Abstract
In the Sakhalin Island, the oil show was discovered near Okha city in 1880. Hokushinkai (Japanese company) developed this oil and imported it into Japan in 1924. Japanese North Sakhalin Oil Co., Ltd. succeeded the business of Hokushinkai and continued until 1943.
56 Japanese died during 1923-1943 years and were buried in Okha. After 1943, none of the Japanese visited the Japanese grave of Okha.
In 1975, Sakhalin Oil Development Cooperation Co., Ltd (old SODECO) made the agreement (G/A) with the USSR to explore the shelf of the Sakhalin Island.
In the north-east shelf area, the Odoptu and Chayvo oil/gas fields were discovered. These oil/gas fields and the Arkutun/Dagi oil/gas field developed as Sakhalin-1 project. And the Luni structure and the Piltun/Astokh structure developed as Sakhalin-2 project.
The author worked in Sakhalin in times of the Japan and Soviet co-operational exploration based on G/A. But the foreigners who worked in Sakhalin were not able to be accompanied by a family in the Sakhalin.
In 2009, he guided his wife and visited Sakhalin, and she enjoyed sight seeing of the place that he worked in old days. And he recognized the present circumstances of the Sakhalin and difference with that of the USSR era.
Another purpose of his visit to the Sakhalin was to burn incense for the 56 Japanese deceased in Okha. But the graveyard was removed, and he recited the sutra from the hill which overlooked the lost grave.
