Does the desk have any marquetry? Carvings? What joinery was used?

Don’t leave us hanging!

Japanese joinery is a week-long rabbit-hole in itself. It's basically witchcraft.

Nowadays Japanese joinery definitely keep me entertained for a couple of days. I would imagine adding the historical and geographical components would make it an infinitely entertaining dive !

Just write a prologue with a 13C Japanese cabinet maker starting making the desk.

Then, write the epilogue with the cabinet maker finishing the desk.

Then fill in the bits between.

Definitely don’t watch Ishitani Furniture then.

Would they even have desks in 1200s Japan? Seems like they did everything on the floor back then.

You're going to make her start over!

On the other hand, I can get really annoyed when writers get stuff like that wrong. Especially when it's crucial to the plot and it happens to be within my area of expertise. So I do appreciate writers that do their research.

I've consulted on a couple of books and I've seen two kinds of fiction writers. The first one simply starts writing and only stops once the story is done. They might get writers block in between or reorder some stuff in editing (if they do editing, some don't), but mostly the story is written from beginning to end in one go. The second one is the one that does plenty of research beforehand. They might have an idea of the plot, but it's more of a concept and not finalized. They start building plot points, characters and story lines. They decide on things like structure, pacing and point of view. Small details crucial to the plot get thought out and researched before hand. They write the important stuff first, then fill out the rest and make sure there is a natural progression from one point to the next. They make sure everything fits within the designed character profiles and backstories. Often they edit a lot and entire chapters get deleted and rewritten. This is the kind of writer that works with others, sometimes multiple primary authors, often other people that do the editing.
I vastly prefer the second kind and love working with those people. I feel like they write better books, regardless of how much time it costs them or how successful their books are. But a friend of mine is the first kind and he's had some success with his books. He likes to let his creativity flow and outputs more books, so more chances of capturing an audience. But I do feel you sometimes need to turn your brain off a bit to read those kinds of books.

I can get really annoyed when writers get stuff like that wrong.

I was reading a science fiction novel and just about every time a gun was fired in a vacuum the author included some detail about how the weapons were "vacuum sealed" or some such thing, so that they would fire without oxygen.

...except guns work just fine in a vacuum already. All modern firearm propellants (and many historical ones) are self-oxidizing and don't rely on atmospheric oxygen to burn.

It snapped me right out of the book every time I came across it.

I mean …. Chat gpt?

Stop outsourcing your brain

How about stop wasting time on mundane details that would take a human hours but can be easily be done by an ai in seconds? Honestly your time is better spent elsewhere.

Getting a historical detail correct in your literature project isn't "wasting time on mundane details". Having arguments on the internet is tho

I don't trust current AI tech to actually process information and logic correctly. Just because it has figured out how many Rs are in "strawberry" doesn't mean it is always (or even mostly) correct

Desk? If anything a low table or directly on the floor.

Edit: ok, wasted a little time on this. It probably could have been the floor. Tables were likely used for shodō, but purpose built tables weren’t common for writing until the late 1300s. They weren’t “desks” by any modern measure.

did genAI tell you to ask that?

What kind of rugs and floor coverings were common at the time?

I'll admit that I'm staggered by how a lot of writers absorb hundreds of little details of how trained soldiers/detectives will use little tricks to survive, observe a room, or follow patterns of criminals. Once long back, those little things like leaving a bit of pencil graphite in a door hinge to denote intruders (or, in Better Call Saul's case, placing a carbon sheet under the doormat) were extremely rare to hear about.

I don't even know who you'd ask without ending up on a list.

I think a lot of writers are probably on lists of various types.

how do you know that's not where they started their research?
