Race science (racist?) sentences in Bunpro-created vocab deck

Hi all,

I’m using the Bunpro JLPT N2 vocab deck to prep for the JLPT in December(!) and I got an…odd example sentence for the target word 濃い. I’m a new user and can’t add attachments but I took screenshots so I have the text verbatim as it has now been taken down:

ヒスパニック系の人たちは目鼻立ちが濃い。
“Hispanic people have strong facial features.”

I thought this was, at best, a weird over-generalization of the very diverse group that is Hispanic/Latino people, and I don’t think this kind of sentiment is pertinent to the study of Japanese as a foreign language. I reported it to the Bunpro team and they agreed with my rationale, took down the sentence, and replaced it with a new one (わたしは父に似て顔が濃いが、弟は母に似て顔が薄い)

Then yesterday I came upon the following sentence for the term 民族 (ethnic group):
民族は同族意識で結ばれているものですから、部外者に入り込む余地はありません。
“Ethnic groups are bound by a sense of kinship, so there is no room for outsiders to intrude.”

This gave me pause. I think this is quite a polarizing statement for a language-learning app. So I looked at some of the other example sentences for 民族 and found the following:

この民族とあの民族は、骨格や肌や目の色といった身体的特徴が全く異なる。
“This ethnic group and that ethnic group have completely different physical characteristics such as skeletal structure, skin, and eye color.”

“Completely different” skeletal structure variations between ethnic groups…I’m sure that doesn’t lead down a particularly sinister line of thought.

So now I start looking in earnest. Here are example sentences for the words 朝鮮 (Korea), 白人 (white person), and 人種 (race), respectively:

朝鮮に住んでいる朝鮮族はモンゴロイドに属しており、首が比較的細くて姿勢が正しく、また、脳が重い方であると言われています。
“Ethnic Koreans living in Korea are classified as part of the Mongoloid race and are said to have relatively slender necks, good posture, and heavier brains.”

インド人などはコーカソイドであるものの、皮膚の色は明色より濃いために白人とは呼ばれないとか。
“Though people from India are considered Caucasoid, they are not referred to as white because their skin color is darker than light shades.”

皮膚の色で人種を分けると大きく白人種・黄色人種・黒人種の三つに分けられます。
“When categorizing races based on skin color, they can be broadly divided into three groups: white, yellow, and black races.”

To put it bluntly, I think it is problematic for a language-learning app to sentences that are derived from and reflect the sentiments of debunked, pseudoscientific, and bigoted theories about race from the 1700s (although Carleton Coon tried to keep it going through the 1930s), and call it a study tool. I don’t think that the Bunpro team endorses this line of thinking, but I don’t know how to respond to the idea that this company is posted this kind of content uncritically and sharing it with users, when (on the other hand) words such as 精薄 include a context flag for being pejorative. And I don’t know if I can in good conscious continue to give my money to an app that keeps this type of sentences up once the issue has been raised.

To get on a slightly taller soapbox, I think this is concerning from an app of any variety, but in a broader scope, I think it is especially troubling from an app that teaches Japanese as a second language when xenophobia, ethno-nationalism, and negative attitudes towards foreigners (sorry, I mean ‘we the intruding 部外者’) are on the rise in Japan (and globally, of course). The recent immigration changes to Japan are not an isolated phenomenon; neither do these sentences exist in isolation. Maybe I am woker-than-thou by bringing this up on the forum of an app, but I don’t think this can be hand-waved away as “it’s just a sample sentence!” because it is clearly not just one sample sentence, and even if it were, the Bunpro team has acknowledged that there is content on the site that does not meet their internal standards; it seems clear that this is a content moderation issue for the platform rather than a few bad apples I found in <10 minutes of looking.

To put it another way: WaniKani has example sentences for 濃い, 民族, 白人, 人種 and none of them include the term Mongoloid.

Wow, I never noticed this. I feel a bit embarrassed to say that if an example sentence like that came up for me, I probably would have just dismissed it as a bit weird and moved on. Thank you for challenging it and bringing this issue to everyone’s attention! We must not fall victim to complacency.

(To be clear, I doubt sentences are chosen on the basis of whether they are agreed with or not, and it can be good to read example sentences even of things you dont agree with, but I do think terms like “mongoloid” dont have a defensible reason to be here)

Yes, I noticed something similar as well. I think there was a definition of “Asian people” (or something similar? I forgot) where the Bunpro summary contained something very stereotypical if not downright racist. I reported it and I think it got taken down. There was another example sentence which I reported and I don’t remember the status of that one. But I have definitely seen some problematic example sentences or summaries in this app.

I feel that some of the sentences are sexist as well. If you’re a guy you probably wouldn’t notice or think twice, but from a female perspective I there are some questionable example sentences, or sentences that reinforce a particular stereotype about women, or many more sentences with a male subject than a female one, things like that. Wondering if other female users have noticed it.

I did notice today (under 男子)
一般的に、男子の方が女子より体力がある傾向にある。

Generally, boys tend to have more physical strength than girls.

but afaik thats true so I kinda let it go

on the other hand for the same word theres an example sentence
男子の中にも女子と同じでお菓子作りや生花、楽器の演奏が趣味な人がいるのは当然だ。

It is natural for there to be boys who have hobbies such as making sweets, flower arranging, or playing musical instruments, just like girls.

I think if you feel something is sexist it’s probably best to report it but I can’t say I’ve super noticed it

First of all, thank you for taking the time to make a post about this. I’m genuinely sorry that sentences like this made it onto Bunpro in the first place.

We have over 100,000 example sentences on Bunpro, written by native Japanese speakers, and unfortunately things do sometimes slip through the cracks. To put the scale of things into perspective, even if 99.9% of our sentences were completely fine, that remaining 0.1% would still mean over 100 sentences that fall short of the standards we want to uphold.

That’s not meant as an excuse, though. If anything, it’s a reminder of how important it is that we continue reviewing and improving our content, regardless of whether something was overlooked, misunderstood, or simply the result of poor judgment at the time.

I can say with confidence that these sentences, and sentences like them, are never included with the intention of promoting harmful ideologies, but that doesn’t change the fact that they shouldn’t have made it through our review process or that they should have been flagged and changed before they impacted your learning experience.

We care a lot about making it a welcoming and trustworthy place to learn Japanese, and we’ll be getting the examples you’ve pointed out changed, as well as taking a broader look through our existing content to identify other examples we may have missed.

Thank you again for bringing this to our attention!

out of curiosity, where do you source your example sentences? just from a database?

All of the sentences are created specifically for use as example sentences. None were sourced from existing databases/sites.

Over the years we have had a variety of people making sentences, a portion were created by individuals doing freelance writing for us while others were written by past and present native Japanese speakers on the team.

thanks for answering my question!

Baader–Meinhof phenomenon applied to racism in language learning should be an interesting thesis?

Oh yeah for sure!
There’s a sentence for 炊事 that has been annoying me (昔は狩りが男の人の仕事で炊事が女の人が仕事だった。| In the past, hunting was the job of men and cooking was the job of women. ← maybe true in some circumstances but why is this broad generalization relevant here? I’m not a caveman. Grog no take JLPT).
I wanted to stay focused on one topic but there’s been a number of sentences I’ve seen that are pro-death penalty, endorse traditional gender roles, and are kinda to moderately narrow-minded in terms of race and ethnicity. I’ve been making a note of them each time and reporting this more egregious ones when I see them. I definitely agree that there are more sentences that fall along the lines you’ve described and I wonder how much of that is implicit bias of the sentence authors slipping in given the number of sentences on Bunpro versus intentionally saying something bigoted. I think these sentences shouldn’t be part of Bunpro (yay Bunpro for removing them) but I don’t think it’s fair to put the onus on rooting out these crappy sentences on female users (or anyone else who’s like hey maybe we don’t need to reinforce racist ideology or the 良妻賢母 mindset in 2026).

I’d read it. But as I said in my post, after seeing two sentences within a week that gave me a ‘hm that’s weird’ feeling, I went looking for more sentences. The ones I pointed out as examples were deliberately sought, rather than served by an algorithm. Still would be interesting tho

God have mercy… It is actually crazy to notice this kind of shit but it is even more crazy to get triggered by this stuff and write an entire master thesis because there are random EXAMPLE sentences on a language learning app that might hurt your feelings.

I really miss the times when people where not trying to be the second coming of Mao´s culture revolution police and search everything for possible insults or whatever just to get the white knight feedback kick.

And btw: A good language learning app should include all (ALL) kind of sentences from the most gentle to the most insulting/rude ones. You ask why? Because they are used if you like it or not. And I for my part at least would like to understand them too…

Is it though…?

I feel like OP raised a pretty reasonable and well-thought out issue

I do agree example sentences should come from many perspectives but maybe debunked race science stuff doesn’t need to be one of them :thinking:
