Put cooked rice in your bento box about 3/4 of the way full (leave some room at the top for your toppings and to be able to put the lid on).
Take 1 umeboshi and put it on one side of the rice.
In a small pan, heat the oil on medium-high. Cook one shishamo on both sides until cooked.
Place the cooked shishamo across the middle of the bento box on the rice.
Boil water in a small pot. Put in a handful of frozen edamame and cook according to package instructions.
Once cooked, pop the edamame beans out of the pod. Arrange them on the rice to fill up a little less than one quarter of the bento box, under the shishamo.
Sprinkle the sakura denbu on the rice next to the edamame.
Enjoy whenever it's lunch time! Put a lid on it and pack it away to take with you.
