Daily Life (Both AP House and Downtown Guidance)

How much do irons and rice cookers generally cost?

At Minishare, each would cost around 500 yen. If you wish to buy brand-new ones, it should cost approximately 2,000 yen for irons and 4,000 yen for rice cookers, depending on which kind you choose.

What kind of appliances should we bring?

Other than laptops and personal devices, it is not necessary to bring electric appliances like hair-dryers, hair-straighteners, lamps, etc. because the standard voltage in Japan could be different from your country. In the end, it may cause your electric appliance to short-circuit or break. In any case, you might just find buying appliances in Japan to be cheaper and more convenient.

What kind of things should we bring from Indonesia and which ones should we just buy in Beppu?

Religious materials might be hard to find in Beppu. If you practice Islam, it will do you good to bring prayer garments from back home (sarungs, mukenas, etc.).
