Field notes
The collection combines calculators, comparison tables, and practical guides rather than focusing on one narrow task. Its calculations reflect Japanese administrative and everyday contexts, including labor-law premiums, public holidays, furusato tax, Japanese units, and golf competitions. The homepage also separates work-focused material from household tools and says that inputs remain on the device. Planned additions include an ebook, an online course, and a serialized email letter.
