Quick video about the Sakura stamp catalog (原色日本切手図鑑) I purchased a few weeks ago
One thing I noticed they have different sections for stamps... even more so than Scott :(

Commemorative Stamps
Greeting Stamps
Furusato Stamps
National Park Stamps
New Year's Greeting Stamps
Definitive
.. Booklets
.. Air Mail Stamps

This looks to be the normal catalog, there is also a specialized version

The nice thing about the catalog is that it's in both English and Japanese
