Production Tenryu/Wada Factory, Japan
From 1946 to 1968 a 5-digit sequential system is used. However, there
is no indication of the year of production in this system.
A nice and simple 6-digit system is used in the period from 1969 to1984.
The first two numbers represent the year.
The next two digits represent the month and the last two digits represent the number of the unit (serial number).
For example: 800629
The 29th guitar that was built in June 1980.
In the short period of 1985-1986 a 6-digit serial number has been used but the month is not displayed.
The first 2 numbers are the year.
The last 4 digits are the number of the unit (serial number).
For example: 860123
This stands for the 123th guitar built in 1986.
Production Custom Shop, Japan
In the 1966-1985 period, successive serial numbers from 001 to 1042 were used.
To find the production year, you have to make a rough estimate
The closer to 001 it is closer to 1966 and the closer to 1042, the closer
to 1985.
From 1986-1990 the serial numbers have 1 letter followed by 4 digits.
The letter represents the month and follows the same system for months as the most common system.
(see year and month coding system)
The first number stands for the year.
The last 3 digits represent the number of the unit (serial number).
For example: K8123
This would be a guitar built in April 1988 and the 12th guitar of that day made in the custom shop.
The K is April according to the coding system and the year must be
1987, since this system was only used between 1986 and 1990.
In the period of 1991-1996 one used a 2 letter, 3 digit, then 1 letter system.
The first letter is the year and follows the same coding system.
The second letter is the month and also follows the same coding
system. The 3 numbers represent the unit number, but in this case the unit numbers started with 701 for unclear reasons. So the first unit of the day was not 001, but 701.
The last letter is an unknown internal factory code.
Example KN712J belongs to the 12th guitar produced in July 1994.
K N 712 J is the 12 th guitar built in July , 1994 .
In the period of 1997-2003 the same method was applied as for 1991
to 1996 with 2 differences.
There is no more internal factory code at the end, and the unit numbers start at 001 instead of at 701.
For example: HL032
The sample serial number here represents the 32nd guitar built in May 2001.
From 2004 to 2021 a 3 letter, 3 number, 1 letter system is used.
The first 2 letters represent the year in this case. So you get the decade here.
The third letter represents the month according to the coding system.
The 3 digits represent the number of the unit. (serial number)
The last letter is an internal factory code.
For example: QNK026C
This guitar in the sample serial number was the 26th guitar built in April 2007.
The Q stands for a 0 and the N is a 7, which means 07 for 2007.
QN K 026 C is the 26 th guitar built in April , 20 07 .
For the period of 1997-1999 the same system is used as that for «Custom Shop 1991-1996» except that the unit number starts at
501 with the exception of 701.
From 1999-2000.
The first letter is the year. The second letter the month.
The 3 digits are the number of the unit.(serial number)
The unit number starts at 200.
For example: PX267
This was the 67th guitar made in October 1999.
From 2001 to 2021 they uses a system with 3 letters, 3 digits, 1 letter.
The first 2 letters represent the year. The third letter represents
the month and the 3 digits are the number of the unit (serial number).
The last letter is an internal factory code
For example: QJH055B
This would be the 55th guitar that was built in January 2003.
Production Kaohsiung, Taiwan
An eight-number system is applied here from 1971-2001 The first digit represents the year. The second and third digits represent
the month. The fourth and fifth numbers represent the day of the month.
The last three digits are the number of the unit (serial number).
Because there is only one digit for the year, there are duplicates with this system because it repeats itself every decade.
For example: 60708077
This example serial number was the 77th guitar built on July 8 in 1976, 1986 or 1996.
At the end of 2001, Kaohsiung changed the 8-digit system into a 3-letter 6-number system.
The first 2 letters represent the year. The third letter represents
the month. The first 2 digits are the day of the month and the last
4 digits are the number of the unit.(serial number)
