Something that bombs, to me, is something that either sells so few copies it doesn't even register on the charts or something that leaves a incredible amount of its shipment unsold. It's highly unlikely the sell through for those titles was any less than 70-85% in its first week. 

A game that had low expectations, high sell through, and modest number doesn't constitute a bomb. There are dozens more that sold far worse, and they had things working for them that these games do not. I think game sales have more to do with advertising, quality, and appeal than country of origin. 

For your specific examples, I'd ask do you think they would have done worse if published by a different company? I do, because of the reasons I listed below. Also considering that company put more advertising behind different projects. Especially with games that are guaranteed to reach a certain threshold.

Sorry, I'm a little lost. Was the question "do Western developed games do well in Japan" like I thought it was, or was it "do these Western developed games do well in Japan" like it suddenly seems to have become?

No, the idea was, that "Western developed games do bad in Japan", if you dissagree, feel free to give me examples, so we can discuss them, find some patterns, dependacies, etc. 

I think they do bad in general, and I've given a few examples of games with relatively high critical acclaim, as I also stated that quality doesn't make much difference, provided also a few exceptions, for games that have done good, nothing amazing if we consider attach rates, but still good, for Western developed games. Feel free to prove me wrong.

As for the first paragraph, it's semantics. There are no legal definitions of bombing or selling poorly, although I like your description. Let me then say, that those games sold poorly, sold little numbers of copies.

In the bolded, lies the problem in my opinion. I am arguing that, when it comes to Japanese gamers, the cultural barriers, specific preferences and close-mindedness play bigger roles those things you have listed. 

As for the last paragraph. No, I don't think it would change much, that's also the point. I think, that publishers could have less effect when it comes to Western developed games in Japan, than they could have elsewhere. I only brought up SE as a publisher, because you argued, that the reason why CoD got relatively big in Japan, is because SE have done a good job publishing it in Japan, localisation, advertising, etc. so I wanted to counter that idea, by providing examples of games published by the same company, so I assume published with more less the same effort, that sold relatively poorly, also games that got high notes from reviews.

outlawauron already provided three off the top of his head. You just brushed him off though. Did you respond to Rol's point about the DKCR specifically (and DKC generally)? I forget. Also, refresh my memory, but who developed the game on this week's list with over 780k in sales (and growing)?

In case I'm being too subtle, I'm wondering if this is an honest question, or if you're going to be one of the folks who makes a statement and then ignores all contrary evidence.

No, it was me who provided those three, as a examples off games that sold good numbers, but not really great when taken into perspective, in comparison.

Those two games are good examples, it seems Nintendo IPs have wide international appeal. 

OK so now I have a question for you, leaving that statement behind, as it was a generalisation and you proved that it's imperfect. Do you say that games of Japanese origin and games from abroad have a equal footing, an equal chance of success in Japan?

Wii U and Vita up again? WTF! Good, at least.

Fair question, and my apology about the tone I used earlier: it seems I misjudged you, partly because I didn't read carefully enough.

To answer your question, I would have to say "no." While Western games have a good chance of performing well (in context) in Japan, the bulk of the successful titles, and nearly all the heaviest hitters, are Japan-developed. To that end, I agree with the premise that Japanese games are much more likely to succeed in Japan than Western games are: I just disagreed with how far the earlier statement went!

I caution though that much of this likely has to do with national tastes. Most of the big Western games that make it to Japan tend to be FPS, sandbox, or third-person shooters. I can't think of any FPS game that's done particularly well there, regardless of developer.

Sandbox games also generally don't do that well, with the notable exception of the (very Japanese-culture focused) Yakuza series. It's noteworthy though that the Yakuza series' Western sales are generally tepid despite the vast success of titles like Saint's Row and GTA, which implies its appeal does lie in large part on cultural appeal, or something else that doesn't seem to translate well. GTA actually sells quite well in Japan though: this site has several entries, including GTA IV, as crossing the 400k mark, something that's remarkably rare for any game in this day and age.

Third-person shooters also aren't big sellers in Japan, with the exception of the newer Resident Evils, and I have to wonder if part of that series' success isn't due in large part to the large fanbase built up by earlier entries. It can't be solely due to the developers, as the Western-developed Operation: Raccoon City was a great success in Japan: arguably, it had the largest market penetration there.

As an aside, there are also Western RPGs. Those don't do incredibly well over there. But then, it's the same country that's also been the most devoted to JRPGs, so I'd argue tastes have the most to do with it.

In short, I'd argue that the data show that the relative 'failure' of Western-developed games likely has more to do with the choice of genres than with national origin. The AAA heavy-hitters from Western studios largely fall in genres that the Japanese tend to not care for as much. That, in my mind, largely explains the difference in results.
