Thermos released a new vacuum-insulated jar product, "Lunch Box for Cooking Rice" (JBS-360) on September 1st. As the name suggests, if you bring raw rice with you, you can eat other cooked rice at lunch time.


It's a dream product, but maybe it's just a small rice cooker ...? I was curious about various things, so I tried using it immediately.

The lunch box that can cook rice includes a heat-retaining case, rice-cooking parts, and a special pouch for carrying. It seems that one serving (0.7 go) of rice can be cooked, and the appearance is the same as the conventional lunch box and soup jar.



First, remove the rice by referring to the scale of the middle container, and add water for cooking rice (unwashed rice can be left as it is).


Next, attach the rice cooking parts and heat in the microwave for 8 minutes (in the case of 500W). It seems that it will be more delicious if it is flooded for 20 to 30 minutes, but this time I omitted it assuming the morning when there is no time.




Take it out, put it in a heat-retaining case, change the lid and keep it warm for 30 minutes, and you're done ... it's super easy!


Thirty minutes later, when I opened it with excitement, I saw some other freshly cooked rice . I was worried that the core would remain or become messy, but it was as delicious as cooking with a rice cooker. The finish is a little crisp, probably because it wasn't flooded, but maybe it's the first time I've had such a delicious meal in the office.



Also, it is a nice point that the rice does not get cold forever due to the heat insulation case with vacuum insulation structure. Even when I opened it 2 hours later, it was as warm as it was at the beginning (the heat retention effect is 6 hours).

By the way, 0.7 go is enough for a bowl. It may be a little more for women, but there is no doubt that you can eat more than usual with the magical power of freshly cooked (?). Also, if you use it instead of a rice cooker for living alone, you can save on electricity bills.


A lunch box where you can cook rice that you want to call a "portable rice cooker". The suggested retail price is 6,000 yen (excluding tax), and the color is white as well as black.
