Hi! Thanks for your recipes. I notice that you use different bento boxes in your pictures. Do you have a recommendation for any one in particular that can be easily opened by big and little kids?
Hi M J, Thank you for reading Nami’s post!
Here are Nami’s bento-making tools and her favorite bento boxes.
How about LunchBots or MONBENTO?

If your little ones can twist and open the container, THERMOS or Zojirushi is perfect for keeping food warm until lunchtime.
Either way, we recommend choosing the size that kids can easily finish eating.

Hi Nami! Do you have to put an ice pack for these bento lunches when taken to school for lunch? Or food will be okay without it and just eaten in room temp? Thanks!
Hi May! Thank you very much for reading Nami’s post!
It depends on where you live, but we recommend using an ice pack to keep the food safe.
We hope this helps!

Hi Arthur! Thank you so much for your kind and encouraging words. They meant so much to me. You also seem like you started sharing your online food journey too. Good luck! 🙂
Can this food be kept hot
Hi Susan! It can be kept warm if you use a thermal lunch box or jar. But in general, bento is supposed to be enjoyed at room temperature. 🙂
I love your recipes, the justonecookbook is so easy to use, and looks so pleasing to the eyes.
When you look at the top of the page you have;
RECIPE INDEX, COURSE, DIETARY, INGREDIENT, PREPERATION, TYPE, FAVORITE, HOW TO.
I love this, it’s so easy to find what I am looking for and if i don’t find it there I easily find it at the bottom of the page where you have Browse popular topics. I did however notice 1 thing I couldn’t find unless I actually searched for it. Your Bento recipes. So I was wondering if it was possible to add BENTO as a link under your COURSE in the top of the page? so it becomes like this:
COURSE:
APPETIZER
BENTO
BEVERAGE
BREAKFAST
DESSERT
ENTREE
SALAD
SNACK
SOUP + STEW
This is only a suggestion so that it’s easier to find school lunch box, or back to school food, or lunch box, bento, whatever you want to call it. A easy to find for all parents who make their children home made lunch boxes, and/or students who want to make their own lunch boxes.
I don’t have much of a imagination in the way of lunch, I live in Norway and apart from amazing warm dinner time, we eat a lot of bread, out lunches are not very balanced and so when I stumbled over the concept Japanese Bento, I was so surprised that lunch could look so good. My normal lunch is 2 slices of dry bread.. Bentos are amazing and should be advertised as it provides such a balanced meal.
This is again just my suggestion since I was so blown away by the amazing lunch boxes and though others might find an amazing concept as well. Please don’t feel pressured to do this if you do not want to. I just felt I had to ask.
Thank you for sharing your wonderful recipes her on justonecookbook, I am very grateful.
Hi Karen! Thank you for your suggestions! I wasn’t aware that bento wasn’t listed, so I’ve added Bento under “Favorite”. 🙂 Thank you for your kind feedback. I’m glad you discovered bento making! 🙂
Nice bento! Just wondering are they served cold ? Since they are supposed to be eaten at school? Or how do you keep them warm for food safety reason?
Hi Yvette! Japanese bento is always served warm. Even at the office, some people don’t microwave it (after all years of eating bento during schooling). We use ingredients and food that taste good at room temperature (hence seasonings tends to be stronger/saltier). IF you want to keep your beneto warm, make sure it stays warm all the time. Use a thermos to make sure food is well kept hot/warm. 🙂
Hi Nami, I love bento boxes but if I make it, I have to make it the night before. I don’t think you heat it up or warm it up when you eat it, do you? Then the rice can be drier and stone cold. Do you always cook and prepare them in the morning?
Jo
Hi Jo! Rice gets really hard when it’s stored in the fridge. So I do not recommend to do that… but if you REALLY have no other choice, then wrap the bento box with a thick kitchen towel and see if you can prevent the bento to be too cold but keep cool. That’s what I do when I make sushi and have to keep them in the fridge, but I don’t want my rice to be cold.
In my case, I usually use leftovers or frozen food that I cooked previously, so I always reheat using a microwave, toaster oven, or in a frying pan (depends on food). I rarely cook something from fresh, maybe except for Tamagoyaki when I don’t have the frozen batch. Or some frozen veggies to stir fry to pack in one area that needs just one more dish… Japanese moms (in Japan) deep fry in the morning for bento etc, but I don’t. 😀 Unless we eat rice for breakfast, I reheat my frozen rice in the microwave, and pack in the lunchbox. It’s easy, BUT the food needs to be cool before closing the lid, so I have to wake up early for that (I prepare bento before preparing breakfast). Hope this answered to your question?
Yes you did, thank you so much! You are always so good at responding to questions and providing detailed information, much appreciated!
My family and I just went o Tokyo for the first time. One of my inexplicable desires was to eat a bento on a train in Japan, and I did on the Romance Car from Hakone back to Tokyo. It looked gorgeous and was much more delicious than I expected. It was one of the highlights of my trip, hahahaha….
Jo
Hi Jo! I can totally relate as I look forward to eating obento (and snacks) on a long-ride train (I mean, it’s bento that you don’t have to prepare and so many kinds!!!). 🙂
Glad I answered your question. Your words are too kind. I actually struggle to respond “in time”…. many people wish to get my answer right away (while/before they are cooking) but I am always behind and emails just accumulate… :/ I’ll do my best!
What bento lunch box would you recommend for young kids to take to school??
Hi Heidi! When my kids were smaller, I was using Japanese lunch box (smaller and cuter). Once they are in elementary school, I pack in LunchBots.

Hi, i’m from Brazil and i love asian food, this site is amazin! tonight i gonna make gyoza dough!
Thank you Barbara! Hope you enjoy(ed) the gyoza dough! 🙂
Hi Nami,
Can you talk about these Bento box you used here? They look small which will be suitable for my preschooler. thanks
Hi Zoie! I’ve used these bento boxes for my kids when they were younger. The small bento boxes are from Japan (or you can buy online or Japanese supermarkets etc) and the lid has a character (Thomas etc). 😀
I just love bento, wish we had heard of them when i was a child although my mum was not into cooking so i still would have probably gotten a boring sandwich.
Hi Linda! So happy to hear you like the concept for bento. I think even sandwich makes it wonderful bento too. But need other than sandwich to make it look appetizing etc though. My bento was always simple growing up – no character bento etc but my mom added different colors and textures to make it more interesting and delicious. 🙂
