Gunma dialect

The Gunma dialect (Gunma-ben or jōshū-ben) is a Japanese dialect spoken in Gunma Prefecture. It is part of the West Kanto group, along with the Chiba, Saitama, Tama, and Kanagawa dialects. It is different from the East Kanto dialects spoken in nearby Ibaraki and Tochigi (except around Ashikaga).

Regional variation
Gunma has three main sub-regions: the mountainous north and west, the central plain, and the southwest. The southeastern Ōra District shows features that mix West and East Kanto styles. In general, Gunma keeps the strong “g” sound at the start of words, like Saitama, rather than weakening it.

Key grammar and words
- The negation nai (ない) attached to the verb kuru (くる, “to come”) usually becomes kinai or kinē in most Gunma areas. In Agatsuma District it becomes konai or konē.
- The particle be (べ) is used to express volition, invitations, and conjecture. In standard Japanese these senses are usually linked to darō (だろう) for conjecture. Historically be covered all three, but by the Showa Era a form danbe appeared for conjecture.
- When be marks volition, it attaches to the conclusive form of Godan verbs and to the imperfective form of Ichidan verbs.
- In Agatsuma, the negation of kuru can be konai, which may be pronounced kobe (こべぇ) instead of kibe (きべぇ).
- There are several common be + ending patterns, such as -tate-danbe, -ki-be, -kun-danbe, -shi-be, -sun-danbe. In Tone and Agatsuma, be can become pe (ぺ) after a small つ (っ), and this pe form is also found in Tochigi and Ibaraki.
- Adjectives can use be with a nasal ending -kari, turning into -kan in many cases.

Language change over time
From 1980 to 2010, the difference between be and danbe diminished. By 2010, be was mainly used for volition, invitations, and conjecture again, and a new form nbe (んべ) started spreading across the prefecture. Some older forms (like imperfective + be) declined, while the simple conclusive form + be became more common.

Accent and pronunciation
- Most of Gunma’s speech is close to the Tokyo standard in pitch, with some areas like Itakura having less distinct pitch differences.
- In urban areas, three-mora nouns such as asahi (morning sun), inochi (life), and kokoro (heart/mind) tend to stress the first syllable, matching Tokyo. In rural areas, speakers often stress the middle syllable.
- A 1984 Takasaki study found middle-mora stress for words like asahi, kokoro, namida (tears), and hashira (pillar).
