>>8006368US Based, I just bought a kotatsu from
https://futon-japan.com/collections/kotatsu/products/japanese-kotatsu-75x75?variant=36614101205155, arrived in like 3 days. Its US voltage compatible unlike the others that are 220 voltage.
Got one of those baby soft foam playmats that cost like $120USD and then a kingsize fleece blanket for $50 (was on sale). Its been super comfy and difficult to remove myself from.
