It looks like a chest made in the China trade probably during mid 18th cntury through the early 20th. The wood crafting is excellent and somewhat stylized and almost abstract. its interesting but could be early 20th century craft work)
I could date it more precisly by looking at a closeup of the cabin corners. The China an Japanese trades had several different kinds of stylized jointery , using very complicated sliding joints on the corners, and since we dont see any evidence of dovetails (since the woodcarving lies atop the corner buttings) sveral joint patterns introduced during the Mid 1800s and , japan's an Chinese butt joints were more unique each to themselves.
meiji jointery usually used 3 serpentine cuts where the joints were "Slide in" and tgese kind went during 1840 through erly 20th cntury.
The brass lock is a little skanky though, it looks like a cheap rplacement because oriental brass hinges and lox were rather massive and were often used as design inspiration for ARts n Crafts stuff where hammr marks were considered a sign of craftsmanship.
That little block of wood in the second picture. Im no xpert but I do some "picking" for antique auctions, Ive seen those things being sold as "pillows". I dont know about the on you show but its not gonn give "my Pillow" guy an competition for comfort.
Most of theSamurai "pillows" are now being used for collections or even as doorstops.
heres 2 or 3 orintal antiquitis xpwrts on Antiques Road SHowm both the Brit and the US versions an these guys are very highly experienced because a lot of China trade goods and dynastic stuff) is being repatriated back to China and some for vry high prices (like JAde pieces or bowls and netsuki (japanese kimono "buckles" and especially horn or ivory pieces)
In any case Its a really nice looking chest (it would be a better offereing were it not been previously re lacquered
