Question: does it burn butane?  Does it come with butane?
Document: This is a nice little portable tabletop grill, with design, build quality and performance equivalent to the Iwatani 35FW portable butane stove, which in my experience is a &#34;best in class&#34; product.BUT ...Buyers should be aware that this grill is not imported or distributed by the Iwatani Corporation of America, nor has it been certified to meet any US standards for this type of appliance. I don't know if that means that the grill is actually &#34;dangerous&#34; to use, but it does mean that if you have any problems with the grill, you are pretty much on your own.
This may not be a problem for purchasers who have used one before, or are perhaps a bit adventurous, or simply find the grill intuitive to operate, but the many &#34;Hazard&#34; and &#34;Warning&#34; type caveats sprinkled through the instructions booklet may give some folks pause.So if you decide to order one, do it with your eyes open, aware of the possible drawbacks and liabilities. Personally, I like the grill, and think it will come in handy when I need a very portable, non-electric appliance to grill, broil or toast, say for a picnic or camping, or when the power goes out.
We love to cook food at the table , Mongolian hot pot , fondue , sukiyaki, Korean barbecue .... It is our favorite form of entertainment. For skewered meat , it is a fantastic way to cook at the table . The heat is adjustable , you can raise the grid 3 different heights . It is easy to clean . you need to remember to add water on the bottom tray so that you won't have to clean burnt residue .spray the grid with Pam  and soak it overnight to get the burned bits of.
The manual is in Japanese with pictures , but it can be mastered intuitively . It is not too big  so it will not  take too much space on the table , I did have 8 skewers of pork satay  on the grid . It was cooked through , with a little char . I use  an Iwatani canister that I bought online at veryasia $17 dollars for 8 canister and shipping is 5.99 . They do not charge you and arm and a leg for shipping .It is  my new favorite gadget . This is a Iwatani quality product, that can be adapted tto different styles of food.
If you haven't used Iwatani products before, they make top quality products. I tried in vain to find in the US. It is super fun and economical to use and can cook quantities more than you might think. Works perfectly.
I bought this for new year's day party and it work great. Easy to clean up and construction was not cheap very solid design.
Flames are strong so be careful of wooden skewers getting torched. Instructions are all in Japanese but the diagrams are pretty much self explanatory. Wish it were a little bigger. Cooking takes a while. But flavors are tastier than a frying pan.
Amazon might take the grill back as a return, but Iwatani Corp. of America won't be there for you.As others have pointed out, the user instruction booklet and other printed materials are Japanese-language only, although there are plenty of cartoon (pictograph?) illustrations to go along with the Japanese text. Those illustrations are a big help in getting the grill up and running. My guess is that it is unlikely that there will ever be a translation, or at least a useable one, if the title for the Amazon listing, &#34;Iwatani Gen. Abu Bata home furnace I (Ya roasted)[Grilled skewers only a cassette-type gas-]CB-RBT-A&#34;, is any indication.
