I didn't see many specifics about furniture in the core book section on dwellings. Do the people of Rokugan sleep western-style in beds? I need to know how to design the daimyo's guest quarters for my players.

It's usually assumed to be futon on tatami mats, i.e. traditional Japanese arrangements.

We usually go for the japanese minimalism. Our usual Rokugani house is something like this:

A square building, often with a square of open space inside.

A set of spaces set apart by solid walls, with movable doors "to the side" that allow you to access the rooms from the corridor (which is also basically a square adjacent to most of the rooms).

"Rooms" separated by solid, durable and permanent walls are large and empty. These spaces can be separated into smaller rooms by inserting less permanent walls (the iconic "paper walls"). Rooms are empty, because majority of furniture is stashed away in the elegantly hidden closets - often a whole wall is used as a furniture closet. This is where you (or your servants) put all the things - tatami mats you sleep on, small chairs, tea sets, writing utensils, drinking sets, game sets, etc. If you don't use something right now, you put it away to not waste space. Space is precious and important (especially remembering that often multiple people live in the house), so it's much better to use the same room for writing the letters, painting, sleeping and so on, instead of having dedicated rooms with permanent furniture allocated to them. This naturally leads to the fact that most of the furniture is small, light weight, foldable and portable.

There are three big exceptions - shrines, cooking furniture, and bathing furniture. First one because of respect, latter two because they usually are "built in" into very specific rooms that also are separated from the daily life because they are kinda gross and unclean and - more pragmatically - because you can then easier heat them up . Poorer people actually tend to flock around their kitchen in winter :P.

So basically, your typical samurai guest rooms will be a set of small, utilitarian rooms "created" by inserting walls into a larger, permanent room.

It depends on the clan.

Crane sleep on the finest made mats. Finely decorated and super comfy.

Crab typically sleep on the wall, using rocks as pillows. The rocks double as weapons.
Dragon have been asleep their entire lives and are looking to wake up.

Lion sleep on the mats of their grand parents. They typically use the same strategies as their forefathers to help them fall asleep.
Phoenix sleep upon a pile of books and scrolls. Water kami are popular to clean the ink smudges on their faces in the morning.

Scorpion are concerned about that new Crane courtier spending long nights with your wife.

Unicorn can be found by their horses, sound in their slumber.

Mantis don't sleep...they wait for others to sleep so they can rob them blind and play 'real samurai' with their stuff. It can really be cute if they don't know you're watching.

Crab clan sleep when they are dead. Even then they will wake up now and then.

We use pillows stuffed with the hair of our enemies. The beds we sleep on are sewn together from the flayed skin of our enemies, then filled like a waterbed with the tears of their children.

Well, I guess jade is technically a rock...

Jade's too valuable to be used as a pillow; instead they stud their mass produced tetsubos with it.

Battle maidens sleep with their horses.

While their husbands sleep in the stables...sad part is I'm only half joking.

I admit that my first thought here to "Crabs sleep on the wall" was "I guess if you tie some string to their pincers and hang them between two nails...", and my second thought was of big armoured bushi sleeping standing up but leaning on the wall, because if they lie down properly it'd take 'em too long to stand up again.

Didn't you hear? They wrote Daigotsu with plot armor against sleeping, so the Spider Clan never have to sleep. How else are we going to find the time to ruin the game?

...I might like you, Spider...just a little.
