Misuji-date

This pattern is called "three vertical lines" or misuji-date (三筋立). It's made up of three lines repeating at a constant distance.

Kintsū-jima

The next six patterns only differ in the number of lines that compose them. This first one, called kintsū-jima (金通縞), is made up of two lines or thin stripes, repeating at a set space.

Katsuo-jima

This pattern receives its name, katsuo-jima (鰹縞), from a fish called katsuo (skipjack tuna). The side of this fish's body changes its color from darker stripes to lighter ones.

Ryōtaki-jima

The name ryōtaki-jima (両滝縞) means "two cascades". I guess it's self-explaining :)

Taki-jima

Taki-jima (滝縞) means "cascade-stripes". It's the name given to this pattern since it looks like water falling to a lower level. This effect is attained by reducing the thickness of the lines as they move apart.

Ryōkomochi-jima

Now, the next pattern would be created adding an additional thin line to the other side of the bō-jima, ending with a pattern known as ryōkomochi-jima (両子持縞), meaning "having two children" for obvious reasons.

Komochi-jima

The next pattern is called komochi-jima (子持縞). Its name means "having a child", which refers to the thinner line accompanying the bō-jima.
