Well, it's fairly new, at least!
I launched Savory Japan, a website about Japanese cuisine, travel and culture in late March, just in time for Cherry Blossom season. It's a new kind of site, comprehensive, vast and deep: with no advertising, beautiful photos, and in-depth articles.
Included is a glossary of Japanese ingredients, articles on Japanese food philosophy, recommended restaurants and ryokans and of course, recipes.
Enjoy, and please feel free to comment or ask questions here on on the Savory Japan blog.
