JRC074 and NJM074 are surely the same part. Maybe they know their name in Japanese but they seem to have several names in english, including both NJM and JRC.
The "D" on the end just means DIP. You can get smaller M and V packages.

Yes, it is drop-in for the TI '074. It is not the same topology. JRC went through a phase of flogging every possible variant of the '741 chip. Their '074 is a 741 with inputs devices wired as JFETs. They simplified, and used newer processes; some of their chips are preferred over "originals". And some aren't. If not "better", maybe cheaper, if you negotiated hard.
