Nice catalog, Japanese text with some English titles
If you are into collecting Japanese train models, this catalog is a nice reference guide. It is very comprehensive, about 300 pages, filled with hundreds of colorful pictures and descriptions of Tomix N scale scale (and some HO) train products. Although the text is in Japanese, Tomix at least gives you names of the trains in English, which helps; Kato, GreenMax, and Micro Ace catalogs do not do this. The pictures are worth a thousand words, and if you desire use Google Translate on the text, and if you look to Wikipedia you can usually find out information about the train you are looking at.
Remember, this catalog is published for the Japanese and is good catalog if you understand what you are buying.
