Talking with People through Twitcasting TV

Want variety in listening to real people speak real Japanese? I introduce to you! If you haven’t heard about it before, it’s a popular live streaming site. The concept is not really new since there are other sites like and but somehow this site caught my attention more when it came to practicing my listening and reading with real Japanese people.

What can you find at

This site is where people can do live video or radio streams. The ‘CASter’ doesn’t see a list of who is watching or listening but there is a counter and people can comment. The site is popular not only for Japanese users but also Spanish, Brazilians some Koreans. English speakers are rare but they’re up there occasionally. You can easily sign up if you already have a Twitter account (and recently the Book of Face). No worries if you don’t have either as you can view without signing up. Commenting is not required although some CASters prefer comments.

The site also has an iphone app so if you really enjoy the site you can carry it with you. When someone is the CASter they get rankings. People can send cute animated gifts and a ‘continue coin’. Each CAS is 30 minutes. If viewers like the CASter they can give continue coins to extend the CAS. If the CASter doesn’t get any then he will have to restart. It’s just a small interruption so it doesn’t matter if you get the coins or not.

How you use it

I use this site mainly for listening. Although I live in Japan and can hear real conversations anywhere, I am also an English teacher who listens to broken English for more than 8 hours a day. Therefore I tune into some random streams at home when I don’t want to listen to the TV. I also use the site for reading. There are lots of viewers who comment and use a lot of colloquial expressions. Depending on the CASter, the comments go by fast so you will improve your reading speed.

I use the plugin Rikaikun (for Chrome browser) to mouse over kanji I can’t read. I sometimes write my own comments but I’m more interested in what the CASter is saying. Although it can be exciting to write something since most CASters read the comments out loud and then reply.

Choosing who to watch/listen to

I love to watch イケメン (ikemen) or good looking guys and listen to pleasing voices. I don’t really like  hearing high-pitched tones so I avoid them. Some girls who do live streams do things that disinterest me (like putting on makeup) so I mainly watch people who just talk to the camera.  You have to discover what kind of material you like best.

Sometimes there are CASters who do all-nighters.  One night I left a CAS on and went to sleep only to wake up and find out at 9am he was still going.  I’m kind of curious what he was able to talk about for 8 hours . . .

Some ways to use this site beyond just listening practice

– While I hardly use this site to write comments, I recommend anyone who wants to practice their writing to do so.

– If you are an Anki lover, you can  copy and paste phrases and words people often use into your deck.

– If you are a Twitter fanatic and use twitter to practice Japanese, this site is perfect in finding real people to follow. I often don’t know who to follow on Twitter because I don’t know if the person is a bot or just plain boring. Twitcasting can help you learn a lot more about the person. Even if you don’t understand what is being said, you can get the vibe of a person by how they sound. I’ve befriended two people from twitcasting and we often tweet each other.

– Start your own stream regardless of your level. Anyone who feels confident enough to try a live Japanese CAS, by all means try!

The benefits

You get to watch and listen to unrehearsed, casual Japanese.  You can learn slang, hear many accents from different areas of Japan, be blasted by kanji and other common words, as well as experience the 絵文字(emoji) trend, which I consider a part of Japanese (internet) language.  Add the comments feature and the ability to create your own stream, and you are practicing all four Japanese skills.

A few useful things to know

– CAS: stream
-“____CAS”: name of stream ex. 寝る[neru]CAS (sleep stream), 乾杯[kanpai]CAS (drinking stream), ect
– 初見[shoken]: literally means; seeing for the first time, first sight. But basically used like はじめまして[hajimemashite]. This words is used frequently「初見です!」

Be prepared to hear broken English if you type in English or if you have your picture as your icon and clearly look non-Japanese.  Since you are here to study Japanese, make sure to steer away from this.

Happy CAS viewing!  Maybe you’ll see me in a future stream? Or maybe I’ll see you?

Talking with People through Twitcasting TV — 15 Comments

  1. Thanks for this; doing something like this for learning Japanese never really even crossed my mind. I’m still a little shy about my output though so the few times I was asked to comment I didn’t really produce anything. =p
    In some of the more active rooms though, it was interesting to see and hear how they interacted with one another. I even got into one where two people were fighting over comments and the person casting the stream thought it was hilarious and was encouraging them, which I found quite entertaining.

    • Yeah, that’s what I like about the site. It can get really funny at times. I try to view the more interesting people that have more than 10 viewers.

      I understand how you feel about commenting. I think it’s the same for me. I rather watch and read the comments.

      Thanks for reading.

  2. Thanks for the post. There are some interesting streams on that site. There are even people streaming content in other languages (e.g. Spanish) so it could be of value to people learning languages other than Japanese.

  3. Have been checking it out for a while. Not only are there people just conversing with the camera, I found a live recording at Disney Sea! 懐かしいな! I imagine with the i-phone, people can twitcast so often. I feel like I’m being brought back to Japan.

    • that’s great! Yeah, I know it can be a bit creepy just watching people talk but they don’t really care it seems. So many people stream random things like playing their card games, or video games, drawing and such. Enjoy ^_^

  4. Argh… Thought I could use this to listen to Japanese while at school (since Japan-A-Radio is portblocked by the college firewall, presumably all audio streaming services are). Sadly, no, I can’t watch CAS here either. At least the Twitcasting FAQ says what port ranges are used for viewing (995, falling back to 8091-8099 if unavailable)… Oh well, I’ll try when I get home.

    • Okay, it works just fine from home :D And seriously, wow, this is cool. In the first two I’ve watched, I found a guy with overly loud dogs constantly interrupting his stream, and someone else with mad guitar skills.

      But honestly, why does my college have to portblock the good stuff? Steam I can understand, they don’t want all their bandwidth being sapped by a 32-player TF2 deathmatch. But Japan-A-Radio and lower-bitrate twitcasts don’t take that much bandwidth, so why block all streaming altogether?

      • That sucks about your school. It’s like when good sites in the states are blocked here in Japan. Dang geoblock. Anyway, enjoy the site. I love it because it helps me pick good twitter users since I know what they sound like and get a gist of their personality. I’m not good enough with my Japanese to just figure it about by reading only.

  5. I know this post is nearly a year old, but does anyone have any recommendations? I mean, a rec. list of Japanese CASters to watch.
