Bento 101 (Getting Into the Bento Making Habit): Part 2b: The right kind of bento box for you

Bento supply display shelf in local Japanese supermarket

Welcome back to the 3rd lesson in Bento 101: Getting Into the Bento Making Habit. If you’ve been following along, by now you should have a list of foods you like to eat that you consider to be packable for lunch, as well as experimented with putting a meal in a box. If you’re just joining us, there’s still plenty of time to catch up!

In Part 2b we’re going to continue thinking about the all important question of the container or containers we want to bring our lunches in. The type of container that is ideal for you depends primarily on the types of foods you want to bring for lunch. This is one of the main reasons why I had you make a list of foods that you’d like to pack for lunch in Assignment 1. The food you want to pack should dictate the type and size of container you need, not the other way around.

So let’s look at the container types to consider.

The Japanese style bento box


Japanese and Japanese-style (since not all boxes of this time are actually made or designed in Japan these days) bento boxes are a marvel of compactness and portability, and are available in a wide variety of designs, colors, materials and price ranges. And let’s face it, they are the most fun to collect. (Take a look at my visit to Hakoya, the largest bento box maker in Japan for example, to see the care they take in making even mundane plastic boxes.) Japanese style bento boxes are available in sizes ranging from around 250ml capacity (about 1 US cup) to 1000ml for single-person use. Most bento accessories such as silicone cups for dividing up your food inside the box are sized for Japanese bento boxes.

One third to one half of a typical Japanese bento box is packed tightly with rice. Besides the rice there are usually various other foods called okazu that go with the rice, also packed in tightly so that the food doesn’t shift around when the box is in transit.

This is a classic Japanese style bento (how-to here):


If you like Japanese style bentos anyway, naturally the bento boxes designed to hold them are ideal for you. They’re also well suited for any kind of meal that’s based on some sort of cooked grain or beans, not just rice. Think of couscous, quinoa, barley, lentils, whole wheat berries, a mixed bean salad…the list goes on. The larger sizes are great for pasta salads that use short pasta, as well as potato salad and so on.

Here’s a fairly small bento box filled with quinoa and beans (how-to here):


Here’s a pasta salad in a larger-size (around 700ml) Japanese-style (but not actually Japanese) box (how-to here):


Most of my boxes are Japanese bento boxes, since most of the bentos I pack (as well as the ones featured on this site) are based around cooked grains or legumes of some sort.

The bento size guide is especially useful for this style of box. In most cases you’ll be packing your lunches tightly using the ‘third dimension’ as we covered in the previous lesson, so if you haven’t done that assignment yet I’d encourage you to do so before going shopping for the bento box that’s right for you.

One thing to note about Japanese style bento boxes is that they are designed to be carried upright in your bag, with the lid facing up. There are even ‘slimline’ boxes that can be packed upright in a briefcase. This means that your lunch will not leak out in most cases, especially if you choose a box with a sealing lid. Most modern bento boxes have sealing lids, but a few don’t, such as traditional wooden boxes. These just need to be carried with extra care if you pack something leaky in them. Furoshiki or square cloth wrappers are traditionally used to wrap around such bento boxes tightly. (If you’re crafty, take a look here for long time JustBento friend Bronwyn Carlisle’s instructions for making your own furoshiki.) An American box like the LunchBots line which have non-sealing lids can also be used like this with leaky foods. There are also dedicated bento box bags, some of which are insulated.

Thermal bento containers/lunch jars


Thermal containers are great if you like the idea of a hot stew or soup for lunch, and don’t have access to a microwave at lunchtime. I took an in-depth look at themal containers here.

Personally I am not the biggest fan of the large, bulky thermal lunch jars like Mr. Bento, just because they’re rather heavy and bulky. I prefer to use small thermal lunch jars for the hot/liquid stuff, paired with a regular bento box for the other things. But The Guy (aka my husband) loves his Mr. Bento, and I know that the all-in-one solution has a lot of fans.

This is a meatball stew bento that The Guy made using a thermal lunch jar set. (how-to here).


Larger containers or multi-containers for fluffy food lovers

By “fluffy food”, I mean food that needs quite a lot of space and air around them, that would suffer if pressed into a compact container - in other words, things like salads and sandwiches. There are two approaches to this type of lunch packing situation: to choose large, roomy containers, or to use multiple containers.

For sandwiches, I often make a ‘deconstructed’ version, where the bread is packed separately from the fillings and are assembled just before eating, like the deconstructed bahn mi bento, where I’ve used a regular Japanese style bento box to pack the fillings plus extra salad:


For this even simpler deconstructed sandwich I also used a regular Japanese-style box for the fixings:


Here’s another deconstructed sandwich, where I used a bento box that is way too small (at around 350ml capacity) for a regular bento, but works great to hold the fillings for a sandwich plus fruit


If you’d rather bring an assembled sandwich though, there are plenty of sandwich containers out there, from the plain plastic bag plus brown bag combination on up.

If you like eating leafy salads and the like you will need a larger container, and the sizing guidelines listed above won’t really apply to you. While there are dedicated ‘lunch containers’ for this purpose, you’ll find the a much bigger choice by looking at regular food containers. The larger, deeper size of Ikea 365 container for instance is not too bulky, but is deep enough to hold a good amount of salad - and you can use the smaller capacity models in the same line as side boxes.


You could also pack a salad lunch in multiple smaller boxes as Idid here - the leafy greens in one box, a potato salad in the smaller box.


Fixed compartment lunch carriers

There’s another category of lunch container that I haven’t discussed too much on these pages, and that’s the large, multi-compartment type of carrier, such as the Goodbyn Lunchbox or the PlanetBox. The advantage to these containers is that initially they seem easy to use since the compartments are so well defined. I am not sure if any were inspired by the muffin tin lunch movement, but I wouldn’t be surprised since the concept is similar.

The drawbacks that all of these containers share is that they are quite large and bulky, and can only logically be carried vertically unless you have a shopping bag or something with a very big bottom. If you have food a very ‘wet’ food with sauce or something in there, if you carry it vertically there are good chances it’s going to leak, no matter how leakproof the manufacturers claim their carriers are. They usually try to prevent leaking by fitting these containers with tightly fitting lids that may or may not be hinged, but it’s hard to fight against the laws of gravity. Most Japanese style bento boxes are designed to be carried upright with the lid facing up, so they are much less likely to leak.

Therefore, in my opinion the large, flat lunch carrier is most suited for people who do not pack ‘leaky’ foods. If your lunch style is some cut up fruit and vegetables with hummus or cheese cubes and some nuts and raisons and so on - which is the kind of lunch that tends to be featured in the marketing materials for these containers - then they are great.

(Note: I’m not sure what to make of the current form factor of the Laptop Lunches line, which I now notice are being marketed as ‘bento boxes’. I seem to recall they used to be bigger in height and width, but now it looks like theyv’e made them smaller h x w wise and deeper. The current stated size is 9” x 7”, which could be carried upright at the bottom of a roomy backpack. Any Laptop Lunch owners out there that want to comment?)

Choose the right material

This chart of bento box/container materials shows you the pros and cons of each type. For instance, glass is great if you are looking for something that is plastic-free (although the lids are usually some sort of plastic) and dishwasher and microwave save, but does have the considerable disadvantage of being breakable, as well as heavy. Stainless steel is dishwasher safe and plastic-free, but can’t go in the microwave. Wood or lacquerware should only be used if you’re willing to commit to their high maintenance. And so on. (If you’re concerned about BPA, see this article also.)

When you are selecting the right type and size of container for your style of eating, you may be tempted to use containers not meant for food use. I wouldn’t recommend doing this at all, since you don’t know what is in the plastics used, not to mention any coatings or paints.

So, this leads us to this weeks assignment:

Assignment 2b: Select the right lunch container(s) for your eating style

  • Go through the list you made for Assignment 1, and determine which kind of lunch you’re most likely to pack. Is it compact and grain-based? Do you want something hot or soupy? Maybe you prefer packing salads and sandwiches?
  • Choose the type of lunch container that is the best fit for you based on your preferences.
  • Now the fun part: go look for the box that’s right for you. For Japanese style bento boxes in particular, the Where to shop page is a great place to start - it lists the wonderful bento box sellers that support this site and keep it alive and kicking. Readers in the U.S. can also try looking through the ever increasing selection of bento boxes on Amazon.
  • If you can manage to get your bento/lunch box by next week, great! If not, try to have a backup/substitute box ready to go. We’ll be packing our very first bento for the next assignment.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I have both the old and new Laptop lunch boxes. They are the same size, about 6.5"x9". The only difference is the inner dividers. I like them a lot, but always try to carry them upright. They do come with tops for some of the containers, but everything shifts and something like soup would definitely be too risky.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

American shoppers may want to take a look at We have been very pleased with our purchases from there! The website is a little difficult to use and the selection is not huge, but the prices are great and it makes a good place to shop for a first bento!

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

Have you come across Tiffin carriers - that was my goto luck carrier until I broke it, and they are no longer stocked locally. :-(

Loving the series!


Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I do have a tiffin, but it's way too big for one person. There are tiffin like stacking stainless steel containers around that are smaller though, and lunch jar sets like Mr. Bento are similar stacking type containers. I talked about tiffin type containers briefly when I did an in depth review of stainless steel bento boxes.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

The tiffin box was big, but it was great for 'fluffy food' - my current bento doesn't handle lettuce very well. Also , I could pack lunch and breakfast :-)

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

Hehe I have already planned next years xmas list!!! I am going to ask for a bento box and other supplies :) but until then Ill be sticking with the handy lock n lock boxes (teehee)

Very informative BTW just what I have been looking for! Im a salad person so I may pair a small japanese style bento with a seperate salad container.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

A fan of lock and lock here too. I pack leaky food like stew and curry often. I also use a tiny one for yoghurt. Never had it leak even though they might be sideways in my bag. Problem is I can't find the right size for my lunch. I'm using 870ml and it's little too big. Would love a 600ml but couldn't find one, yet!

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I do believe we may have a 600ml one! We have soooo many! We buy all of ours in costco- maybe you could try there if there is one close by? Check the big multi sets (they contain a variety of sizes in one big box) we have a few of those and I think the 600s came from one of those.
Hope this helped!

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

In Canada (and probably the US too) there are two major companies that sell high-quality plastic containers, Tupperware and Rubbermaid. They are great for storing leftovers in the fridge, and I find the smaller Rubbermaid sandwich containers are a perfect size for a bento lunch. Both are leak proof, and Tupperware has all sorts of cute tiny containers. If I make something that is runny or liquid, I can put it in a small container to bring with me, like salad dressing to add to my salad at the last minute.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I've been using Rubbermaid LunchBlox for my bentos, and I'm fairly impressed with them. The idea is different sized and shaped plastic boxes and ice packs that snap together like LEGOs. This gimmick doesn't really work well with the smaller boxes, but it's great for the bigger ones. The snap-in cold packs are especially nice, although I think I'll need to order a couple more - summertime bentos will need more than one.

They sell them in kits and as individual boxes. I started with a sandwich kit. But all the containers were giving me fits, so I swapped all the little boxes for a second sandwich box. This gives me two 615mL containers that snap together, and it's just about perfect.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I'm so jealous of places that have Bento box stores! I have to buy mine on the internet and it's so expensive! I wish I could go to a store that has them all over the place like that first image! :S It's tough finding them where I live... And I love the traditional kind, I don't want to use plain tupperware

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

Maki gave me an excuse to go shopping for a new box! Best course EVAR. I've been itching to try a two-tiered box.

I have two bento boxes, both of which I like. I use the Mr. Bento lunch set for all-day-long eating. It's handy because I can pack breakfast in one container, two snacks in another container, and lunch in the remaining two containers (or another combination thereof). It's pretty rare when I've used it for its thermal qualities! It is large and bulky, but that's not much of a problem for me. I just slide it in my big backpack and go to work. Plus the little bag it comes in is perfect if my backpack is already stuffed full (with motorcycle gear, mostly). I'll post on the flickr the way I've used the Mr. Bento.

After I experimented with doing a bento-style lunch, I wanted something more "horizontal" so I can pack a lot of little things in one box instead of filling each Mr. Bento compartment with one thing. I got the Lunchbots for this - the Uno is perfect for a bento lunch and I can use the Trio or Quad for breakfast and snacks. It's also handy for when I know I'm going out for lunch and just want breakfast, or just doing a half day or whatever. I rubber-band the lids and that helps with the leak potential.

As for foods in my bento box, I love using leftovers and want to get better and making planned leftovers in bentos. Even before I started making bentos, I'd throw whatever leftovers I had in my backback for lunch. It seems so natural. So I want to buy with compact foods in mind.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

Hi all
got a good start on bento boxes as I already had 2. Photos can be found Here
The one Stackable looked alittle big but one of the photos will show my packing plan.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I have 2 bento boxes but this is the one I'll be using tomorrow. the other is a lock and lock one.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

Hello! I updated the 2A pics on my blog, so I think they should be working now.

And, here is the link to 2B.

Thank you!

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I have Both old and new Laptop Lunchboxes. I compared their sizes--the old one would hold an even three cups of food. The new one holds more, and has more inner lids. It can go sideways, as long as whatever is inside is not too liquidy. Generally I do try to keep it flat but I don't sweat too much if it gets tipped, especially to new version.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I found out that I'm richer than I thought I was. Apparently I have 2 bento-boxes:
a box-appetit (easy for salads and stuff)

a hamburger box (fun one)

Of course I will go for a third one. In Belgium it is not easy to find bento-stores, but I'm not giving up :)
I'll be looking for a multi-container. I like to take lots of different foods to work.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

It's a bit of a photo-bomb post as I went through all my bento/lunch boxes, but here's my assignment for 2b:

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I love my Laptop Lunchbox, and I've never had a leak. I do recommend packing leaky foods in the small inner box with the lid.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I have three "boxes" that I use, depending on what I've got for lunch.

First I bought a Mr. Bento. It's good for wet leftover-based meals, and the bag is nice (pockets for tea packets, space for a cloth napkin, etc. each container isn't as leak-proof as I'd like, but since it's inside a tube it's not generally a problem. If I pop the outer "tube" in the freezer before I pack my lunch, cottage cheese or yogurt stay COLD until lunch. I really like the Mr. Bento.

I also have a snap-top rectangle container for lunch salads. I can make a HUGE salad in it, along with a plastic container or dressing and/or crunchy bits, and it goes in a backpack just fine (no leaks, since it has a silicone gasket).

And, finally, I just got a Laptop Lunchbox system. I love it. It is remarkably easy to pack a very healthy lunch (with snacks!) for a full day of work. The little containers for wetter things have, so far, been leak-proof. And one could not use the containers if desired, but I find it's easier to have the four compartments. And, there are other sized containers that you can buy if you want more flexibility (so far I'm fine with the basic set).

Loving this series of lessons! Thanks so much.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

The container store also has some interesting possibilities.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

That photo looks like it is out of the Daiei! It brought back wonderful memories for me of when I lived in japan in 2003. Hopefully I will go back there sometime...

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

It's actually the 'new school year bento' display at an Aeon supermarket. But many stores have similar displays up around this time of year until about mid-April or so.

Re: Bento 101 (Getting Into the Bento Making Habit): Part ...

I was in TJ maxx the other day and I saw they had "bento boxes". They were a little larger than the ones I bought from daiso in california but cute. They also had little square lunch boxes that could be a bento.

Also, you may have some luck finding bento boxes in 99 cent stores run by Chinese people(but they're not all 99 cents), or asian supermarkets, etc.

I live in NYC btw. There may not be a store specifically for bentos only but you can find bentos in many strange odd places. :) I even found eggmolds! Also indian grocery stores have cute tiffins that can serve as a bento box :)
