Onigiri (Omusubi) revisited: An easier way to make Japanese rice balls, step by step

[Update:] See all kinds of onigiri on my new bento-only site, Just Bento.
[Another Update:] Check out the Onigiri FAQ for answers to most, if not all, your onigiri related questions!
[One more Update:] A few people are obviously not taking the time to read or follow the links suggested properly. Otherwise they would not keep asking the same question, or worse answering it wrong, over and over. So please let me repeat again:
The best rice to use for standard onigiri is the kind usually sold as Japanese rice or 'sushi rice'. It is NOT THE SAME as 'sticky rice' or 'sweet rice' or 'glutinous rice'. And no you cannot use jasmine rice for successful onigiri, the way onigiri are supposed to be! The right kind of rice, properly cooked, is not the same as the wrong kind of rice, cooked until mushy and pressed together in a gluey fashion. If you can't get a hold of Japanese rice for some reason, there are a few other rices that can be substituted. See Looking At Rice for a complete explanation. That should make things clear! (end Update)
One of the most popular entries on this site is the one about onigiri, or Japanese rice balls, which I wrote back in 2003. (A lot of people landed there searching for onigiri as portrayed in anime or manga, especially Fruits Basket...which is interesting.) It was one of the very early entries on the blog, and I gave the traditional way of making the onigiri: hot rice put on moistened and salted palms, which quickly turn red and sore because of the heat from the rice.
I've made hundreds of onigiri in the 3 years since I wrote that, because onigiri are such great portable meals for picnics, not to mention party food and late-night snacks. But let's face it, those red sore palms aren't too pleasant, and the rice grains do tend to stick all over the place. Also, portioning with the rice scooper can be a bit erratic unless you are an onigiri-making expert.
With ideas from several places including cookbooks, Japanese TV shows and my mother, this much neater method of making onigiri evolved. It requires no special molds or equipment. It ensures that all your onigiri are uniform in size. Your hands never get too hot and red. And, if you're going to bring them on a picnic or store them for eating a bit later, they're already conveniently pre-wrapped in plastic.
A word here from my mom about the most frequently asked question regarding onigiri: alternative fillings if you can't get a hold of, or don't like, the traditional fillings like umeboshi (pickled plums), tarako (salted cod roe), or katsuobushi (bonito flakes) with soy sauce. She says, "Onigiri isn't about the filling really. It's about enjoying the flavor of good rice." She has a point there. Use good rice, prepared properly, and the filling becomes secondary.
So, I present you... Onigiri 2.0 :).
Onigiri 2.0 (Easier, neater onigiri)
There are a lot of steps here, but once you have done a couple this way you will be turning out tons of rice balls in no time.
Equipment and ingredients needed:
- Sturdy plastic wrap that is not so thin that it will get weak when exposed to a little heat, or too thin that you spend more time un-sticking it form itself than using it. Saran Wrap is great, or Glad. (I used a green colored wrap for the sake of photographic clarity, but you can use clear wrap of course.)
- A small bowl or teacup that is the size you want your rice balls to be. I like to use small teacups so that the onigiri don't turn huge. For party-sized mini-onigiri you can use a sake cup or egg cup. The teacup used here holds about 2/3rd cup of liquid.
- A rice scoop or a spoon
- Properly cooked white or brown Japanese rice or "sushi" rice or uruchi-mai, NOT 'STICKY' RICE and definitely NOT JASMINE, LONG GRAIN OR OTHER RICE Please read the Looking At Rice post if you are confused about what kind of rice is best to use for onigiri.
- Salt, preferably in a salt shaker (or you can just sprinkle with your fingers)
- Water
- Fillings of your choice
Covers of your choice such as nori seaweed
Mise en place: Make ready your teacup, a cup or bowl holding some water, salt shaker, rice, rice scoooper, fillings, plate to put the finished onigiri, and plastic wrap roll. It's easiest to do this near the sink, if you have the space.
Line the small bowl or teacup with a piece of plastic wrap that's big enough to hang well over the sides. Press the plastic down into the cup with your fingers.
Sprinkle the inside of the cup with a little water. Shake out the excess into the sink.
Sprinkle the inside of your wetted, plastic-lined cup with salt, turning the cup so the sides get sprinkled too. Shake out any excess salt.
Fill the cup with rice up to the brim. No need to press down; just fill it loosely.
Poke a hole in the middle of the rice, about halfway down in depth, with your finger.
Poke your filling of choice in the hole - about 1/2 a tablespoon or so. Here I have used traditional umeboshi.
Lightly press the rice over the filling.
Gather up the ends of the plastic wrap.
Twist and squeeze, pushing out any excess air. Twist tightly to form a ball. The squeezing is critical for ensuring that the salt sinks into the surface, and for making sure that the rice grains stick together enough so that the ball will not disintegrate when you bite into it.
At this point, if you just want round onigiri you can squeeze and press a bit and you're done! If you want triangular rice balls, you just need to squeeze a little differently.
Form an L shape with one hand and make three corners on the ball...
Use the other hand to turn the ball and squeeze back to front. Squeeze, turn, squeeze. Practice makes perfect!
And, here you have a perfectly shaped triangular onigiri.
If you're going to bring the onigiri on a picnic, just leave it in the plastic wrap, and bring along the nori separately; wrap the onigiri with the crisp nori just as you're going to eat it. If you're going to eat the onigiri right away, you can re-use the piece of plastic wrap for all the onigiri balls you make.
This method works marvelously for brown rice balls as well as white rice balls. Brown rice balls can be a bit tricky, since brown rice is not as sticky as white.
Non-traditional fillings redux
A lot of people ask about alternative fillings for onigiri. Basically anything that goes well with rice, is not too wet or oily, and is highly seasoned (read: quite salty) will work. There are several listed in the original onigiri article as well as in the comments. Remember that any filling you use must be well cooked. Here are some that have been successful for me to varying degrees:
- Anything flavored teriyaki-style: chicken, pork, beef, etc., chopped fine and cooked down a bit if too sauce-y.
- Chopped plain black or green olives. Salt cured ones work better than oil cured.
- Char siu pork, (there is a recipe for a simplified version at the bottom of this page) chopped up small. Don't use a fatty piece of pork though, or the fat will leak out to the surface of the rice ball, which is not only rather gross but will make the grains fall apart.
- Tiny little meat balls, well flavored with flavorings of your choice. Just salt and pepper do fine.
- Well drained pickles. Japanese style pickles may suite best but regular Western style pickles work quite well too.
Remember also that you can have plain onigiri, flavored only with salt, to bring along as the carb component of a portable obento lunch or picnic, to eat with other things like chicken wings, boiled eggs, little meatballs on a stick, or whatever strikes your fancy.
Yaki Onigiri (Grilled onigiri)

The rather burned looking onigiri on the top right in the photo above is a yaki onigiri, or toasted onigiri, made of brown rice (genmai). It's actually 'toasted' in a hot dry non-stick frying pan until the surface rice grains get brown and toasty, then brushed on both sides with soy sauce. This is a great way to revive onigiri that's gone a bit dry on the outside. You can put a little bit of sesame oil in the pan to add even more flavor. Brown rice onigiri is especially good as yaki onigiri, since the toasting really brings out the nutty flavor. You can also toast the onigiri in a toaster oven; toast first, then brush with soy sauce, and toast a bit more until your house smells like a giant rice cracker.
(A word of clarification here: What makes this method a little different is the use of both the cup and the plastic wrap: the cup helps you produce uniformly sized onigiri, which can be an issue for onigiri neophytes, and the plastic helps to avoid the red, sore hands. It's meant to be very beginner friendly. If you or your mother/aunt/wife/friend already uses a similar method, terrific! That's just confirmation that it works, isn't it? And, if you/your mother/etc. can whip out tons of onigiri without resorting to 'gimmicks', all the more power to you. )
Before asking a general question about onigiri, please check out the Onigiri FAQ page. Chances are your answer is already there!
Update, September 2009: I am closing comments here, since the same questions keep getting asked over and over. Maybe there are too many comments for people to read through. Most if not all your onigiri questions are answered in the Onigiri FAQ. If they are still not answered, then ask your question over there. Thanks!






Excellent!
I just used this method to make my first Onigiri (well first successful ones) and it works great! I didn’t have a teacup so I used a 1/2 cup measuring cup and they turned out perfectly.
I like my nori a little soggy though so I stuck it in the bottom of the cup before I put the rice in. Worked like a charm. So quick, so simple.
Thanks! I’ll be making lots more with this technique.
This works!
No more burning my hands! No more different-sized onigiri!
I tried this method and the riceballs turned out great! What a simple and wonderful idea.
Thank you!
So easy that I can't believe I didn't figure it out myself..!
Thanks for this great tip! Every time I got my hands burned and messy while making onigiris. Today I tried this and it totally works! Very big thank you from Finland! :) devours an onigiri with one bite
Omigosh!
I’ve made onigiri PLENTY of times, and I can’t believe I never thought of this! I always wrapped mine after, and half the time they’d fall apart! (So I’d feed them to friends who were hanging around the kitchen!) This sounds so much easier, thank you!
And tuna soaked in soy sauce with kosher salt sprinkled on it is an excellent, cheap filling—especially if you have no access to the “traditional” ones. It’s what I always make, and I find it absolutely delicious!
^_^
Yum, I <3 onigiri; it was the first japanese food that I tried to make (which could explain why it’s now my favorite) for my new bento boxes. The first ones came out reeeeally funny looking and not so tasty, but I got some books, checked a lot of websites, and messed around with fillings/mix-ins. As of right now, the type that gets me the most compliments has sweet scrambled egg bits mixed in to the egg, stuffed with chopped bacon (=breakfast onigiri?). It’s great to pack in your (or someone else’s) bento, though it can get sticky if you don’t wrap them in plastic wrap. ^^; just thought I’d share…
hi
well… my mom keeps on asking me how to make a rice ball and i don’t even know how so i serached it up and i found your site.now my mom stop bugging me thx anyway how do u make okaka flavour rice balls is it spicey?
okaka
Okaka is dried bonito flakes, or katsuobushi, that has just enough soy sauce added to it so that it’s barely moist but not dripping. Nothing else other than the soy sauce is added so it’s not spicy.
Thanks for the help
maki
Thanks for the excellent instructions. I used your method to make onigiri for the first time with my rice-crazy children (aged 4 and 7) and they loved helping to make it and devouring the results. We used little nuggets of some leftover pork/bison pate from the fridge as a savoury filling which worked very well indeed. To make it even more fun, we decorated the balls with little nori stars and sharks cut out using a shaped paper punch, an idea I’d seen in the cookbook that came with my laptop lunch box. We will definitely be making these again!

Lots of Japanese recipes
samira, there are lots of other Japanese recipes on this site - take a look here:
http://www.justhungry.com/recipes/japanese
You may want to start with the ones that are marked “Basics” - or anywhere you want really.
Good luck with your Japanese studies!
Keeping Rice
I need to take some type of food in for school, so i decided i wanted to do something Japanese. This is because i love all things Japanese with a passion. So, anyway, i have to make most of it at school, and i was thinking i could pre make the rice the night before because we have a limited time to cook the food. So i was wondering if there was some way that i could make the rice before hand and bring it in the next day to make onigiris. Can someone please help me? =(
P.S. I also need some good and simple filling suggestions if any body has any.-Please.
onigiri rice
If you cook the rice the night before, take it out of the pan or cooker while still a bit warm and wrap well in plastic wrap, then in a ziplock bag. Then either refrigerate or freeze the rice. (If your school has a microwave on hand freezing may be better.) Before using the rice warm it up in the microwave if possible. If not, try to arm it up in a double boiler (a bowl suspended over a pot of very hot water).
The reason you need to have warm rice is that cold rice will be very hard to stick together.
For fillings there are tons of suggestions in the body and comments of this article, as well as the other onigiri article (listed in the right sidebar)
Made 2 yaki onigiri tonight
Made 2 yaki onigiri tonight with chopped up fake crab legs inside using leftover rice from making 3 maki rolls. One of them fell apart during the last stage (with soy) of toasting. But, the triangular one, which was handled more to get the shape, held up and will be lunch tomorrow. Smeared a bit of wasabi on one side cause I like it spicy. :)
What is the purpose of the
What is the purpose of the seaweed around the rice balls and is it okay to eat? I’ve never had onigiri before and so I was just curious about it.
the purpose of nori (seaweed)
The nori is used as a sort of protective wrapper, it helps to hold the rice together, and also adds flavor. Yes it’s meant to be eaten! It’s the same seaweed that is used for sushi rolls.
muffin tray
Oooh. I’ve been doing this 4eva but use muffin n cupcake trays so I can place 6 clingwrap on all the holes and fill them up with rice. Its my little onigiri production line hehe. So I have big onigiri (muffin trays) with filling and small onigiri (cupcake trays) plain to pack into my bento. The little cupcake tray onigiri breaks with filling but it works well as carbs component in my bentos for uni.
PS. love your blog
This Made Onigiri-Making Easy!
I have always tried to make onigiri, but somehow my onigiri always fell apart. This was so much easier and they looked absolutely perfect! They tasted good, too! I tried tuna and soy sauce filling, which was good, and umeboshi filling. It was lucky that my friend had gone to Japan. She brought me back a whole jar full of umeboshi and it was DELICIOUS. I also made a pickled cucumber umeboshi…it wasn’t a pickle. It was saucy and good! Thanks so much! I will definitely refer this site to other people and I make this everytime I want a nice onigiri! Thanks! ^_^
Thanks for tips & some ideas for fillings
Your instructions were so easy to follow and this method worked wonderfully for me! Thanks, Maki!
It occurred to me that some unconventional but suitable, not-easily-perishable fillings could be Chinese salted eggs or Chinese fish/chicken/pork floss. Aside from buying these things commercially, it’s easy to make your own - I like the recipes for them here: http://lilyng2000.blogspot.com.
salted eggs
Thanks for the salted egg recipe! That might be a good filling indeed.
Rice molds
Because I can’t even do the plastic wrap method effectively, I cheat completely and use the rice molds that I bought at the local Asian convenience store. My only problem is I can’t really figure out how to salt them adequately, but it’s okay as my kids prefer them plain anyway. Will keep working on that!
salting
Tracy, you can try shaking a bit of salt over the rice balls after you’ve formed them also.
Really easy Method
Onigiri is so much easier to make then sushi (and it also allows for more experimentation ^_- made several of my own fillings the most successful being cut up spicy sausage) and with you method mentioned above, I’ve even got my food illiterate brother to have a go!
Thanks!
Thank you for this! It really did the trick!
Hey! I really like your
Hey! I really like your blog, and I appreciate you sharing this awesome method! I tried it, and it works great ^.^ Though, I have yet to make onigiri with any fillings, because I don’t like raw fish…I might try teriyaki chicken, but you see I want a filling that’s super tasty, but easy to make as well. So making onigiri doesn’t take so long, you know?
Lol, yeah, I really wanted to try onigiri after watching Fruits Basket. They looked so tasty and cute!
You’d never use raw fish
You’d never use raw fish as a filling for onigiri…and I never suggested it. You may be confusing sushi and onigiri (and sushi using raw fish is NOT portable).
plastic onigiri wrappers
HI! Can someone tell me how to use those plastic onigiri wrappers that separate the nori from the rice? he instructions on the package are in Japanese and I cannot read it!
Thanks!
Thanks you!
Such a great idea…wish I’d thought of it myself. Now I use my mold/press thing, but if I go back to doing it by hand, this is the route I’ll take.
YAY!!!
I’ve seen lots of references to onigiri in manga, but I haven’t been able to find a recipe that didn’t assume I knew most of the important stuff! Thanks for the recipe! (And I actually found this page while searching for fruits basket, Ha ha!) ;)
tuna salad in onigiri
I’ve quickly scrolled through to find out how to care for a tuna salad rice ball. I lived in Japan for a while and I loved eating the tuna salad onigiri’s from 7’11. Since I don’t refrigerate my onigiri when I take them to lunch how would that work with something with mayo. I always eat my lunch around 2pm, so they would sit for around 5-6 hours. ???????
To be on the very safe side
To be on the very safe side I wouldn’t really use mayo-tuna salad in an onigiri that might sit at room temperature for too long. Though I have had tuna-mayo filling (made from commercial mayo, not homemade from raw eggs etc) without problems, I don’t want anyone to sue me either if I say it’s safe :) To be on the safe side you can try packing your onigiri lunch with a cold pack.
There are other onigiri fillings that are quite safe and actually help keep the onigiri longer - umeboshi fits this perfectly. Most other traditional salty fillings are fine too. Keep in mind also that onigiri doesn’t require a filling - so you can for instance bring plain unfilled onigiri, and have a salad on the side.
