Notaries, Reference Directories, inoshi.cc and MIPRO's Official Guides
Notary directory, reference wikis, inoshi.cc's incorporation/tax guides, and MIPRO's official English guides to setting up a business.
The official directory of Japanese notaries is useful for finding one when a company's articles of incorporation need notarization; the same site hosts a guide to My Number Card electronic signatures. An article covers registering a business at a private home as its legal address, relevant for anyone who wants to use a home address instead of renting a separate office, and another covers business-visa requirements including the 5-million-yen capital condition. Two alternative reference/service projects were mentioned as counterparts to inoshi.cc: Serendia and an open wiki-encyclopedia about life and business in Japan, whose editors can be reached via Telegram for edit access. inoshi.cc itself is a reference project for companies that have already incorporated in Japan, offering a tax calendar and a series of practical guides: post-incorporation steps, director salary, a glossary of terms, consumption-tax refunds, the kakutei-shinkoku annual tax return, a currency-rate aggregator, tax residency, resident-tax notification dates, and a guide to the SMBC Trunk banking product. MIPRO publishes official English-language PDF guides on establishing a company in Japan and on corporate taxes, a good English-language starting point for understanding the structure of setting up a business; a LinkedIn guide to incorporation and another on corporate banking (the banking one dates to 2022 and is partly outdated, though its bank list remains useful) supplement these with a practitioner's perspective. Two further resources cover the 労働条件通知書 (working-conditions notice) an employer must issue at hiring, the concept of chonaikai neighborhood associations relevant to choosing a business or home location, and a book on entrepreneurial mental health.
