Many of the models are animated, like this festival parade.

This gives you a sense of the scale of the area.

Elaborate models of various places in Japan are the star here.

The entrance to the area.

The centerpiece (literally) of Legoland Japan is Miniland.

Even the roof is themed like the green Lego "base boards".

The seats you sit on are oversized Lego creations.

Brick Party is a rather fun looking carousel.

From afar.

There's a few interactive gizmos around the perimeter and a screen with augmented reality.

This ride seems to follow a theme of what happens when you mash random Lego bricks together.

The layout is oval shaped with a single helix. In the middle of the helix is a tower with baby dragons taking flying lesson instructions from their parent.

Even the train is a bit more kid friendly, with Duplo block styling.

The station building.

Dragon's Apprentice in the shadow of its bigger cousin.

Cool height measuring stick.

Dragon's Apprentice is a much smaller coaster, built by Zamplerla.

Helices.

Perhaps the only criticism is that it's quite a bit back from all the pathways so bystanders can't really enjoy the riders-match.
