Japanese curry roux question

These are so good. But they are never as spicy as I expect them to be
I recently saw “Extra Hot” at the local Asian market, so I picked it up. Still not that hot. Next time I may throw a couple of dried arbol chilis in.
Japan doesn’t like spicy food for the most part. In the last 10 or so years they’ve gotten a little better about it, but it used to be that just about any restaurant with a “extremely hot” option (for ramen or whatever) would have a barely detectable level of heat. Just about the hottest thing you could commonly find was tabasco.
