If you loved Modest Heroes, try Mary and The Witch's Flower
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Hiromasa Yonebayashi, and they both carry the tender mood tag, and they sit in Adventure / Animation / Fantasy territory. If that's the register that drew you to Modest Heroes, the second film will land in a comparable space — through a different lens.

What Mary and The Witch's Flower is
Apparently witchy things happen in the countryside. Mary finds a mysterious flower and broom. It all gets rather enchantingly chaotic.
