Teranishi FUJIYAMA IRODORI Akane Red 12 ml Fountain Pen Ink
Teranishi FUJIYAMA IRODORI Akane Red 12 ml Fountain Pen Ink interprets the vermilion glow of Red Fuji, a Japanese symbol of good fortune. Made in Japan and supplied in a compact glass bottle, it adds a warm, elegant colour to journals, letters, calligraphy and drawing.
The vermilion glow of Red Fuji
Mount Fuji was inscribed as a UNESCO World Cultural Heritage property in 2013 for its importance as an object of worship and a source of artistic inspiration. Season, weather and time of day continually alter its appearance, producing landscapes that have shaped Japanese art and visual culture for centuries.
FUJIYAMA IRODORI translates those changes into six inks linked to individual views of the mountain and to Japan’s sensitivity to subtle colour. Akane Red is based on Red Fuji, the striking moment when sunlight turns the mountain a vivid warm colour. In Japan this appearance has long been treated as a favourable sign. Teranishi translates the scene into a brilliant, elegant vermilion that adds warmth and energy to the page while remaining connected to the refined palette of the series.
Designed for pens, journals and creative work
This water-based ink is formulated for fountain pens that accept bottled ink. Its vermilion-red character suits headings, accents, journals, letters, calligraphy, creative notes and small illustrations. It is a useful choice for writers seeking a warm Japanese colour that stands out without feeling like a generic bright red.
Its appearance may shift with paper, nib width, ink flow and surrounding light. These variables allow the same bottle to produce different nuances across individual pen-and-paper combinations. Before changing colours, rinse the fountain pen’s nib section with clean water until it runs clear.
Secure the cap after every use to limit evaporation. Store the bottle away from high temperatures, excessive humidity and direct sunlight, and keep it out of the reach of small children.

Frequently asked questions
Will it work in every fountain pen? It is intended for pens that draw bottled ink through a converter, piston or another compatible filling system. A cartridge-only pen will need the correct converter before it can fill from the bottle.
Is this ink permanent or waterproof? Teranishi identifies it as water based and does not market it as permanent or waterproof. Writing that must withstand moisture should be produced with an ink specifically formulated and tested for that requirement.
What inspired Akane Red? Teranishi associates Akane with Red Fuji, a vivid appearance regarded as a symbol of good fortune. The colour is presented as a clear, elegant vermilion inspired by the moment when the mountain seems to glow.
Why use a 12 ml bottle? The smaller volume makes it easier to explore a special colour, rotate several inks and finish a bottle. It also requires little storage space, which is useful for writers who keep multiple pens inked in different shades.
How should a pen be cleaned before changing colours? Empty the previous ink and rinse the nib section with clean water until it runs clear. Allow it to drain before filling again so residue from another colour or formulation does not alter the new ink.
The history and philosophy behind Teranishi
Teranishi is the surname of the company’s founder, Choichi Teranishi. After three years learning how to manufacture ink, he established the Osaka workshop that became Teranishi Chemical Industry in April 1916, when he was only 18. Its earliest output included writing ink and coloured pencils made in Japan.
The business emerged when imported products still influenced much of Japan’s writing and art-material market. Teranishi set out to produce domestic inks and drawing supplies capable of competing through quality. Colour, useful writing tools and personal expression have therefore been connected throughout the company’s history.
Guitar is not a separate company; it is Teranishi Chemical’s historic commercial mark. The manufacturer states that its precise origin has not been documented and preserves two possible explanations: the popularity of guitars in the Philippines, an important export destination at the time, and the association between the rich colours of art and musical notes.
The earliest Guitar emblem showed Benzaiten holding a traditional Japanese biwa. It later changed to a queen with a guitar before developing into the current symbol, which combines a crown, a musical note and the six letters of GUITAR. The identity connects Teranishi’s work with inks and art materials to the worlds of music and colour.
Teranishi’s continuity was hard won. Its facilities and materials were destroyed during the bombing of Osaka in 1945, yet production resumed in February 1946. Akane Red has a natural place in this history of renewal: a luminous colour associated with good fortune and a fresh beginning.
FUJIYAMA IRODORI carries that experience into contemporary fountain pen use by transforming Japanese landscapes and colours into tools for writing, drawing and communication. Akane Red gives the philosophy of the series a specific view of Mount Fuji while remaining practical for modern creative work.
“When Fuji turns red, every line carries the light of a new beginning.”
