Tsuji Hongo Tax Corporation (Headquarters: Shinjuku-ku, Tokyo; Chairperson: Saeko Kuwaki), in collaboration with Tsuji Hongo IT Consulting Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President and Representative Director: Ken Kuronita) and OSK Co., Ltd. (Headquarters: Sumida-ku, Tokyo; President and Representative Director: Hiroshi Hashikura), will co-host a free online seminar titled "How Many More Years Can Your Core System Last? Understanding the 'Three Lifespans' That Affect Management Decisions" on Tuesday, June 16, 2026.

Behind the comfort of a functioning core system, cases of on-site reliance on specific individuals and complex Excel operations are generating hidden costs and hindering swift management decisions. This seminar will organize the black-boxing of operations and delays in decision-making as a "silent collapse" and visualize them from the perspectives of system, personnel, and operational lifespans. Instead of a large-scale overhaul requiring massive investment, the seminar will explain realistic criteria for IT investment and the next steps at an optimal pace for each company, incorporating diagnostic workshops.
