4 large eggs (about 50 g each without shell)
1 sac mentaiko (spicy pollock/cod roe), about 40 g
2 tbsp Japanese (Kewpie) mayo, divided — 1 tbsp for the filling, 1 tbsp for the drizzle
2 thin slices deli ham
2 tbsp dashi (or 2 tbsp water + a pinch of dashi powder)
1 tsp sugar
½ tsp light (usukuchi) soy sauce
1 scallion, thinly sliced
neutral oil, for the pan

The Way

Slit the mentaiko sac lengthwise and scrape the roe out of its membrane with the back of a knife. Stir half of it together with 1 tbsp Kewpie mayo to make the mentaiko-mayo filling; keep the rest of the roe aside for the top.
Crack the eggs into a bowl and beat with the dashi, sugar, and light soy sauce until fully blended but not foamy — drag the chopsticks along the bottom to break up the whites so the layers stay smooth.
Wipe a tamagoyaki (or small nonstick) pan with oil and heat over medium-low. Keep it gentle the whole way — high heat browns the egg and toughens it; you want pale, tender yellow layers.
Pour in a thin layer of egg to just coat the pan. When the top is barely set, lay a slice of ham near the far edge, spoon a line of mentaiko-mayo across it, and roll the egg toward you into a log at the far side of the pan.
Oil the empty pan, pour in the next thin layer of egg, and lift the roll so the raw egg runs underneath. Let it set, add the second slice of ham and more mentaiko-mayo, and roll again — repeat until all the egg is used, building the spiral thicker each pass.
Tip the roll onto a board (a bamboo mat helps square it off) and rest 1 minute, then slice into thick pieces to show the spiral cross-section — golden egg wrapping ham, orange roe, and creamy filling.
Arrange cut-side up on a white plate, zigzag the remaining 1 tbsp Kewpie mayo over the top, dot with the reserved raw mentaiko, and shower with sliced scallions.

midnight tip — keep the heat low and don't overcook the roe. the reserved mentaiko goes on raw at the very end so it stays glossy and briny; cooked-through roe turns pale, grainy, and loses its punch.

Questions

Why did my roll fall apart when I tried to fold it?

Usually the egg layer was too set before you rolled, or the pan ran too hot. Roll each layer while the top is still slightly wet and tacky — that moist surface fuses to the next layer like glue. A fully dry, browned sheet won't grip and just cracks open.

Can I use tobiko or regular cod roe instead of mentaiko?

Yes. Plain (non-spicy) tarako cod roe works the same way with a milder, less peppery flavor. Tobiko or ikura will read more as crunchy pops than the creamy spread mentaiko gives, so mix them into the mayo rather than expecting the same smooth filling — and add a pinch of chili if you want the spicy edge back.

How do I keep the egg from browning?

Lower heat and a little patience. Cook over medium-low so each layer sets gently to pale yellow, and lift the pan off the burner for a few seconds between pours if it's getting too hot. Browning comes from the pan being too hot, not from cooking too long — a tender tamagoyaki is cooked slow, not fast.
