number of titles?

Iyama has won the 43rd Tengen, achieving six wins and breaking Rin Kaiho's record which has stood since 1993. I wonder how long Iyama's record will stand for? (excepting him breaking it himself).

John Power wrote a very good scoop on closing Iyama Yuta year end. In this article, he said Iyama Yuta has 48 titles.
I recommend everyone to read here
http://www.usgo.org/news/2017/11/the-power-report-2/ but most people might already read it
Iyama Yuta received 1.5 million US dollar just from winning 7 crown + NHK cup alone. Combining with other source of income (book royalties, ads, etc.) I won't be surprised if he gets more than $2 million. He's not just big fish in a small pond, he's rich fish in a golden pond.
Excluding training games with bot, he wins 43 out of 58 games (74%)

48 Titles is the way the Nihon Kiin counts them. See the "タイトル数 48" just to right of his picture on
http://www.nihonkiin.or.jp/player/htm/ki000385.html. What is and is not included on each list is left as an exercise for the reader.

The figure I quoted was from Go World. That was a little out of date of course because that appeared before the latest couple of title matches. But in general the Nihon Ki-in tends to give figures only for what it counts as official and fully open and not-age-or-sex-restricted events. For example, that excludes e.g. Iyama's Super Meijin title because that was an invitational limited to three players, and it excludes playoffs between e.g. the Tengen in each country.
But even that's inconsistent because some events have changed over time. E.g. the NHK Cup is now open but it used to be an invitational event. It's also inconsistent, in my view, in that the Oteai is excluded, even though that used to be the only tournament in town (and also in that the Saikoi, an Oteai spin-off, is included). The Pro Best Ten was essentially invitational but open in that voters could vote for any player. Then how do we classify the Nihon Championship - a major event but open only to NK players? They count it. And they do include the age-restricted Shinjin-O. They count the NK Central Branch Saikoi (limited to Nagoya-based players - and they also include the NK Nagoya-based Okan) but do not count the much tougher Kansai Ki-in First Place. The NK is inconsistent in other ways, too - surprise, surprise.
As a guide, taking Sakata as an example because he is dead but spans the main countable era: he has 64 titles by the Nihon Ki-in count. These are: Honinbo x 7, Oza x 7, Judan x 5, NHK x 11, NEC x 1, Old Meijin x 2, Saikoi x 3, Saikyoi x 2, Pro Best Ten x 3, NK First Place x 4, NK Championship x 12, Igo Championship x 1, Hayago Championship x 1, Hayago Meijin x 1, Highest Dans x 1, Japan Series x 1, JAL Cup x 2.
Some of those were invitational (e.g. early NHK), restricted to high dans or to NK players, etc. And specially for Kirby, Hayago in those days meant 4 hours each (Hayago Meijin) or 3 hours each (some early NHK). Sakata's list above excludes the East Japan Hayago (limited to NK) and his several wins in the Oteai. I, more inclusively, count him as 71 and Cho Chikun at 81, but I'm inconsistent, too

Iyama Yuta (alongside with the strongest Shogi player ever, Yoshiharu Habu) is now being considered by Japan Prime Minister if he can get national honorary award or not.
"I am just astonished and humbled by the undeserved honor," he said.

Iyama is playing Lian Xiao of China today, but what event? Maybe Meijin vs Mingren match? Nongshim cup against Dang Yifei is in February.
