Indonesia Influence

There are tons of references related to Indonesian culture in the Nichijou series.

Sepak Takraw
In one episode Mio wakes up late because her alarm clock is not working. Looking for her mother, she finds a note by her mother telling her that she's out playing sepak takraw. What flashes in Mio's mind reveals her understanding about the sport. However, that might be the only thing she knows because she doesn't even respond to Yukko's morning greeting which is in Indonesian. Reference to sepak takraw had been decided since Nichijou Prototype.

Indonesian
Bahasa Indonesia is a language used by Indonesians.

Selamat Pagi
Selamat Pagi (スラマッパギ Suramappagi), meaning Good Morning in Indonesian. This is Yukko's morning greeting. Yuuko's greeting is always blurry to Mio and Mai.

Selamat Malam
Selamat Malam (スラマッマラム Suramammaramu), meaning Good Night In Indonesian. Mai's response to Yukko's morning greeting.

Selamat Tinggal
In Indonesian, this means Goodbye. In Episode 7, Yukko, Mio, and Mai run towards a train that is about to depart. Yukko is the only one 'safe' while the other two look on from the other side of train door. Yukko says selamat tinggal (セラマーティンガ"ル" Seramattinga"ru") with the last consonant l pronounced as ru (ル). This fact reveals that Yukko is not that proficient in Indonesian.

Bear as Beruang (disputed)
There is a speculation about a(n) Indonesian pun in Episode 2, Part 5. So far, there has been no confirmation whether the pun was intentional and someone somehow saw it as a straight Japanese pun."Note from GangBunTu:" Am I the only one here that gets the pun as japanese pun instead of Indonesian pun? "aru toki ha kuma, soshite mata aru toki ha~a- ku- ma" which as a pun it could mean "sometimes i'm a bear, other times i'm a devil" which is shown as she takes mio's money I dunno, even if the show did involves parts of Indonesian as their randomness I still think this is a Japanese show aired in Japan. I think you're overthinking this since I doubt they make this as pun that only Indonesian people understand.

While pocketing Mio's money, her elder sister said this phrase :
 * Japanese : ある時はクマ 、そしてまたある時は…ク-マ 
 * Romaji : aru toki wa kuma, soshite mata aru toki wa- ku-ma


 * English translation : Sometimes I'm a bear, and other times I'm a be-ar.
 * Indonesian translation : Kadang-kadang aku ialah beruang, dan kadang-kadang aku ialah ber - uang.

In Indonesian, bear is beruang, while (noting ク-マ = ku-ma → be-ar) it became Ber - Uang (Uang, pronounced similarly to "wang" which means "money"), which sounds oddly similar to "berwang", meaning "to have money". . Putting these together, we'll have: "sometimes I'm a bear, other times I also have money". Yoshino uttered the 2nd phrase at the time when she was pocketing Mio's money. So, was the pun intentional or just a weird coincidence?

Gamelan
This Easter Egg was brought to light by user mikoo at animesuki forum. It appears in several forms throughout the series, like in episode 7 below: To be more precise, since there are lots of tribes in Indonesia, gamelan is a traditional musical instrument of Javanese and Balinese tribes. .

Soeharto
In the "Chic Things" segment in Episode 10, there is a man eating sushi with his bare hands who resembles Indonesia's second President, Soeharto.
