Ground beetles of suborder Adephaga are often considered bioindicators of natural environments because their habitats and abundances strongly depend upon environmental factors. Although their importance and usefulness are already known, there are limited data regarding voucher specimens in Japan. Biodiversity data based on voucher specimens are of high quality and reliability. In this data paper, we compile the records of Caraboidea collected mainly by Dr. Kazuo Tanaka. We also detail the time and locality of collection based on the labels of specimens deposited in the Institute for Agro‐Environmental Sciences, National Agriculture and Food Research Organization, Japan. This collection facility contains 15,675 records of 673 species collected from 1947 to 1997. All data are deposited in the Global Biodiversity Information Facility (GBIF) through the Japan Node of GBIF and are thus accessible through the GBIF portal under the Creative Commons Attribution 4.0 International license.

田甲一雄博士主要收集的甲虫（鞘翅目）的标本记录和地理位置

次级甲虫的地下甲虫通常被认为是自然环境的生物指示剂，因为它们的栖息地和丰富度强烈取决于环境因素。尽管它们的重要性和实用性已为人所知，但在日本，有关凭证样本的数据有限。基于凭证样本的生物多样性数据具有很高的质量和可靠性。在本数据文件中，我们汇编了主要由田中一雄博士收集的Caraboidea的记录。我们还将根据存放在日本国家农业与食品研究组织农业环境研究所的标本标签详细说明采集的时间和地点。该收集设施包含从1947年到1997年收集的673种物种的15,675条记录。
