Finally! I think I've found the best place to buy gold and silver in Tokyo. The place is called Ishifuku Metals and it is located in several locations around Japan. In Tokyo, it is just a 20 second walk from Kanda station on the JR line.
I went there the other day and found that Ishifuku's price on a 20 gram gold bar was a full ¥2,000 yen lower than the price on the place I usually go to in Okachimachi (I won't go there anymore!).
Ishifuku Metals is not a just wholesale metals dealer, they are a metals factory that provides materials for medical uses and dentistry as well as for product manufacturers. Since they are a factory, buying from Ishifuku gives you rock bottom prices since there is no middle man. And, of course, they also sell to the public just like a regular gold or precious metals dealer.
Ishifuku Metals has been in business since 1930 so you know they are a reputable company and the service is excellent..
Address in Tokyo is:
Uchi Kanda 3-20-7, Chiyoda-Ku, Tokyo, 101-8654
