Taisei Coins - http://www.taiseicoins.com/ Specialty: Modern Japanese and modern world coins. Also some collectible NIFC bullion. Shop: Online shop and coin shows. Other information: They have a very nice web page, offer a blog and have a discount if you join their paid membership program. However, all information online is in Japanese and their prices are high because they import most of their merchandise from other countries, mints and sources to sell in Japan. Language: Japanese only, from my experience.
