Big Brother - What does Onii-chan mean?
Onii-chan is nothing more than an informal way of saying big brother in Japanese. The character Onii [お兄] literally means older brother. already the chan it is an honorific of childish, informal and intimate treatment, as if it were a diminutive (little brother).
The most formal and common is to use the suffix san, so we also hear the words onii-san for older brother. You can use these expressions after the person's name as an honorific (Kevin-oniichan).
This address is used for any older sibling you have, sometimes it is even used with people you consider a sibling, even if they are not related.

Oniichan or Onii-chan, which one is right?
There is no correct way, this dash is just a romanization option that we use to separate the words brother from the suffix chan or another suffix like san. Be careful not to write just onichan because then you will be referring to the demon, ogre or monster Oni [鬼].
Big Sister - What does Onee-chan mean?
Onee-san is the informal way of saying big sister in Japanese. The character "Onee" [お姉] literally means older sister. As we've already mentioned, the suffix "chan" is an informal diminutive (little sister).
Onee-san is the more formal way of saying big sister. Because women are highly respected, men generally tend to use onee-san more than onee-chan depending on the family situation.
What does Anne mean?
"Ane" [姉] is another way of referring to an older sister, especially when talking about your own sister to others. Another even more formal and archaic way is "aneue" [姉上].

Imouto and Otouto - Younger sister and brother
To refer to the younger brothers, we use the word otouto [弟]. The younger sisters are called imouto [妹].
These words don't usually use suffix, except when referring to members of another family, like your friend's younger sister, you should use imouto-san.
Unlike the terms onii-san and onee-san, you don't use "imouto" and "otouto" as often to talk to your younger siblings. Japanese people usually call younger people by name.
If you search for “younger sister” in the Japanese dictionary, you will see that there are endless ways to convey the idea of a younger but unusual sister.
Do you happen to like younger sisters? I hope you're no lolicon if I don't kill you! The little sisters are all mine!

Futago - When are twins?
If both are twins, what do they call each other? Who will decide to be the younger brother or older brother? The Japanese word for twins is futago [双子] which literally means children in pair or set.
In reality, everyone is already aware that even twins, even when born at the same time, are taken in an order, so those who first came out of the mother’s belly are considered older. So, it can be said:
- futago in the ani [双子の兄] twin brother;
- futago in the ring [双子の姉] twin sister;
- futago on onisan [双子のお兄さん] older twin brother;
- futago on oneesan [双子のお姉さん] older twin sister;
- futago no otouto [双子の弟] younger twin brother;
- futago no imouto [双子の妹] younger twin sister;
- tsuin [ツイン] from English twins;

Kyoudai and Shimai - Other ways to talk about siblings
If we want to speak in the plural, brothers and sisters, we can use the combination of the ideograms of older brother and younger brother. Brothers in Japanese are spelled "kyoudai" [兄弟] and sisters in Japanese are spelled "shimai" [姉妹].
Kyoudai can encompass all siblings, even females, although you can rarely find Kyoudai written in other ways using 2 of the 4 characters used for siblings [兄-弟-姉-妹].
