I purchased this setup about 3-4 years ago at Isetan (around 80,000 yen). The brand is Infolio Plus (Isetan's original brand), but it was manufactured by Lonner Co., Ltd., which is also used in the drama "Hanzawa Naoki" and various other TV programs. The lapel uses a floating canvas construction, not the glued-in interlining often found in mass-produced items, allowing it to maintain its shape for a long time. This is a jacket-only listing. I think it can be used for Cool Biz or as formal everyday wear. The color is plain gray (with a slight sheen) as shown in the front photo, so I think it can be used widely. I usually only wear slacks, and I only wore the jacket occasionally for meetings. Therefore, I think it's in good condition for something I bought 3-4 years ago.
