Right from Japan:


Japanese ceramic grenades. Made from porcelain due to metal shortages. Simple but effective grens.

hehehe.. sorry.....

Its a Japanese Type 88 pottery handgrenade made of terra cotta. There are several variations.... They are WW2 era. They had a match type composition fuze and were wrapped in a waterproof rubber sack after being filled.

I guess you could call these grenades Japan's version of ersatz. Funny but it seems that all combatants in most wars had ersatz in one form or another as, for whatever reason supplies of raw materials dwindled. Be it blockade or whatever ersatz war items would indeed make for a fine collection...Dano
I believe this is the Type 4 Pottery grenade, filled with Naval Type 88 explosive. Attached a drawing that you may find useful.

It has a Friction fuze, the small wooden cap had a matchbook like striker board around the edges used to ignite the fuze.

OK, that makes sense. Lex has it listed as a type 88 on his website.

@ Dano - it had a quick match fuze. Red phosporous and a wick of sorts. (see Sgtlynn diagram) :tinysmile_fatgrin_t
Early pattern should have a round body while the later type will have a flat bottom to prevent it from rolling around too easily. Have been told the very late production runs were not glazed. Anyone know if any of this equates to model numbers or something similar to the British Mark system?
Japenese grenade

I know the later ones were unglazed, but as far as a reference numbering system, not sure, beside being known as the type 4. Really cool grenades. Reading between the lines it looks it was a C.D. or reservist grenade that happened to make it to the front out of necessity. Dano
