if you are a heavyweight and just want to spar without lots of technical
teaching, tenri is good. its a great place to go if you have another dojo to
train technique and want to go there for some good sparring.
if you can make the travel, mojica's, which is in west covina is great. they
train very hard with conditioning and drills.
sawtelle is also good.....so is venice in that area.
The dojo in West Covina is really nice. Like Sawtelle, it's in a Japanese cultural center. Both of them are cool for beginners on up. Tenri, from what I understand, is better for advanced judoka than beginners.
I wish I remembered the address for the West Covina dojo, but I'm sure you can look it up.
