Amazing Facts About Japanese Yen

Amazing Facts About Japanese Yen

A fun way to get a perspective on another country’s history and culture is by looking at the currency used. The materials and design that go into making them can say a lot about what a country holds dear.
So, why don’t we take a quick look through the modern coins used in Japan and learn a little about why they look the way they do and some other tidbits along the way such as what happens when you microwave a one-yen coin and why you shouldn’t do it.
Let’s start with those beloved little bits of pocket ballast: 
The One-Yen Coin.
 Diameter: 20mm
Weight: 1g
100% Aluminum
For Japanese coins, “heads” and “tails” aren’t easily understood. Although it’s not a hard and fast rule, most people seem to say that the side with the large number and/or the year printed is tails. In the case of the one-yen coin, heads shows us a picture of a young tree. The artist who created it apparently told a priest which tree it was based on, but he later admitted it was a lie and he just imagined it.
Like many small currencies of its type, the one-yen coin costs more to make than it’s actually worth. The amount of aluminum used alone is worth 0.7 yen, so after including all the other overhead you’re looking at about 2 yen a coin to produce.
The pure aluminum used gives this coin some unique properties too. First, it might be the only coin that floats on water. Actually if you were to toss the coin or push it down with your finger it would easily sink. The density of the coin is not buoyant, but its light weight allows the surface tension of the water to hold it up.
In addition, if you were to put a one-yen coin in a microwave, it would get all squishy. We would try it, but it’s a violation of the Monetary Damage Control Act and punishable by up to a year in prison or 200,000 yen fine.
The Five-Yen Coin
 Diameter: 20mm
Weight: 1g
100% Aluminum
For Japanese coins, “heads” and “tails” aren’t easily understood. Although it’s not a hard and fast rule, most people seem to say that the side with the large number and/or the year printed is tails. In the case of the one-yen coin, heads shows us a picture of a young tree.

The Five-Yen Coin
Diameter: 22mm (hole = 4mm)
Weight: 3.75g
60-70% Copper; 40-30% Zinc
This coin has a distinctive yellow coloring that’s made from the high content of zinc it possesses. This material combined with the widespread use of the coin provided a stable and easy way for researchers to measure radiation dosages indoors and out of all areas during the 1999 nuclear accident in Tokaimura.
Aside from its bright hues, this coin has a whole bunch of optimistic symbolism packed into it. On the heads side we can see horizontal lines representing water, from which a rice plant is emerging. Also around the hole (which we’ll get to later) are gear teeth. These symbolize Japanese agriculture, fisheries and industry.
On the tails side there is also a pair of sprouts which is said to symbolize Japan’s growth into a democratic nation. Even the name in Japanese (go en) is synonymous with good connections and this coin is the first choice for making a wish at shrines or kept in a wallet for luck.
The 10-Yen Coin
Diameter: 23.5mm
Weight: 4.5g
95% Copper; 3 to 4% Zinc; 1 to 2% Tin
With its high amount of copper, the 10-yen coin is probably the ugliest of the bunch. However, it may also be the most profitable. If you were to have 100,000 of these coins in your possession it would be worth roughly (depending on the dealer) 1,005,400 yen versus their 1,000,000 yen face value.
Depending on the year of the coin, they can be valued from 10 to 20 yen a piece. The most valuable one is a Giza 10 (Jagged 10) from the year Showa 33 (1958). This was the last year such a coin was made with a jagged edge, and since it was the last year the fewest were issued, making the Giza 10 the rarest of them all and worth about 50 yen.
Prior to the late 1950s, the 10-yen coin was the most valuable, so a jagged edge was added to help distinguish it from other coins. Later on, when the 50- and 100-yen coins came out, the jagged edges were passed onto them. 
The 50-Yen Coin
Diameter: 21mm (hole = 4mm)
Weight: 4g
75% Copper; 25% Nickel
Like the five-yen coin, the 50-yen coin can be easily distinguished by the hole in the center. This wasn’t always the case though. Japan figured it could kill three birds with one hole. First, it helps to save on material costs. Secondly, it makes them more difficult to counterfeit. Finally, it helps people tell them apart more easily, even simply by touch. It’s said that the five-yen coin was primarily given a hole to save materials following the war when rapid inflation was occurring.
On the other hand, the 50-yen coin was given a hole because for the first couple years of its non-perforated existence, it was annoyingly similar to a 100-yen coin. As the two coins became even more similar over the years in terms of material and images (the 50-yen coin has a chrysanthemum whereas the 100-yen coin has a sakura), that little hole has become even more important.
The 100-Yen Coin
Diameter: 22.6mm
Weight: 4.8g
75% Copper; 25% Nickel
The 100-yen coins has changed a few times over the years. The heads image went from an Asian phoenix to a rice plant to a cherry blossom. The material also went from a silver, copper and zinc alloy to a mix of copper and nickel. However, through all of this the size and weight of the coin hasn’t changed in the slightest since it was first issued.
The 100-yen coin was also Japan’s first commemorative coin issued in 1964 to celebrate the Tokyo Olympics.
The 500-Yen Coin
Diameter: 26.5mm
Weight: 7g
72% Copper; 20% Nickel; 8% Zinc
The 500-yen coin is the newest coin in Japan and potentially the most valuable standard currency coin in the world depending on foreign exchange rates (the Swiss five-franc coin is one of its biggest rivals).
The 500-yen coin is also special in that it has tiny letters hidden throughout the tails side, spelling N-I-P-P-O-N in 0.2mm letters.
