Among the well-known Japanese kanji dictionaries, the largest kanji entry set is found in the “Daikanwa Jiten” (大漢和辞典), which is a massive multi-volume kanji dictionary compiled by Morohashi Tetsuji. It includes about 50,000 kanji characters with detailed readings, meanings, sources, and compounds. This dictionary is considered the most comprehensive Japanese kanji dictionary available and is much larger than typical name dictionaries or general-purpose dictionaries.

In contrast, standard Japanese name dictionaries or general kanji dictionaries cover far fewer entries, typically ranging from a few thousand to tens of thousands of kanji, often focused on the 2,136 Jōyō kanji or the approximately 3,000 kanji in common use. The Daikanwa Jiten stands out by providing a historical and exhaustive collection that includes rare and archaic kanji.

Thus, for sheer volume of kanji entries, Daikanwa Jiten is the largest kanji dictionary. However, it may not be specialized on names alone but covers kanji broadly across the language.joyokanji+3

Among the Japanese name dictionaries previously listed, the one with the most distinct kanji entries is the Japanese Names Dictionary by the CJK Dictionary Institute (CJKI). It contains around 500,000 core Japanese names with extensive variants and kanji coverage, making it the largest repository of Japanese names and kanji variants available.

Other well-known general Japanese kanji dictionaries like Daikanwa Jiten have more overall kanji entries, but they are not exclusive to names. For Japanese names specifically, the CJKI dictionary has the most distinct kanji entries focused on personal and family names.wikipedia+1

Therefore, from the listed name dictionaries, the CJKI Japanese Names Dictionary contains the most distinct kanji entries.

Among the dictionaries listed, the one with the largest total kanji entry count is the “Dai Kanwa Jiten” (大漢和辞典), also known as Morohashi’s Great Chinese-Japanese Dictionary. It contains about 50,000 kanji characters and approximately 530,000 compounds, making it one of the most comprehensive kanji dictionaries ever compiled.

By comparison, other large kanji dictionaries like the Kodansha Daijiten have about 14,900 kanji entries, and the Kan-Wa Daijiten has about 20,000 kanji. The Dai Kanwa Jiten far surpasses these in size and depth[citation: 26].immersionlanguageclub+1

Therefore, from the known and listed large kanji dictionaries, “Dai Kanwa Jiten” holds the largest total kanji entry count.

The dictionary listing the highest total kanji count in the search results is the Dai Kanwa Jiten (大漢和辞典), which contains about 50,000 kanji characters. It is considered the most comprehensive kanji dictionary in Japan, spanning 12 volumes plus supplements and indexing over 50,000 kanji, far more than typical dictionaries focused on daily use kanji or names.edrdg+2

The dictionary in the search results that claims over 45,000 kanji is the 13-volume Morohashi Daikanwajiten (Morohashi, 1989). This dictionary has more than 45,000 kanji entries and is known as one of the largest and most comprehensive Japanese kanji dictionaries.acm+1

The result that explicitly names the Morohashi Daikanwajiten as having over 45,000 kanji is found in the paper titled “Multiple indexing in an electronic Kanji dictionary” and references the 13-volume Morohashi Daikanwajiten (Morohashi, 1989) having over 45,000 kanji entries.academia+2

Additionally, the Wikipedia page for Dai Kan-Wa Jiten states that it contains about 49,964 head entries for characters, with over 50,000 character entries mentioned in some references.wikipedia+1

These sources confirm the claim of the Morohashi Daikanwajiten containing over 45,000 kanji.
