Ok, so I admit I have made slight investments into cooking in Japan, but believe me almost every item was well worth the purchase! I buy almost all of my stuff from Jusco and Daiso.
Toaster oven (~￥3000)
Stovetop grill (￥1000)
Electric mixer (￥2000)
Big IH Pot (￥2000)
Frying pan (￥1000)
Springform pan (￥1000)
20 x 20 x 5 cm square pan (￥1000)
Heart pan (￥700, and no, you don’t actually need this, I just like cute stuff)
Gratin dish (￥315)
Please note that I obviously am not a professional, especially since half of my kitchenware comes from Daiso (the Japanese equivalent to the dollar store).
