You can use UV light (black light) to show up repaired cracks as the filler will most likely glow a greenish colour under UV light. Open surface vessels or grain lines that appear to look like cracks won't do that.

A new hairline crack won't show up under UV, but it will be more distinctive and defined compared to a surface vessel.

It has been said by some that cracks are always straight lines, only wood grain is rarely ever straight and cracks follow the line of grain no matter how much that meanders. Cracks don't run across the grain.

If you do see what looks like a newly formed crack, mark it with a pencil along its length and also how far along the joint it runs (if it doesn't terminate in a tonehole, pillar hole or slot) to make it easy to find next time as it can close up. Yamaha suggest to mark the crack line with chalk.
