Magewappa means bent woodware; it’s a traditional hand craft of Odate, which is located in Akita Prefecture in northern Japan. Straight grained pieces of Akita cedar are bent in circular shapes to form the sides of containers. The bent wood is then fastened with a contrasting dark bark or wood strips.
There’s been a resurgence in the popularity of magewappa ware, so it’s made around the country, but this box comes from Akita, where I think the craftsmanship is still the best.
The handmade, made-to-order magewappa bento box, designed by Yoshinobu Shibata, is oval in shape with a divider inside. It’s unfinished wood, but there’s no fear of it rotting since the Akita cedar is so durable. It also has a lovely smell which seems to enhance whatever is put in it. (I don’t have this exact box, but I have an Akita cedar bowl which still has a very faint woodsy smell.) You do have to take care of it by washing it separately and drying it well between uses, but it should last forever if handled gently. (Edit: see more about Akita cedar here .)
I think that the shape looks very modern, even though it’s a traditional shape. Rice eaten from this box would be wonderful, since the unfinished wood absorbs any excess moisture. I might be tempted to carry any oily or saucy food in another container though.
