Japanese or Chinese coin?

Hi,
I bought these coins last Saturday. The guy I bought them from said they were Japanese. But is this the same kind.

i'm totally clueless about them, sorry. but welcome to the forum!
Here is an interesting link with some excellent pics of the coins in question:
Japanese coinage in East and Southeast Asian trade in 17th century
I never would have thought that cash coins were internationally exchanged.
Sure they were worth something within the empire on the Emperors say so, but being made
of base metals and easily copied I figured that would have been the extent of it.

A few more questions. How much are they wreath? Are they rare? And is there a safe way to clean them? I've never collected coins before so this is new to me.
Welcome to the forum, by the way! Japan has an unusually great and diverse numismatic history, many great designs and several oddball shaped monies. I think you'll find much to enjoy if you stick with collecting it
Krause's Standard Catalog of World Coins is the book collectors usually go by for general stuff. It's nearly fully illustrated and comes in a different volume for each century back to 1600 with general valuations for each coin. JNDA is the specialist catalog for Japanese coins (it's mostly in Japanese though!).

I think I'll be collecting Japanese and Chinese coins. But mostly Japanese. I'm hooked on anything Japanese.
You can tell I just found the Emotions tab.
