PRICING

The prices I quote will be the YEN price. A good estimate of a landed costs is to divide the yen price by five to get your all in rands cost in South Africa. In other words if a fish costs 50,000 yen you can expect to pay around R10,000 for it in South Africa as a rough rule of thumb, this includes agent costs, handling, shipping, VAT and other costs. 

The size of the fish will affect the price slightly, with the bigger fish costing a slight bit more proportionately (as they cost more to fly over). But this will give you a near enough approximation of the costs.
