A wooden bento is doable daily if you treat it right.

You can absolutely use a traditional wooden bento box daily, but it’ll need more babysitting than a plastic one.

Those hinoki or cedar boxes are gorgeous, and the wood actually helps keep rice and dry foods pleasant longer. But wood is porous, so it will stain, smell, and crack if you’re careless. The maintenance is simple, just not optional.

Hand wash with mild dish soap and warm water. Don’t soak it, don’t put it in the dishwasher, and dry it immediately with a towel. Then let it finish air drying completely before you close the lid. Storing it slightly damp is how wood warps and gets funky.

The bigger thing is what you put in it. If your box has a lacquered finish (many traditional ones do), it’s more forgiving. If it’s raw wood, keep it away from tomato sauce, soy-heavy dishes, and anything greasy for extended periods. Saucy foods in an unsealed box will leave ghosts.

When the wood starts to look dry or pale, give it a light wipe with a food-safe oil — camellia oil is the classic, but mineral oil works too. Just a few drops, rub it in, wipe off the excess. Do that every couple of months or during dry winters.

Honestly, daily use is fine if you’re the kind of person who enjoys small rituals. If you’d rather toss a container in the dishwasher, get something plastic or steel. Wood rewards attention, and it degrades if you don’t give it any.
