WiD Lite
Sakawa Co., Ltd. (Headquarters: Toon City, Ehime Prefecture, President and Representative Director: Toshitada Sakawa) will release "WiD Lite", a new model in the ultra-wide short-throw projector "WiD" series, starting April 22, 2026. This is a conventional low-cost model that maintains the overwhelming large-screen projection quality while specializing in display functions to achieve an accessible price range.
This series was evaluated for its contribution to the educational field and won the Excellence Award at the 10th "Monodzukuri Nippon Grand Award" in March 2026.
The WiD Series celebrating its 10th anniversary since launch
Although multifunctional electronic blackboards have been introduced in educational fields, there have been cases where they are not fully utilized due to reasons like "unable to master them" or "insufficient visibility." In addition, recently, overtime work and overwork of teachers have become serious social problems, creating the issue that they cannot pour enough energy into "classes" where they face the children.
As a blackboard manufacturer, we solved this problem with the blackboard projector "WiD", which multiplies digital power while retaining the merits of the analog blackboard that has been used for many years. Thanks to everyone's support, WiD will celebrate its 10th anniversary this year. Currently, it has been introduced to schools and local governments nationwide, being utilized in over 10,000 classrooms.
Main features of the WiD series
Adopting School: Joshibi High School of Art and Design / Junior High School
Because you can project digital teaching materials largely onto the blackboard and directly write with chalk in the empty spaces, classes that fuse the advantages of digital and analog are possible without breaking the traditional blackboard-writing style.
■ Over 4500 lumens ultra-wide projection
Projects a large screen with an "aspect ratio of 16:6" at a ratio perfectly matching the size of a typical blackboard or whiteboard (width 3.6m, height 1.2m). Projection in 4:3 or 16:9 is also possible.
■ Move the screen with the digital slide function
The projected screen can be slid to the left, center, or right using a remote control, allowing you to write from the right for Japanese classes, and from the left for English and Math. Patented: Patent No. 6608080
■ Display two systems side-by-side simultaneously
It is the size of two traditional 4:3 screens side by side. Because it can output separate video systems to the left and right (2-screen function), it can be used like "displaying the teacher's terminal and student's terminal screens side by side."
The new model "WiD Lite" specializing in display functions appears on April 22
Following the GIGA School Concept, the need to present more materials in the classroom has increased, and the size of the display screen of projectors and displays is considered important.
"WiD Lite" (Model number: SP-UW4500-LT) features a simple specification that removes the electronic pen (interactive function) while keeping the biggest strength of WiD, "ultra-wide projection of up to 130 inches that fills the blackboard" and the brightness quality.
1. An easy-to-introduce price range model
By narrowing down the functions to "projecting and showing", a low-cost version of the conventional model was realized.
2. Simple specifications without an electronic pen
Recommended for those who do not need an electronic pen (no interactive function).
3. "Projecting and showing" is equivalent to the conventional model
The ultra-wide large screen projection quality remains exactly the same.
[Regarding the sale of conventional models]
As of April 2026, the conventional WiD model "WiD 4500" (Model number: SP-UW4500) will continue to be sold.

Won the Excellence Award at the 10th Monodzukuri Nippon Grand Award
The WiD series was evaluated for its contribution to reducing teachers' burdens and improving students' concentration through the digitization of blackboards up to now, and won the Excellence Award at the 10th "Monodzukuri Nippon Grand Award (Traditional Technology Application Category)".
Award Title:
A blackboard shop founded in 1919 reduces teachers' burdens by digitizing blackboards! Japan's first dedicated blackboard projector "WiD"
Award Summary:
As a blackboard shop that has been making blackboards for over 100 years, we developed a dedicated blackboard projector that grasps the needs of the field. We realized classes that fused digital and analog. Through its introduction, blackboard writing time has been significantly shortened, the burden on teachers suffering from overwork has been alleviated, and it has led to improved student concentration through well-paced classes. Students' tablet terminal screens can also be projected, making it highly compatible with active learning. We also developed a projection-compatible blackboard with a special surface treatment to make it easier to project images. Ensuring chalk can be used as conventionally, etc.
