Katsuobushi is skipjack tuna that's been simmered, smoked over hardwood, sun-dried, and often fermented with mold until it's hard as a block of wood, then shaved into flakes. It's the backbone of dashi and the smoky drift of flakes on top of okonomiyaki. The good stuff comes from makers who take the smoking and shaving seriously, not a dusty bag of powder.

Naoko Takei Moore's Japanese-cooking shop (known for its donabe clay pots) carries premium katsuobushi shaved from blocks made by Matoba Suisan in Makurazaki, Kagoshima, the town that's the heart of bonito production. She sells it in an extra-fine shave that melts into dashi and drifts on top of hot dishes. Everything is chosen hands-on and shipped nationwide.
Why it isn't on AmazonNamed-producer katsuobushi from a specific Makurazaki maker, in a proper fine shave, is a curator's pick; a generic bag tells you nothing about how or where it was smoked.
See it at TOIRO →This importer travels through Japan to build relationships with small artisan producers, then brings their katsuobushi, soy, vinegar, and miso to US kitchens with the makers' stories attached. It's the deep-catalog option for building a real dashi pantry from one source, with free shipping over $75.
Why it isn't on AmazonArtisan katsuobushi sourced straight from named small producers is a relationship business, not a commodity import routed through three middlemen.
See it at The Japanese Pantry →The Portland, Maine seafood house that supplies top restaurants also sells cured bonito (katsuobushi), skipjack put through repeated rounds of drying and smoking into the hard, resinous block that shaves into flakes. Orders move on UPS Next Day Air, so it arrives fast. A fishmonger's take on the ingredient rather than a grocery import.
Why it isn't on AmazonA serious seafood house treating katsuobushi as a cured-fish product is a different sourcing lane than a shelf-stable grocery bag, and the fast shipping shows they handle it like fresh product.

Add your brand →They're the same thing: katsuobushi is the Japanese name for dried, smoked, often fermented skipjack, and 'bonito flakes' is the English label for the shavings. Quality varies enormously, though. Thicker shavings make a stronger, richer dashi; the delicate hair-thin katsuobushi is what you pile on okonomiyaki and takoyaki so it dances in the heat.
For a basic ichiban dashi, heat water with a piece of kombu, remove the kombu just before boiling, then add a generous handful of katsuobushi and turn off the heat. Let it steep a few minutes until the flakes sink, then strain. Don't boil the flakes hard or the stock turns bitter and fishy; gentle heat pulls clean smoky-savory flavor.
Depends on the job. Thin, fine shavings dissolve fast and are best for quick dashi and for topping dishes where you want them to flutter. Thicker shavings (atsukezuri) take longer to steep but give a deeper, more robust stock, good for hearty soups and simmered dishes. Many cooks keep both.
Keep shaved katsuobushi in an airtight bag or container away from heat and humidity, since it's dry and absorbs moisture and odors quickly. It keeps for months sealed but slowly loses aroma, so buy sizes you'll use. Whole blocks last far longer than pre-shaved flakes, which is why serious cooks shave to order.
