About

Hajun Ko (高河俊), who also works and posts under the name juniism, is a tattoo artist working across NJ and NY.

His signature work is irezumi, traditional Japanese tattooing. Most of the practice is large format: full backs, sleeves, chest panels, and leg pieces, with palm-sized single motifs taken on from time to time. Traditional designs, executed with modern technique.

A substantial part of the work is black and grey and colour realism, and a large share of clients come specifically for those. Portraits, religious subjects, and freehand smoke and background work sit alongside the Japanese pieces rather than beneath them.

He took first place in the Model Contest and second in Fake Skin Art at the 4th Korea Tattoo Convention TattooStar Awards in 2023, along with a commendation from the K-Tattooist Association. In 2024 he won both the Tattoo Artwork and Bottle Art categories at Inspire Fly High 2024, and exhibited at Nevermind Art Lounge in Seoul and in the tattoo! group show at Bincan Apgujeong.

Alongside the tattoo practice he is preparing a design reference volume on the Water Margin: the 108 heroes, the motifs attached to each figure, and how those figures are composed on the body in irezumi. In January 2024 he held his first seminar in Seoul on tattoo design and photographing finished work, attended by artists ranging from beginners to previous convention winners. He continues to enter convention competitions in Korea and on the east coast.

Booking

Tell me what you want and where it goes. Large Japanese work is booked as a series of sessions, not a single appointment.

Colour work reads differently on different skin, so this helps me plan the palette before we talk.

A few more details optional

Work is charged by the hour, and sessions are paid as they happen.
You only pay for the time we actually work that day, so there is no need to cover a whole project up front.
Rates move with the style, the detail, and whether the piece is colour or black and grey, so it is easier to talk it through than to post a number.
Tell me your budget and I will tell you what is possible within it.

A deposit equal to one hour of work holds your appointment, and it comes off that day's total.
For pieces running past three or four sessions, the final session is paid at the first, so both of us are committed to seeing the piece through.
Large work starts with a consult before anything is drawn.

For anything other than a booking, reach me by DM at @juniism_ or by email at loading.

Request sent. You'll hear back within a few days.
