Hello! I'm Koji, a Japanese guitarist who lives in Berlin, Germany!

I've had 80 students (as of January 2020), from 7 to 67 years old! I teach a wide range of levels, from beginner's classes on tuning, simple string plucking, and guitar characteristics, to advanced classes on ad-libbing and learning how to learn the frequencies on the fingerboard, to lessons on how to make a professional sound by learning the quirks and phrases of artists in detail.

Anyway, I try to keep the atmosphere of my lessons free and fun!

For more information, please refer to the lesson contents for each level below.

Beginner's Course


First of all, learn how to enjoy guitar!

Be able to play something if someone asks you too!


Studying the characteristics of the guitar as an instrument.

Instead of just memorizing the chords (see note 1), learn how to play guitar a cool way?

It's important to stay motivated in the beginning!

Practice playing easy chords with abbreviated chords (see note 3).

C and F are difficult to play, so I'll omit them at first to make them easier to play.

Choose a song you like, play only the melody, and have fun playing the song together.

Practice grasping the distance of the frets on the fingerboard.

Intermediate Course


You will be able to play the song exactly like the original song, without any ellipsis.

You will be able to perform in public, on video, or with audio content in a band or as a soloist.

More than just “play something” you’ll get praised for it instantly!


Practice a few songs that have a nice chord progression.

I'll also explain why certain chords sound beautiful.

Learn various ways to play chords, arpeggios, fingerpicking, right hand patterns, etc.

What are chords in the first place? Why do we hear different sounds in the first place? (It's a bit academic) I'll explain why it's good to play that way, and explain how it works for each performance.

Practice the scale (see note 2).

Instead of simply memorizing it, how to play it, how to make it easier to play it, how to make it sound cooler? 

Using a simple scale, try ad-libbing with a blues progression (see note 4).

Advanced Course


Make the guitar your identity, expand your friendships with it, and prepare yourself to use it in the future, or actually work with it.

Make others want to play guitar when they see you!


Cover all the different types of scales (see note 2) and explain them, using not only positions but also the sounds that go into the scales.

Use chord tones (see note 5) to practice ad-libbing into jazz and pop music where chords are difficult to understand.

Train to be able to play at least 4 chord positions.

Understand what it means to use slides (see note 6), hammering (see note 7) and springs (see note 8) and understand the types of vibrato (see note 9) (sound intervals).

Mastering Bending 

The sound can be adjusted without being out of tune, the sound can be controlled by bending at half-tone intervals, and vibrato can be applied.

Note 1: A series of three or more notes that are pleasant to the ear when played simultaneously.

Note 2: A sequence of several related sounds, from low to high. It's mainly an indicator of the relevance of the sound you play solo.

Note 3: A chord that is made easy to press by removing a sound that does not damage the overall sense of sound even if it is removed under certain conditions.

Note 4: A simple song progression consisting of three chords, a popular chord progression because it allows you to play a single scale in a session.

Note 5: Each note contained in a chord.

Note 6: The sound is made by sliding the finger.

Note 7: To make a sound using only the remaining strength of the left hand, without using the right hand.

Note 8: Strumming a string with the force generated by hooking the fingers of the left hand.

Note 9: Swaying the string with the fingers of the left hand to sway the sound at regular intervals.

My motto in lessons is “Have fun and do the music you want to do!” but also “be able to play phrases and chords after practicing hard!”.

・Is he/she fundamentally an attractive person?

・Does he/she look sparkly, happy?

・It's not only whether or not the person is good at playing, but do they actually look cool when playing?

・Can you relate with the way they think?
