In November of 2023, DN Lighting was involved in a repair project for Osaka’s Mitsutera Temple (Daifukuin, Shippozan) cooperating in designing the lighting in the main hall. Let’s look at the company’s goals and prospects as it goes on the offensive to expand its market with this initiative.
Displaying technical and proposal capabilities through lighting design for a cultural property
In November 2023, indirect lighting manufacturing specialist DN Lighting was involved in a
repair project for Osaka’s Mitsutera Temple, cooperating in designing the lighting in the
main hall. Mitsutera is a Buddhist temple located in the city’s Minami business district. It
is beloved by the people of the area, warmly nicknamed “Mittera-san” and “The Kanon of
Minami.” A comprehensive renovation was launched in 2019 to utilize the land, and a 15-story
building was constructed to cover the main hall and completed in November 2023. The main
hall was reconstructed on the first through third floors of the building, and the fourth
floor and above were transformed into a building complex that houses a hotel and other
facilities.
DN Lighting used the renovation as an opportunity to design the optimum lighting for the
statues of the Buddha in the temple’s main hall. They discussed issues specific to temples,
such as main hall’s spatial presentation and the direction of the lighting design, and
whether nails and screws could be used in the historical building of the main hall (as metal
objects are traditionally avoided in temple construction). Fumiyoshi Kobayashi, section
manager of the Osaka Sales Office at the Western Japan Sales Department, Sales Headquarters,
spoke about the key points of the project.
“We asked Hiroyasu Yoshino—a lighting designer with an established reputation in the fields
of art galleries, museums, and cultural properties—to work with us as we repeatedly studied
improving color rendering and reproducing the original colors of the cultural properties.”
They focused on produced detailed effects, such as optimizing the overall lighting to bring
out the beauty of the cultural properties; optimizing the lighting effects, particularly on
the statues of the Buddha and the ceiling paintings, and installed indirect lighting that
emphasizes the white of the wall surfaces. What were the company’s goals for this project?
We asked Aya Takahashi, Manager of the Public Relations Department, Sales
Headquarters.
“This project is aimed at expanding our market by demonstrating our company’s potential
capabilities beyond cultural properties. Recently, as people are working remotely and
spending more time at home, and there is a trend toward rethinking lighting. A growing
number of people want to recreate hotel-like spaces in their homes. We aim to make a
full-fledged entry into the detached house market in the future, and believe that this
cooperation in lighting design for cultural properties will be an opportunity to appeal to
the market by showing the public our proposal abilities, technological strength, and
customization capabilities.”

The secret to differentiation through making use of line lighting fixtures
The company’s original main market is in the field of commercial facilities, such as
department stores and luxury brand shops. They offer a diverse lineup of products, in
particular display shelves and indirect lighting for spaces, providing compact indirect
lighting that “fits into and blends in” to the surroundings. It has received high praise for
its customization ability in proposing the ideal product for each customer’s needs. Based on
the know-how and knowledge they have accumulated with indirect lighting in these venues,
they are expanding their market to such as hotels, offices, hospitals, welfare institutions,
as well as getting involved with art galleries and museums.
Of great interest is that DN Lighting’s indirect lighting lineup basically consists of only
line lighting. In terms of structure, the lineup features many items, such as different
lengths and widths of lines, different color temperatures and light distributions, and
flexibility. However, they do not deal in general ceiling lights, instead focusing on line
lighting that responds to the various needs of their customers. How does the company
differentiate itself from competitors with only line lighting? Mr. Yoshimi Hirota of the
company’s Public Relations Department provides an explanation.




Major manufacturers have similar lighting fixtures, but they typically offer about 4-5 sizes
for a single product. In contrast, we offer about 40-70 variations for a single product. At
facilities, their shops and displays will be of various sizes, and in some cases the
products that major manufacturers provide simply will not fit. However, our company’s
products make it possible for the designer to create the space exactly as they wish. We
started as a manufacturer of fluorescent lamps, and although they have now been replaced by
LEDs, our long-accumulated expertise in light production is one of our major strengths.”
Also, the company has a manufacturing facility in Akita Prefecture, and approximately 80% of
all its products are produced by manufacturing subsidiary Akita DN Lighting. Manufacturing
products at its own domestic factory allows the company to provide consistent quality, fast
delivery, and customization to meet customer needs.

Desire to penetrate indirect lighting in the residential market
The company has established their presence in a niche market, overcame the economic
hardships posed by the COVID-19 pandemic, and is currently maintaining strong performance
due to high demand from the rush to construct overseas-affiliated hotels. What challenges
are they facing?
“Our products can be used in various ways, but they require a separate power source as well
as the space and budget to conduct a detailed inspection. Moreover, they require electrical
work, so we have not penetrated the residential market very much. However, with people
reevaluating the need for a better lighting environment, we are trying to get across the
benefits of indirect lighting not only for housing, lighting manufacturers, and architects,
but also to the general public by creating sales promotion material such as our Basic Book
on Residential Lighting,” says Mr. Kobayashi.

Going forward, the lighting industry expects to see a market expansion through controls
which make use of IT tools. DN Lighting plans to respond to this trend while remaining
committed to customization based on its technological capabilities and domestic factory
production. In fact, they are the only manufacturer of “Seamlessline” fluorescent line
lamps, and has no competitors. Their strategy is to capitalize on new trends by making a
range of proposals to major manufacturers based on these technological capabilities.
Mr. Hirota says, “We will not compete against major manufacturers. Going forward, we plan to
continue improving our products and services while further upgrading the items that our
customers demand”
