This is a Spring Special Drama aired back in April this year in which Shunji Igarashi has a supporting role (doesn't he always?) It runs just over an hour long. Even with no subtitles, I personally found the show to be quite amusing. Sadly, I don't really think any official information exists in English, so I'm linking to a few relevant Japanese pages (probably contain some overlapped information).

Well, hope you enjoy if you take it.
