what are the best japanese futon beds I can buy japanese hand made with a website?

want to buy futon bed in Japan as it hard to find a good guide which is best sites as I don't really trust Amazon America for futon bed I want one from Japan made with high-quality cotton.

I feel America beds are kinda sad over price and a lot of them hurt more your back joints then futon in the floor that will not sink and will still have a long lasting bed with no metals parts inside of it.

I only have found one site that says and it made from Japan handmade is this the only good one out there?
www.futonbedsfromjapan.com

Although these futons are made in the USA, they're made to be Japanese-style, and I got my futon from here a long time ago:

J-Life International: Shikifutons, Kakefutons, Zabutons

I've had mine for over seven years and I still can't imagine wanting any other type of bed! When I finally want to get a new bed, I'm sure I'll return to this site for another (although I'm happy to see another site like the one you offered).

it kinda hard to use as mine is 3 part full set as your site how do I make a complete set?

The long-established store of Japanese futon is Nishikawa industry.
This company was founded in 1566. This company started selling futon in 1887.

I do not know whether I am selling overseas from Japan, but it is a mail order site of this company.
