Hachise overcame these regulatory issues by adapting special structural calculations that would enable Kyo-Machiya built by traditional construction methods to meet earthquake-proofing criteria. In the past, few people had even attempted to build new traditional Kyo-Machiya because the structural calculations involved with traditional construction methods under the current law would be too complicated in many ways. Such calculations, as well as their approval process, would require substantial time and effort. Even if approved, the construction itself would require time-consuming manual work done by skilled craftsmen as well as a larger volume of timber. Hachise, however, has unflaggingly strived to realize these calculations. Having worked hand-in-hand with a specialist organization for several months, the company ultimately obtained approval for constructing entirely new Kyo-Machiya.
