Play Final Fantasy IV (US FF2) and Phantasy Star 2. Both have a good story and absurdly simple mechanics. You can overcome any challenge in either game by either leveling or looking up where the best equipment is.
If those games seem bullshit or too difficult the genre might not be for you. From a pure gameplay perspective, most of the constantly recommended SNES and PS1 JRPGs like FF6, FF7, and Chrono Trigger aren't actually that great of RPGs, and are mostly fondly remembered for being tech demos for the hardware they were on. Mid 90s Square was style over substance.
If you like those two, you can safely check out the rest of the Phantasy Star and Final Fantasy and Dragon Quest series. Phantasy Star I and IV, and Final Fantasy 6 are a lot easier than the two I recommended, but again, if you can't get through FFIV/PS2 you're probably better off playing some other story driven genre like ddventure games anyway. The proper JRPG experience is something like, "I can't wait to find out what happens next, and what combat/dungeoneering challenges I'll have to overcome to see it!"
SMT gets recommended a lot, but it's more of a CRPG series that just happens to be on console. Has much more in common with Wizardy, Ultima, and 80s D&D games than it does Dragon Quest or Final Fantasy.

Check out Phantasy Star 2 and The Final Fantasy Legend (AKA Saga 1) for Game Boy. The dialogue and story in both are great and thought provoking, but it's accomplished with very small amounts of text. There's absolutely no filler. All you do in both games is explore and fight. As I said earlier, JRPGs are a turn-off to a lot of people because people only recommend these bloated mid-90s games that are trying too hard to show off Mode7 effects, summoning animations, and FMV cutscenes. The best JRPGs have none of that bullshit.
