I'm not sure how to read their company, but it goes something like: Taichu Jitsugyou Kabushiki Gaisha (大中実業株式会社). Their store is located near Kyoto Station, about 15-minute walk. I'm not sure but I think they ship products to other parts of Japan (you can call them to make sure). They have different products-- from frozen vegetarian products (like soy ham) to textured vegetable proteins (TVP), to vegetarian seasonings et cetera.
You can check out some of their products shown in the pictures below. But that's not all they have. I didn't have time when I went there but I really wanted to take pictures of their products for my blog (because they haven't created their website yet). Just click on the picture to see the whole photo.
If you want to buy or ask about their products, you can contact them at 075-671-6022 or fax at 075-671-4531.
If you want to go to their store, the address is written on the picture on the right. I'm sorry I can't translate it for you-- I don't understand it very well. ^^;
