Does every Japanese Dev have a long running RPG series?

Intelligents systems (Fire emblem, advance wars) is strategy RPG
Nippon Icchi (Disgaea, Phantom brave, Stella Deus ) strategy RPG
Atlus ( Shin megami Tensei) RPG (Growlanser (publisher)) Strategy RPG publisher of a lot of lesser known Japanese developers
BAnpresto (Summon night) RPG (Super Robot wars) Strategy RPG

Only two of these are mainstream RPG series and IMHO arguably Suikoden is much better although I like both Shin Megami and Summon night series.

In strategy RPG no one beats Intelligent systems (although my favorite game in this genre is tactics ogre (now defunct Quest)).

Edit: I agree all of them seem to have thier own series.

Actually, the Growlanser series is made by Working Designs.
