Rare! BulBul Tarang Indian Instrument Like New

Bulbul Tarang, an Indian musical instrument.
This traditional instrument, with roots in Japan's Taisho Koto, has been uniquely customized in India with sympathetic strings and pickups that resonate through an amplifier.
I purchased it new from India last August for approximately ¥110,000, including shipping and taxes.
Although new, due to Asian quality standards, the finish was poor, and there were numerous scratches upon arrival.
The screws interfered with the hard case, so they were replaced.
The hard case did not fit the instrument properly and rattled, so it has been modified with cushioning material for protection.
While specialized strings are available on Amazon, the 1st and 2nd strings of an electric guitar can be used as a substitute, which is likely more cost-effective.
This listing is for the instrument and its hard case.
Sound has been tested by connecting it to an amplifier. The case has a new wood scent when opened.
Due to high shipping costs, significant price reductions cannot be accommodated.
This is a rare instrument not often seen in Japan, so please consider this opportunity.
