These characters are predominantly "cute" female characters. The decorations usually involve paint schemes and stickers. Automobiles are called itasha, while similar motorcycles and bicycles are called itansha (Ita-Motorcycle) and itachari (Ita-Bicycle), respectively. The cars are seen prominently in places such as Akihabara (Tokyo), Nipponbashi (Osaka), or Ōsu (Nagoya).

- PHYTHM Guitar Parts -

PHYTHM’s name was taken from combination of “physical”, “ism” and “rhythm”.

Mr Tanikawa came up with this name because he wanted to make something that can bring out the maximum physical possibility of the guitar.

There are a lot of guitars made with excellent quality wood and excellent processing technology, but were assembled in mass produced products… Crucial parts like Saddles and Tremolo Block, where guitar strings vibrate thru to its body… 

PHYTHM Guitar Parts was born to change that trend. 

More carefully detailed saddles and tremolo block to maximize your guitar strings’ vibration…
