If you are in Japan, you can buy these stuff at the vegetarian goods store in Kyoto.
If you are in the Philippines, you can check it out at Quan Yin Chay, Happy Veggie, and Tung Fang.
If you're somewhere else in the world, I saw some promising products at amazon like Butler Soy Curls, Betta Foods Imitation Chicken Chunks, and Bob's Red Mill TVP.
I'm sorry I haven't taken a photo of fresh soy protein in my local market. I don't usually buy it because my husband doesn't like it's taste. But the next time I'm not in a hurry doing the grocery, I'll make sure you get to see a photo of this. ^_~
Dried TVP Chunks
Commonly called TVP, meaning textured vegetable protein, this is a hard, tree-bark-like nuggets that needs to be soaked in warm water for ~20minutes or boiled for a few minutes to soften. You can flavor it however you want and it will give you a meaty texture to your dish. Just don't expect too much from it. It's not meat, so it don't be too hard on our TVP friends. They give a nice touch to some dishes, but I don't suggest putting it in all dishes as meat substitute. I personally don't appreciate it floating soggy in my soup. But it is really awesome barbecued.
Ground Soy Protein
Good in veggy meaty lasagna or spaghetti and so many other dishes, this may come as a textured vegetable protein, or a simpler soy protein. As soy proteins, it usually is the dried form of i think the soy bean byproducts when making soy milk or tofu. I don't know much about this, so if you do know, just comment them below. ^_~ thank you!
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. ^^;
