Today is Good Flat Chest Day in Japan. Wait… What?

Peter Payne by Peter Payne

in Your Friend in Japan

The month of November is filled with lots of silly “good [whatever] day” special events celebrated by Japanese Internet users. November 8th was Good Oppai Day, and November 7th was Good Tummies Day. Today, November 12, has been declared Good Flat Chest Day, a day to celebrate pettanko girls all across the internet. In this blog post, let’s rank the best anime flat chests!

Great news! To celebrate all the awesome new doujin titles J-List has gotten in stock after the recent C107 Comiket doujinshi event, we’re having a flash doujinshi sale! Through January 14, get 15% off automatically on all shipping-from-Japan doujin titles. Start browsing here!

Today is Good Flat Chest Day, a day to celebrate pettanko girls!

Why Does Japan Have a Day to Celebrate Flat-Chested Girls?

Why has November 12 been designated as Good Flat Chest Day in Japan? It all comes down to phonetics. The word for “good” in Japanese is ii (pronounced like the letter E), so the number 11 has come to stand for “good” because it looks like ii. It’s virtually impossible for non-Japanese to understand these phonetic pronunciations of numbers, and I’ve pretty much given up on it myself.

It is interesting to reflect on why anime flat chests are so popular with fans.

  • Comedic Tension. There are endless opportunities to create humor when a flat-chested girl finds herself in the middle of well-endowed companions.
  • Everyone Loves an Underdog. We naturally root for the A-cup girl to defeat her D-cup rivals in love.
  • The Moe Factor. Flat-chested characters are more likely to trigger feelings of protectiveness from fans.

Who Are the Most Popular Anime Flat-Chested Girls?

Let’s rank the top pettanko girls in anime history!

Taiga Asuka has a flat chest

First, we have to celebrate the queen of tsundere, Taiga Aisaka. The episode where she needed to buy a swimsuit to attend swim class with the other students was so much fun to watch. Poor Taiga!

Louise from Zero no Tsukaima

Louise from Zero no Tsukaima is another fiery girl with small boobs, who is naturally surrounded by well-endowed characters who love to show off their chests to her.

We can’t leave Shana out of this post!

Shana from Shakugan no Shana is another popular tsundere who wouldn’t have the same appeal if she didn’t have a lithe build.

More Pettanko Girls to Celebrate on Good Flat Chest Day!

Megumin is another beloved pettanko girl

Megumin from Konosuba is another character fans love because of her slender figure. The contrast to the more buxom characters in the show drives the comedy perfectly.

I love the tension between Nana Deviluke and her sister

To Love-ru has a lot of fun characters to love, and one of my favorites is Nana Deviluke. She’s flat as an anvil, and extremely jealous of her sister for having bigger boobs than her.

Even More DFC Anime Girls

Another cute girl to celebrate on Good Flat Chest Day: Last Order

When you think of flat-chested anime girls, you might think of Misaka Mikoto from the Toaru Majutsu no Index anime. But her more diminutive clone, Last Order, has even her beat in the DFC department!

Riko-nee and Ako-nee are so competitive when it comes to their boob sizes

Then we have the Suminoe sisters from KissxSis, the most perfect ecchi anime there is. Both girls want to claim their not-related-by-blood younger brother Keita for themselves!

Remember when we all had a crush on Silica from SAO?

Another legendary smol chest girl is Silica from Sword Art Online, because every side character in that show is doomed to have small boobs. Did you have a crush on her back in 2012?

Koneko is my favorite anime flat chest girl

Koneko from High School DxD is another compact heroine we love. The other girls might have bigger chests than her, but she’s got a bigger heart!

Another reason to love Sailor Mercury: her flat chest

Finally, we have the quiet underdog of the Sailor Moon team, Ami Mizuno. Back in the day, fans weren’t obsessing over small boobs, but we all somehow understood that part of Sailor Mercury’s charm came from her modest personality… and her equally modest figure.
